Misceo is a Latin verb that means “to mix or blend.” The idea behind the Raleigh Misceo Trail 2.0—a flat-bar, 700c bike decked out with disc brakes and a suspension fork—is to blend the performance and versatility of a mountain bike with the comfort and street-friendliness of a hybrid. This machine is designed to tackle a variety of terrain, including pavement, rough roads and even dirt trails.Tweet
The Co-Motion Divide’s rugged looking frame is hand-built in Oregon using oversized Reynolds 725 chromoly tubing. Co-Motion’s tandem expertise is evident in the massive chainstays and the 40-spoke wheels, built using DT-Swiss 540 tandem hubs (with 145mm rear spacing for a dishless wheel) and Velocity Cliffhanger rims. The stout 44 mm-diameter head tube on the Divide is another clue that this bike means business.
The Divide rode like it meant business, too. As soon as I got her built, I zipped through the mean streets and hit the local trails. The bike felt incredibly stiff and well built. I took that as an encouraging sign for the loaded tour that lay ahead—a 355-mile self-supported tour along the unpaved Great Allegheny Passage and C&O Canal Towpath from Pittsburgh to Washington, D.C.Tweet

Raleigh told me that the Misceo Trail 2.0 is a city bike that can take a beating, and handle some light hard-pack trail use. Sweet! That sounds like a bike that fits my riding style. Let’s take a closer look at the $800 Misceo Trail 2.0 and find out what this versatile machine has to offer.
The Misceo Trail 2.0 rolls on 700c wheels. That’s the logical choice, for a fast-rolling city bike. Kenda’s Happy Medium 700cx38c tires have a center section that’s patterned with minimalist knobs. More-aggressive lugs line the outer edges (for cornering grip in loose conditions). The tires roll quietly, and I’ve been impressed with their traction on dirt. On a $800 bike you don’t get a fancy wheelset (Weinmann XM260 Disc rims laced to Joytech disc hubs). But the proof is in the pedaling, so I’ll reserve judgment until I see how the wheels hold up to longer-term testing.
Flat bars offer a comfortable riding position, and they’re the ticket when venturing off-road. The head-ups posture also makes it easier to scan the surroundings (i.e. traffic). My personal city/road bikes are set up with flat bars. That’s how I roll.
I like the concept of a suspension fork on rugged city bike. For a number of reasons: potholes, bridge expansion joints, curb drops, railroad ballast, gravel roads, rumble strips, and singletrack shortcuts. Offering 63mm of coil-sprung travel and a lockout lever, the SR Suntour NCX fork is not a high-performance mountain bike suspension. It doesn’t have to be. It just has to soak up the aforementioned irregularities. And so far it has been working just fine.
Beyond the suspension fork, the oversized fame tubing is another clue that this bad boy is ready to rumble. I couldn’t resist heading for some rocky/bumpy terrain to get a feel for the bike under strain. The aluminum alloy frame felt reassuringly solid and up to the task. More off-road testing is definitely in order.
Disc brakes are de rigueur for bikes of this ilk. For that, I am happy. The Shimano 416 mechanical calipers and 160mm rotors offer impressive of stopping power with good modulation, wet or dry. I’m about three weeks into this test and the brakes only squealed once (in wet conditions, and very briefly at that.)
The Shimano Alivio 3×9 drivetrain (with Deore rear derailleur) offers plenty of gearing range, which is quite welcome in my hilly hometown. The Wellgo M21 pedals, with their aluminum alloy body/cage, are keepers. The rear dropout has an eyelet for rack/fender mounting.

You may have noticed that the world of bicycle lights has quickly become dominated by LED technology. These little wonders are different from regular incandescent light bulbs, and superior in many ways, but there were some challenges to making them work for bike use. Read on to get educated.
What is a light-emitting diode?
A light-emitting diode, or LED, is a semiconductor device that produces light when an electrical current passes through it. While the light-emitting properties of semiconductor materials were noted as early as 1907, the phenomenon remained a curiosity until the solid-state electronics revolution led to the creation of the modern LED in 1962.
The LED is a variety of the ubiquitous semiconductor diode—the basic building block of modern electronic components and integrated circuits. In simplest terms, a semiconductor diode consists of a P-type (positive) semiconductor region joined to a N-type (negative) region. (Follow along with the diagram below.) The N-type region contains negatively charged free charge carriers (electrons) and the
P-type region has positively charged free charge carriers (electron holes). When current flows through the diode, the electrons and holes travel in opposite directions.
The magic of the LED happens at the P-N junction. When an electron meets a hole, the electron falls into a lower energy level (from conduction band into valence band) and releases energy in the form of a photon. Viola, light!
The wavelength of light emitted, which determines its color, depends on the difference in energy level between the conduction band and the valence band (i.e., the band gap). Suffice it to say that over the years a huge amount of research has been devoted to developing P-N junctions with the desired band gaps to produce light at useful wavelengths.
LEDs have a number of properties that make them well-suited for bicycle lights. They are compact, efficient, rugged, long lasting, and controllable.
LEDs have lifespans up to 50,000 hours or more, and their solid- state nature gives them inherent shock resistance that’s much appreciated for bicycling applications. Unlike incandescent bulbs, they have no filament to break.
The light output of LEDs may be modulated via relatively simple control circuitry, resulting in lights that offer user-selectable output levels. Fast switching times, on the order of a microsecond, make LEDs ideal for use in flashing mode.
LEDs boast efficiencies around 70 lumens of light per watt of energy, compared to 12 lumens/watt for incandescent light bulbs. Buoyed by continuous progress within the semiconductor industry, the efficiency and light output of LEDs has doubled every three years since the 1960s. This observed trend has been called Haitz’s Law, after Dr. Roland Haitz (similar to Moore’s Law, which states that the number of transistors on integrated circuits doubles approximately every two years, thus rapidly boosting computer processing speed and memory).
Visible-light LEDs generate very little infrared radiation in their light beam; in practical terms they do not exhibit a significant “heat lamp” effect, unlike incandescent bulbs, which convert around 80 percent of electrical energy into infrared radiation (and thus heat). LEDs do generate heat due to inherent inefficiencies, just like other lights, but the heat is dispersed through the base of the LED.
LEDs in bicycle lights
Since early LEDs emitted red light, naturally they found a home in rearward-facing “blinky” lights for bikes. It wasn’t until 1995, however, that an LED that produced white light was developed. After that, it took a few years for lighting manufacturers to figure out how to use these white LEDs to light the way for bikes. There were several issues to solve: heat buildup, optics, and power management.
First of all, heat. Although LEDs don’t produce a “heat lamp” effect, they do build up a significant amount of heat at their bases. Mike Ely, Vice President of Sales and Marketing for NiteRider, explains: “As you apply more power to the LED the brighter it gets, but it also generates more heat, and too much heat will destroy an LED very quickly. The way we manage this heat buildup is through heat sinking. The goal is to pull as much heat away from the LED as possible, brighter light output.”
A heat sink is a structure that dissipates heat, such as the metal fins or grooves you often find on a light’s housing. “The problem with this,” adds Ely, “is that as you add heat sink, you are increasing the weight and size of your light head. So in the early days of LEDs, due to the relative inefficiency, we couldn’t get the light output that we are seeing today. The key is to find the ‘sweet spot’ between light output and heat buildup.”
Second, the optics of an LED is very different from those of a light bulb. Daniel Emerson, CEO of Light & Motion, explains: “Bulbs suspend the [light] source out in space where it is easy to wrap a highly engineered reflector around it and direct the light. Look closely at a halogen bulb used in your home. Note the faceted, parabolic reflector around it with the bulb jutting out into the center. Now compare that with an LED, which is hidden behind a spherical dome and lays flat on a circuit board. It is much harder to build a good optic to support the LED than the bulb.”
Third, power management. “LEDs require very accurate voltage to run efficiently,” says Emerson. But “batteries are extremely poor at delivering constant voltage. So we need to design a circuit that makes up for the lousy voltage regulation of batteries.” This highlights one advantage of rechargeable systems, as the output of the batter- ies can be more tightly regulated so that the amount of light output stays the same whether the battery is freshly charged or nearly spent.
Despite these challenges, lighting manufacturers have made huge progress with LED lights in a short amount of time—they’re rapidly getting smaller, more powerful, and more efficient, while not increasing much in cost (and in some cases, actually getting cheaper). According to Emerson, LEDs “are now delivering over 150 lumens per watt, or double what they could deliver just a few years ago. In the next few years, they will approach the theoretical max output in the low 200 lumens/watt range.” And the end is not yet in sight.
“As large LED companies such as Cree expand into residential lighting and pump large sums of money into R&D, I believe we’ll continue to see more advancements,” says Ely. The next frontier for huge leaps in light technology may be batteries. “Hopefully, car battery technology will push batteries to four times the capacity for rechargeable cells that we have today,” says Emerson. “There is interesting work occurring in nanotechnology that has the potential to give battery technology this type of big leap forward.”
A note on measurement
The relative power of bike lights, when they used regular bulbs, used to be measured in terms of wattage. However, wattage only tells you how much energy the bulb is consuming, not how much light it is actually putting out. The lumen is a more accurate unit, as it is a measurement of the visible light emitted from a defined source (like an LED) falling on a surface.
Candlepower is another unit of light measurement, less commonly used, that gives the amount of light from a source, measured at the source itself rather than on a surface.
Less scrupulous companies will list the lumens of their lights based on the theoretical output of the LEDs in it, not the measured output of a production light. But as we’ve seen, the actual output of an LED depends a lot on the way the light is put together. The true way to measure is with an expensive device that encloses the light in a perfect sphere to capture all the light emitted. If you encounter a bike light that claims an incredible amount of lumens for a bargain-basement price, just remember: if it sounds too good to be true, it probably is.

Co-Motion Cycles has been hand-crafting an eclectic mix of bikes from their digs in Eugene, Oregon, since 1988. In addition to a wide range of tandem offerings, the company offers single bikes in the road, cyclocross, touring, and city categories. Their menu includes both stock geometry and full-custom offerings.
The Divide is a recent addition to the line, and like the other Co-Motion models, the bike is a purpose-driven machine that was created in response to customer demand. Ever since the company released the 26-inch Pangea adventure touring bike, folks had been asking about a 29er version. Read our long-term review of the Pangea model here.
The folks at Co-Motion eventually got tired of saying “not yet,” and built a few custom adventure-touring bikes with 29-inch wheels. The idea was to create a 29er suited for touring on the miles of unimproved roads that beckon for exploration, with the added versatility of 700c compatibility for efficient paved-road touring. The first few custom builds were very well received, and Co-Motion decided the configuration deserved its own model designation and stock sizes. The Divide was born.
The Divide is purpose-built for adventure touring, and not simply a road frame with extra tire clearance and additional braze-ons. The custom drawn, butted chromoly tubing is unique to Co-Motion. The oversized main frame tubes and massive chainstays are designed to handle the abuse of fully loaded touring over rough terrain.
Beefy custom forks are another other feature that sets Co-Motion’s touring bikes apart. The steerer tube and fork crown are turned down from a single piece of hollow bar stock, in house, on a CNC lathe. The result is a stronger and more precise part compared to traditional two-piece steerers. The stout head tube on the Divide is another clue that this bike means business. The dropouts are also Co-Motion’s own design, made in house on CNC equipment.
The base price of the Divide with standard touring kit is $3,925. However, my test bike included a $250 upgrade from BarCon shifters to Ultegra STI, and a $225 up-charge for two-tone paint ($4,300 sub-total). The Tubus Tara front rack and Cargo rear rack (both 29er compatible) represent $110 and $120 up-charges respectively (for a grand total of $4,530).
My main reason for requesting the Divide as my test bike was a 355-mile loaded tour on the unpaved Great Allegheny Passage and C&O Towpath trails, from Pittsburgh to Washington, DC. I shed the stock Continental Race King 29×2.2in tires in favor of a pair of Continental Country Plus 700x42c tires—skins more suited to the anticipated trail surface. The cherry on top was a set of Planet Bike Cascadia 29er fenders, and I was ready to roll.
After pedaling 70lbs. of combined bike/gear weight for six days, over 355 miles of mostly-unpaved trails, I came away impressed with the Divide. My experience left no doubt that this is one solidly-built machine. I’ve never ridden a frame that felt as stiff as the Divide. There was no perceptible flex while pedaling, nor bouncing over rough roads, even when fully loaded.
The C&O Towpath has some washed-out sections, and I soon discovered that I could plow into potholes with no fear. Sure beats having to constantly steer around them, especially when they come in rapid succession. And when I did need to make a quick course correction, the Divide responded nimbly enough, while still feeling comfortably stable. No shimmy and no shake. No wiggle, no waggle. Rock steady, mon.
If the 28.3 lbs. base weight of this bike (sans pedals) seems high, I’d argue that it makes perfect sense if you want a bike that can handle loaded touring over rough roads and not bat an eyelash. And the Avid BB-7 Road disc brakes did a fantastic job of controlling a full load, even on steep hills (did I mention there’s a C&O Towpath detour that forces you onto 6-miles of paved road that’s rather hilly?).
That’s all I have to say at this point. In the meantime be sure to subscribe to Bicycle Times to read my full review, scheduled for issue #21.

I have a knack for doing things the hard way. Even my vacations tend to morph from much needed rest and relaxation into masters-level exercises in logistics. As I type this blog I’m in the midst of preparing for a week-long, self-supported bicycle tour along the Great Allegheny Passage and C&O Canal Towpath trails with my riding pal Kevin.
The first thing on my vacation To Do List was getting a brand new Co-Motion Divide test bike (shown below) dialed in for the journey. Thanks to front and rear racks that Tubus was kind enough to provide, Brooks panniers that Bicycle Times previously reviewed, a swap of the stock 29er MTB tires for fresh Continental Country Plus skins and a set of Planet Bike Cascadia 29er fenders, my whip stands more than ready for the adventure. Look for my Co-Motion Divide "first impressions" blog in a few weeks, after I return from trip.
Next up was setting up Kevin, who owns two mountain bikes but nothing built for touring, with a suitable bike. My old Gunnar Crosshairs "cyclocross" bike to the rescue. The Crosshairs was long ago retired from the race circuit. Saddled with fenders and front/rear racks, the former thoroughbred now romps in greener pastures with the other grocery getters. The biggest challenge, and object of late-night wrenching in my dingy basement, was converting the Gunnar from drop to flat bars.
Kevin was just not comfortable on drops, and I was willing to make the switch, figuring that flat bare would better suit the bike’s current lifestyle anyway. It is amazing what some scrounging and cursing can accomplish. I unearthed some 9-speed Shimano XT brake/shift levers that I was able to get to play well with the Tiagra triple drivetrain (with less muss/fuss than I’d anticipated). The result is shown in the photo below.
Then there are the logistics of the trip itself. How far to pedal each day? Where to grab our meals? Where to camp? As I type, we’re about a week and a half from blastoff, and we’ve managed to sort out the aforementioned logistics. Not to mention rounding up the camping gear we’ll need.
Tell your story
However, there is one final task with which I’d like to ask your help, dear reader. In an effort to make this vacation even more like work, Kevin and I plan to shoot photos and video, with the goal of documenting the life and times along the Great Allegheny Passage and C&O Canal Towpath trails. If you have a story about life along the trails, historical landmarks, the best scenic vistas, or would like to share your experiences pedaling on the trail, please use the web form at this link to tell us your story. Our goal is to create a unique documentary film and/or published articles about the trail corridor.

When asked to describe the idea behind the Bosanova, Greg Webber, the vice president of product development at Jamis, had this to say: “Our Pacific Northwest retailers had been asking us for a rain bike: steel-framed, disc-brake equipped, drop-bar road bike (with fenders) for foul weather commuting and/or training that would retail for less than $1,500.” To make a long story short, Jamis mated the touring/ adventure geometry of their Aurora with their racier Quest model and begat the Bosanova.
I found that the resultant all-around geometry worked well, considering the bike’s versatile intentions. The Bosanova felt stable and held its line through high-speed corners. Still, it dodged potholes and responded quickly when pressed. Yes, a bike can be responsive without being twitchy-fast.
Fitting/adjusting the stem height was a breeze, thanks to the NVO adjustable threadless system, which replaces the typical spacer stack with a special shim that slips over the steerer tube, and uses a stem that’s sized to fit over the shim. Simply loosen the stem bolt, slide the stem up/down on the shim to the desired height, and retighten.
Adorning the double-butted chromoly frame are painted-to-match steel fenders and Avid BB-5 cable-actuated disc brakes. From my first rainy-day commute, I fell in love with the stopping power of the disc brakes. The fenders covered enough of the wheels to deflect the vast majority of spray, though my piggies did get a wee, wee wet on the way home.
Jamis positioned the rear fender and rack eyelets such that they don’t interfere with the disc brake caliper. I easily mounted a rear rack with no special adapters required. The chainstays proved long enough to provide heel clearance for my 14”-wide rear panniers. With loaded rear panniers, the Bosanova felt stable and predictable. I noticed some flex at the bottom bracket, but it was minor and I’d have no concerns about touring on the Bosanova. Overall, the Bosanova rode with the resilient and lively feeling that I’ve come to associate with a chromoly steel bike.
The carbon fiber fork has eyelets at the dropouts and mid-leg. I didn’t mount a front rack, but Jamis told me that the load limit for the fork is 30-35kgs. On rough roads, I noticed some fore-aft fork-leg flex, which helped absorb some road vibration and soften the ride.
The mostly-Shimano-Tiagra drivetrain came with a 12-30-tooth cassette and sported a FSA Vero triple crankset with PowerDrive BB (50/39/30-tooth). The triple crank contributed to the bike’s versatility, and I loved having the lower gears whenever hauling a load. Gear changes were smooth and reliable, albeit not as crisp/ quick as higher-end Shimano 2×10 offerings.
On the recreational end of the spectrum, I enjoyed the bike’s smooth, comfortable ride during multi-hour jaunts on both paved and unpaved country roads. It was a snap to slam that adjustable stem down and get into a more aggressive position when I felt like hammering out a training ride.
The Vittoria Randonneur Cross 700x28c tires offered plenty of grip over hard and soft surfaces, and rolled plenty fast. I mounted 38mm tires and found ample frame/fork clearance, with just enough fender clearance to do the trick. Jamis told me that, without fenders, the bike will fit tires as wide as 42mm.
If you’re looking for an affordable, utilitarian road bike that’s versatile enough to serve as your everyday commuter, and stands ready to emerge from a nearby phone-booth and tackle a weekend filled with adventure, then the Bosanova deserves to be on your short list.

A public-private coalition in the greater Philadelphia area is working to create a network of bicycle/pedestrian trails that, when connected, will be the nation’s most comprehensive metropolitan trail system.
Dubbed "The Circuit", the network will be formed by creating new trail segments that interconnect the 750 miles of trails that already exist, from southern New Jersey to central Pennsylvania. Not only a boon to bicycle commuters, The Circuit will also offer longer-distance recreational routes, and a connection to the East Coast Greenway—a developing traffic-free trail system between Canada and Key West, Florida.
Behind the effort is the 17-organization Circuit Coalition—a collaboration of foundations, governmental agencies, non-profits, and the private sector. To date, the Coalition has scored a $23.2 million TIGER grant from the U.S. Department of Transportation for trail construction, $5 million in federal stimulus funding for the Chester Valley Trail, and a $10 million grant from the William Penn Foundation toward trail construction and planning for dozens of trail projects throughout a nine-county region.
The Coalition recently launched a website that has maps and information on the trail network and allows users to share their favorite routes and to get involved in completing the trail network.Tweet

The Sea Otter Classic has traditionally been more associated with mountain biking than city riding, but we spotted a ton of cool stuff that translates to commuters and road riders as well.
Raleigh Tripper: Due out in July, the Raleigh Tripper is a three-speed city bike based on the same steel frame as the popular Roper and Furley models. The drivetrain sports a Shimano Nexus hub and disc brakes. Bicycle Times is at the front of the line to get a review sample, so stay tuned.
Lezyne Femto Drive LED light: The Femto Drive is a compact "be seen" LED light, due out in fall 2012. Available in a 15 lumen front (white) and a 7 lumen rear (red) version, the Femto Drive will retail for $15 each, or $25 for a F/R pair. The body is weather-resistant CNC-machined aluminum. Run times vary from 25-70 hours on the CR2032 battery, depending on which of the four pulse/flash modes is used.
DZR Dirt Line: Shoe-maker DZR is about to drop their all-new Dirt Line of SDP-compatible mountain bike shoes. Both the high-top Samba and the low-cut Dice retail for $120, and feature good-old laces covered with a Velcro strap to keep them out of harm’s way. Look for them to hit the shelves about two weeks.
Mission Workshop Rail Pack: Also due out in two weeks, Mission Workshop’s Rail Pack features the company’s Arkiv rail system which allows the user to modify and adapt the carrying capacity of their pack by attaching modular, external compartments that slide on/off the main body via a clever rail system. The whole package looks very smart and sexy. We’ve got one of these bad boys on the way for a thorough Bicycle Times review.
Feedback Sports Sprint bike stand: Due for June 2012 release, the Sprint is the first fork-mount bike stand from Feedback Sports. The cleverly designed fork mount works with 9mm/15mm/20mm front axles (as well as 130/135/142mm rear). The open design of the BB-cradle provides easy access to BB-routed cables. The 360-degree pivoting design makes it easy to rotate the bike and work on either side without moving. MSRP is $275.
Element Case: Now that you’ve got that new iPhone, how’s about a snazzy CNC-machined and anodized case to protect it? That’s the idea behind Element Case, the brainchild of industrial designer (and former Fox Racing Shox employee) Jeff Sasaki. Element Cases are made in the USA and available in a number of models ranging from $50-100, depending on features. They even do custom graphics, such as the Syndicate models shown in the photo.

Different riders have different riding styles. Each person gravitates toward certain types of bikes that meld with their style. When it came time to outfit myself with a test bike, the Jamis Bosanova rocketed to the top of my charts. I was attracted to the Bossanova’s versatile, utilitarian nature. It’s short list of attractive features: full-coverage fenders, disc brakes, drop bars, triple crank, steel chassis, practical tires, and rack eyelets.
Steel is versatile and practical. I like steel. The Bosanova’s chasis is made from Reynolds 520 double-butted chromoly main tubes and chromoly stays. The Bosanova rolled down the road with a resilient and lively feeling. When pulling hard on the bars, or mashing the big ring, frame flex was well within acceptable limits.
The frame/fork both have eyelets for racks, a nod to the bike’s versatility. Speaking of the fork, it’s a carbon fiber unicrown affair with steel steerer and forged dropouts. The fork looks stout, but did not harsh out the ride. Actually, it seems to kill some of the buzz from rough roads.
For the geometry Jamis chose a middle-ground between quick/racy and stable/touring. The all-arounder geometry resulted in a bike with comfortable and intuitive nature. The handling felt stable and predictable, without feeling at all sluggish. Pointed downhill, the Bosanova held its line and carved high-speed sweepers without wavering. When called upon to dodge potholes or dice in traffic, the Bosanova was quick enough to comply without complaint. The term "well-behaved" comes to mind.
Sporting painted-to-match metal fenders and disc brakes, the Bosanova is wet-weather capable. On minor complaint is that there’s some rattling coming from the rear fender, which I need to see if I can isolate and fix. My first rain ride sold me on the concept of disc brakes on road bikes. Wet braking power and modulation of the Avid BB-5 cable actuated discs was confidence-inspiring. Gotta love one-finger braking in the rain.
Rolling on Vittoria Randonneur Cross 700x28c with Double Shield puncture protection, this rig has been more than up to the task of tackling the mean streets and dirt roads. The full-coverage fenders shielded the stock tires perfectly, but it appears from eyeballing the fender-to-tire clearance that you’d run out of room pretty quickly if you tried to fit much wider tires.
I like having a bike with a triple-crank in my stable, so the Tiagra triple gets my thumbs up. I should point out that Jamis speced an FSA Vero triple crankset (with FSA PowerDrive bottom bracket), so the drivetrain is not full Shimano.

If you’ve been paying attention, you’ll have noticed a resurgence of simple, reliable bikes designed for short-haul transportation. Linus Bikes of Venice, California, offers just such a lineup of basic-transportation bicycles that take their styling clues from classic French bikes of the 1950-60s and utilitarian Dutch city bikes. According to Linus Bikes’ founder Adam McDermott, the Roadster 8 is “an all-around city bike, intended for everyday use and utility.”
The Roadster exudes a classy retro vibe. I especially like the way the painted-to-match metal fenders unify the look, from stem to stern. On a practical note, there’s nothing like full-length fenders to keep you singing in the rain. With the 8-speed gearing tucked inside the rear hub, the silhouette is clean and uncluttered. The alloy rear rack lets you know that this steed has some workhorse in its bloodline. Utility indeed.
With the traditional quill stem, it was a snap to adjust the handlebar height. I opted for a body position with a slight forward lean, as opposed to bolt-upright. I felt well-balanced, over the center of the bike, and in a “heads-up” posture where I could keep my eyes on traffic and the road ahead.
From the first ride, I noticed the Roadster’s decidedly quick steering response. Snappy steering makes perfect sense on a bike built for slicing through city streets. The only time that the quick steering felt out of place was going fast downhill—the bike wouldn’t toler- ate much steering input before things turned twitchy. Under said conditions, the bike be- haved better if I steered with my hips, or via some body lean, rather than with the bars.
The Shimano Nexus 8-speed drivetrain provided ample gearing for conquering my hilly surroundings. Only on the steepest grades did I have to get out of the saddle. When I did stand on the pedals, I was pleased to find that the wide handlebars were far enough out in front of my lap to provide sufficient leverage.
The 4130 chromoly steel frame and fork responded to hard pedaling efforts with the lively, efficient feeling that I’ve come to expect from quality steel steeds. No wasted effort, thank you very much. My definition of “lively” includes the fact that the bike let me feel the road, without having the road beat me up.
The Roadster 8 was the perfect horse for the five-mile course to the office. It was a breeze to click my pannier (filled with daily needs) onto the rear rack, retract the included kick- stand, hop aboard, and pedal—rain or shine.
The Roadster handled my grocery run, also about five miles each way, with ease. A pair of panniers loaded with provisions was well within this steed’s capabilities. The load barely affected the bike’s handling, and the Tektro dual pivot caliper brakes kept everything under control on the way downhill.
Linus did an admirable job of outfitting this bike with solid components, and not sneaking any zingers in there. I was impressed with the great traction (wet or dry) and smooth ride offered by the Schwalbe 700x32c Delta Cruiser tires (with reflective sidewalls). I enjoyed the real leather grips and comfortable leather-covered touring saddle. The bolt-on 36-spoke wheels (remember to carry your 15mm tool) were nondescript, but to their credit were built using double-wall alloy rims. I’m a bell person, so I’m giving Linus bonus points for spec’ing a sweet metal bell.
The $839 asking price seems appropriate, considering that the package includes a tried and true Shimano 8-speed drivetrain, solid components, metal fenders, and an alloy rack. Available in cream (tested) and black, the Roadster is a fun-to-ride looker that’s perfectly suited for the daily grind.

Sherman, set the Way-Back-in-the-Day Machine to the year 1981, and the place: Phoenix, Arizona. The objective of our mission: the Belt Beacon.
During a recent basement-cleaning session, I stumbled upon my Belt Beacon, the first flashing bike safety light that I ever purchased. I was living in Phoenix at the time, and to the best of my knowledge the year was 1981. I can’t remember if other "blinky" lights were widely available at that time, but a friend recommended the Belt Beacon, so I ended up purchasing one.
As you can see from the photo at the top of the page, the Belt Beacon is a behemoth by today’s standards, eerily reminiscent of a motorcycle tail light from the same era.
Despite it’s awkward form factor, the Belt Beacon gave me years of reliable service before it stopped working. I tried to trouble-shoot the circuit, but my limited electrical engineering skill were not up to the task. I can’t bring myself to toss it out. Perhaps, one day, I might solve the mystery and resuscitate this piece of history.
The photo above shows the unit with the translucent orange plastic cap popped off, and reveals the high-intensity lamp that gave Belt Beacon it’s retina-searing brightness. Even by current standards, this baby was bright! And the dome-shaped cover provided great side-visibility to boot.
The black mark and scar at the six o’clock positon on the orange cover was caused by my rear tire rubbing on it. I recall that I had mounted the Belt Beacon on my rear rack’s reflector bracket. Somehow the bracket got bent, causing the cover to drag on my rear wheel. I can’t believe it wore such a deep groove before I noticed. Oops!
The photo above shows the rear of the unit. A small, black on/off switch is located at the six o’clock position. The screw and washers at 12 o’clock were used to attach the Belt Beacon to the reflector mount.
You can also see two diagonally-opposed mounting holes (at 4 and 10 o’clock) that, along with a pair of provided screws, were to be used for mounting the Belt Beacon to a fabric strap, or a backpack, or a wide fender. I never used that attachment method.
The slot at three o’clock in the photo was used to attach a provided metal belt-clip, which was designed to be worn: "on a belt, head sweat band, or hung over any convenient object," according to the instructions (yes, I kept them). The belt clip worked well, as I recall. It went MIA at some point.
The instruction sheet includes the following passage: "Motorists, especially inattentive, tired or intoxicated, are a real danger to hikers and bikers who travel at night. Your real safety, in the absence of good paths, depends on being highly visible and getting motorist’s attention. Your solid state Belt Beacon electronically drives a high intensity lamp, and does so at low cost with high portability and exceptionally long battery life."
The warning about "inattentive, tired or intoxicated" drivers still rings true today. Sadly, the streets haven’t gotten any safer in the past 30 years.
Another paragraph from the instructions has this to say: "Backpackers, hunters, airplane pilots and night fishermen will find the portability and long battery life make the Belt Beacon a good addition to their usual kits. If lost or an emergency arises, the Belt Beacon will flash strongly approx. 1-2 weeks or more at night."
True story: the Belt Beacon saved by bacon on one particular "power-boat camping" trip. I used it to illuminate my remote camp-spot at night while I motored back to the docks to pick up a late arriving friend. Using the Belt Beacon as a signaling device on the shoreline was most likely highly illegal, but If it weren’t for the bright strobe indicating my remote camp spot, I’d probably have run out of gas looking for my camp in the dark.
I was able to track down some Belt Beacon history via Cyclelicious who indicated that the Ampec company from Phoenix started selling the Belt Beacon in 1974, and stopped making them in the late ’90s. That’s right about the time that LED safety lights burst onto the scene. The folks from Cateye tell me that they introduced their first LED blinky in the USA in 1992.
Let’s hear from you. What’s your earliest recollection of blinky lights? Which model did you first purchase? Do you remember the Belt Beacon? Please comment below.
This mileage signpost along the GAP in Connellsville, PA sums up the dream quite succinctly.
By Karl Rosengarth
It’s fantastic how a simple vision can inspire great accomplishments. Case in point: the simple vision of a bicycle trail connecting Pittsburgh, PA to Washington, DC.
The first part fell into place in 1971, with the establishment of the C&O Canal National Historic Park, which offers 184.5 miles of non-motorized adventure from Cumberland, MD to Washington, DC.
I’m not sure how long after 1971 it took for people to start dreaming about a trail connecting Pittsburgh to the C&O trailhead, but dream they did.
That dream eventually became reality, in the form of the Great Allegheny Passage (i.e., the GAP), a 150-mile system of trails running from Pittsburgh to Cumberland, mostly along relatively-flat, abandoned railroad grades.
I picked the terms "vision" and "dream" carefully, because the story behind the GAP is a tale of a shared vision, a dream, that became a rallying cry.
"What if you could ride your bike on trails all the way from Pittsburgh to Washington, DC?"
That vision was the dream that rallied grassroots efforts all along the GAP trail corridor and inspired the cumulative, indefatigable efforts of non-profit organizations, local governments and dedicated individuals who fought, and won, mile-by-mile battles to string together the GAP.
I am one such individual. In 1991 I learned that a volunteer group was being formed to convert an abandoned rail corridor, along the northern section of the Youghioghenny River, into a rail-trail. It wasn’t the concept of a building a 40-mile scenic bike trail that inspired me to get involved. It was the dream of riding a trail that would one day stretch from Pittsburgh to Washington that provided the inspiration.
That grand vision motivated me to attend an organizing meeting, and eventually get myself elected to the Mon-Yough Trail Council’s inaugural Board of Directors. The volunteer efforts of that organization helped convert a decaying, abandoned railroad into a beautiful crushed-limestone trail within Allegheny County, the county that encompasses the city of Pittsburgh. I’m proud to have played a small part in creating the legacy that is the GAP.
Since 1991, I’ve spent countless hours, riding various sections of the GAP in and around Pittsburgh. While I haven’t yet pedaled all the way from Pittsburgh to Washington, I did complete a 267-mile self-supported tour along the GAP and C&O Towpath from Somerset, PA to Washington, DC. The whole Pgh-DC enchilada is sill on my bucket list. Perhaps 2012 will be the year?
How does this story relate to Pittsburgh’s past? Well it turns out that George Washington shared a similar vision.
According to the Potomac Heritage National Scenic Trail website: "George Washington’s dream of connecting the eastern states with the western frontier led to the creation of the Patowmack Company. Locks were built around unnavigable parts of the Potomac River for improved commerce."
Yep, old George had major role in the creation of the C&O canal. Washington’s desire to develop a corridor between the developed eastern cities and the western frontier (and specifically the Ohio Valley) drove him to explore the very the route that the GAP follows today. The route played a key role in our country’s westward expansion.
And, as I pointed out in part one of this series, it was the strategic location at the Ohio River headwaters that eventually led to the founding of the city of Pittsburgh.
Just about every time I pedal along the GAP, I find myself daydreaming of George Washington, and the other pioneers, who explored the region in days gone by. Pedaling Pittsburgh’s past, to be sure.
The 1,908 ft. long Salisbury Viaduct crosses the Casselman River valley west of of Meyersdale, Pa.
In Allegheny County, near Pittsburgh, the GAP offers this stout bicycle and pedestrian bridge over the Monongahela River, a re-purposed railroad bridge connecting Duquesne and McKeesport, Pa.
This ramp on a bicycle pedestrian bridge near Duquesne, Pa., (over active railroad tracks) gives riders an increasingly-rare view of the Pittsburgh region’s steel-making heritage.
The GAP crossed the Youghioghenny River at scenic Ohiopyle, Pa.
Cyclist of all sorts ride the GAP (Connellsville, Pa.).
The GAP rolls right by the confluence of the Youghioghenny and Casselman rivers, at Confluence, Pa.
The GAP offers access to many beautiful "beaches" along the Youghioghenny River. Great for cooling off on a hot day, or accessing that favorite fishing hole.

I’m a man on a mission, for better traction. This year at Interbike I roamed for rubber. What follows is a selection of tires that piqued my interest. Note that some of the tires listed are not yet released; therefore, full specs may not yet be available.
The Maxxis Gyspy touring tire looks like a great choice for commuters, as well as loaded tourers. The dual compound construction provides harder rubber down the center for longer wear, and softer cornering rubber on the sides. Available in both 700 x 38c and 26 x 1.5" sizes. Price TBD. www.maxxis.com/Bicycle.aspx
Continental’s TopContact Winter II tires have abundant micro-siping designed for maximum grip in wintry conditions, without the need for metal studs. The tires feature a 3M reflective stripe on the sidewalls. They retail for around $65 and are available now in both 700 x 37c and 26 x 1.9" sizes. Let it snow! www.conti-online.com
The new Kwick Tendril from Kenda is a city/touring tire with a smooth, fast-rolling, center section. The outer, cornering surfaces have siping and a knurling for improved grip. Available in a wide range of 700c widths from 25 through 38c, and in 26 x 1.5 and 1.75" options. www.kendausa.com
Rando is all the rage. And if you really want to rock some street cred, then you’ll want to roll 650B. Panaracer has got you covered with their Col de La Vie, a 650B x 38mm tire with inverted tread design that’s well-suited for rando and/or touring duty. www.panaracer.com
Vee Rubber has been in the bicycle tire business for over 30 years, though they’ve had little presence in the US market as of late. That’s about to change as the company is releasing a complete range of mountain and road tires, starting in October 2011. Their Easy Street commuter tire will retail for around $20 in wire bead. Available in various widths in 700c, 26" and 28" sizes. veerubberusa.com
Schwalbe’s all-new Marathon Mondial is and adventure touring tire that’s available in a variety of widths in both 26" and 700c sizes. These bad boys feature harder compound down the center for longer wear, softer compound on the sides for improved cornering grip, SnakeSkin sidewall protection, and a woven aramid belt for puncture protection. www.schwalbetires.com

Freedom is expanding their Cruz tire lineup in 2012 to include an all-new 29 x 2.0" size. They’ll be out in October 2011 and will retail for around $33 (wire bead only). Great news for commuters rolling to work on 29ers or monstercross rigs. www.freedombicycle.comTweet
The Ridekick power trailer is an interesting twist on electrifying your ride. Thanks to its built-in 500 Watt electric motor, this battery-powered trailer gives a boost to your existing bike. Last year we tried a pre-production version, and now the finished product is on sale.
The $699 trailer has a clamshell design that provides 41.8 liters of enclosed cargo space. Rated hauling capacity is 75 lbs. The hitch attaches through the left-side Q/R skewer.
The current version of the Ridekick uses a sealed lead-acid battery and has a range of 12-15 miles. Ridekick is working on a lithium-ion battery upgrade that will expand the range, though exact specifications are not available at this time.
A simple handlebar-mounted thumb-lever serves as the throttle. On my test ride I found that having to thumb the throttle was not as convenient as "just pedaling along" the way I would on a pedelec, but the throttle got the job done nonetheless. The Ridekick had plenty of guts and flattened out the uphill grades. There was a slight surgieness in the way that the trailer delivered its power to the bike compared to rear-hub motors, but for $699 the Ridekick is an affordable and effective way to boost your bike.
It doesn’t end here, we’ve got a lot more coverage of Interbike 2011.
A redesigned battery is 100g lighter and offers increased capacity, boosting the range from 50 to 60 miles. The handlebar-mounted control unit has been redesigned with a more intuitive interface/display (the functions remain the same).
The new battery includes a 6-volt power output jack for connecting a lighting system. Charging control circuitry is now built into the battery itself, and the previously-required smart charger is replaced by a simple, more compact charger.
My test ride confirmed that the updated BionX system offers the same seamless pedelec power and snappy performance as the original. The retail price for the 350 Watt system is $1,899 with a downtube mounted battery or $1,999 with rear rack mounted battery.
It doesn’t end here, we’ve got a lot more coverage of Interbike 2011.
Linus Bikes is on a mission to provide simple, reliable bikes that take their styling clues from classic French bikes of the 1950-60s and utilitarian Dutch city bikes. According to Linus Bikes‘ founder Adam McDermott, the Roadster 8 is "an all around city bike, intended for everyday use and utility." Sounds good to me, let’s give it a whirl.
The Roadster 8 immediately struck me as an eye-pleasing blend of retro-fashion and modern-day function. The painted-to-match metal fenders, give this steed all-weather practicality, and enhance its classical aesthetics. The high-tech bits are tucked neatly inside the Shimano 8-speed Nexus hub, where they are barely noticeable yet much appreciated.
The bike’s heads-up rider position is my preferred arrangement for pedaling in traffic. Steering response is notably quick, the way it should be on a bike built for slicing through city streets. Flat pedals make it convenient to hop on and run a quick errand. Leaning on its kickstand in my basement, the Roadster 8 is not snoozing, it’s in the "ready position," awaiting our next mission.
With a single pannier snapped onto the included alloy rack, the Roadster 8 has been just the ticket for commuting to the office and back. The eight speeds have flattened the hill-climbs on my 5-mile route to Bicycle Times HQ, and the Tektro dual pivot caliper brakes have kept things under control on the downhill side. I’ve yet to utilize the Roadster 8 for a major grocery run, but that’ll come in due time.
For the $830 asking price you get a 4130 chromoly frame/fork, outfitted the aforementioned items, plus the following noteworthy touches: Schwalbe 700 x 32C Delta Cruiser tires, real leather grips, and metal bell. The Roadster 8 is made in China.

Soma Fabrications of San Francisco, California is on a mission to produce practical, durable, comfortable and affordable products for the everyday cyclist. The Buena Vista is Soma’s mixte frameset.
The mixte design replaces the traditional top tube with a pair of smaller tubes that run from the head tube all the way to the rear dropout, with a connection at the seat tube. By retaining the conventional seat- and chainstays, the mixte provides generous standover clearance, combined with better structural rigidity than step-throughs with a dropped top tube. The mixte is also skirt-friendly, for those so attired.
I asked Stan Pun, the marketing and product development guy at Soma, about the target market for the Buena Vista: “We would like to say it is for anyone looking for a classy, quality ride. But it isn’t just a ladies’ or gentleman’s bike. We wanted to do a mixte that someone would not mind riding long distances with and feel at home riding fast on. We’ve had one enthusiast use it with an Xtracycle. The low standover allowed him to mount from the front, so he wouldn’t kick his kid in the head.”
To be sure, this is not your grandparents’ mixte. It’s made from Tange Infinity heat-treated chromoly for the down and seat tubes, and butted/tapered chromoly in the rear end. Chromoly is stronger than the plain steel used in many vintage mixtes (which have a reputation for being flexy), and can be formed into larger diameter, thin-walled tubes. Said tubes produce a stiffer frame with no weight penalty.
The Buena Vista comes with a lugged, sloping-crown, chromoly steel fork. The 132.5mm rear dropout spacing falls in between road (130mm) and mountain (135mm) hub spacing, and thanks to the steel frame’s inherent flexibility, it will accommodate either road or mountain rear hubs. Semihorizontal dropouts equal singlespeed compatibility. The frame is also ready for front and rear racks and fenders. Versatility indeed.
The Buena Vista was not specifically designed as a dedicated “townie” bike, and I’m told that the typical customer would opt for a “sport road/touring” build with drop bars. But when Pun offered to provide a townie build, I decide to accept, and put the frame’s versatility to the test.
My build sported a Sturmey Archer 8-speed drivetrain with twist shifters (see sidebar for more information). The frame will work just fine with derailleurs, and it even comes with down tube shifter bosses. My build included several “house” brand goodies including Soma’s New Xpress 28c tires in terra cotta (a personal favorite of mine) and Sparrow bar in 560mm width. From the photo, one can see the tall stack of headset spacers—visually awkward, perhaps, but they gave me ample stem height adjustability, very useful for tweaking my position.
From my first pedal strokes, I realized that this was one quick-handling townie. The narrow Sparrow bars combined with the 73º head angle produced a snappy feeling at the handlebars. The Buena Vista diced through congested city streets like a Ginsu knife. With the upright, head-on-aswivel riding position, I felt confident and in control when dodging potholes and/or avoiding collisions with aggressive bus drivers.
After receiving the Buena Vista, I’ve test-ridden a few other townie bikes, and they felt similarly snappy at the handlebars. We’re talking fast-paced city life here, not laid-back beach cruising.
Sturmey Archer recommends a 30-tooth chainring, but Soma built my bike with a 34-tooth chainring, which made my “easiest” gear (34×23) higher than normal. The narrow bars combined with the higher gearing gave me some grief on steep, long hills. After a few rides, I switched to wider mountain bike bars and twist-shift compatible Ergon grips with integrated barends to give me more leverage on the handlebars. Now that’s what I’m talking about! I was able to produce more oomph up the hills, and the handling was still plenty quick.
The Buena Vista was just the ticket for my weekly 25-mile-plus “explore the city” ride. On it, I rhythmically weaved through crowed streets in search of adventure around the next corner. At the other end of the spectrum, the Buena Vista felt comfortable and at home cruising the open, and sometimes unpaved, rural roads on my favorite multi-hour recreational loop. There’s that versatility theme again.
The Buena Vista exhibited the classical “lively” feeling of a quality chromoly steel frame—a sweet blend of snappy acceleration and a comfortable resilience over the road. I felt that the mixte design offered some additional bump-absorbing vertical compliance, compared to double-diamond frames.
Going into the review, I wasn’t sure what to expect from a mixte. Fortunately, what I didn’t get was any notable frame flex or feeling of lost efficiency. I felt comfortable pushing the Buena Vista hard into corners, hopping curbs, rumbling over unpaved roads, and generally riding without any inkling of “holding back.” Hey, it rode like a bike, imagine that!
At less than five bills for a chromoly frame/fork, the Buena Vista impressed me as a great value. It’s equally the ticket for the tinkerer looking for a versatile frame, or somebody with a set plan and a set budget. This steel is real—affordable.
