Tern debuts compact electric utility bike

This week, Tern launched the GSD, a utility e-bike that the company calls “category-defining.”

Tern states that “The GSD can haul two kids, a week’s worth of groceries or 180 kg (almost 400 lbs) of cargo.” But it’s a lot smaller than most cargo bikes, which tend to be highly unwieldy objects. If you have to put the bike in a small apartment or vehicle, forget it.

The GSD is actually no longer than a normal bike, so it fits on standard car or bus bike racks, and folds to reduce its height by one third and its length by 40 percent.




“One of our guiding insights was that cargo bikes are most useful in city centers, but they’re correspondingly difficult to manage and store,” according to Galen Crout, Communications Manager at Tern. “Dense urban centers bring cargo bikes to life–where groceries, schools and work are all within a bikeable distance–but they’re also where houses are small, and where bike theft is a persistent problem. We’re creating the compact utility e-bike category to let people in cities enjoy the benefits of cargo bikes without the limitations.”



The GSD is highly adjustable for a variety of different heights and sizes, and it’s meant for the whole family to be able to use. The cockpit and handlebars can be adjusted for reach, and low-step through and a low center of gravity make it easy for smaller riders to ride and handle.


The frame and components are meant to handle big loads, whether its two adults (one driver, one passenger), an adult and two kids, or plenty of cargo. The GSD rack is 80 cm (31.5 in) long and the included panniers fit a total of 62 liters.



The bike has room for two batteries that power a Bosch Performance motor, so the GSD can keep rolling for up to 250 km (155 mi) before needing to recharge.


The GSD comes with integrated lighting, fenders and panniers and will retail for $3,999.

Electric bikes are setting the cycling industry and community abuzz. Manufactures are excited about this “new segment” of the market and are quick to point out the virtues of electric bikes for facilitating commuting and a greener lifestyle, as well as bringing non-cyclists into the fold. The cycling community is quick to point out that, technically, electric bikes could be considered a motorized vehicle—it does have an electric motor afterall—and thus, shouldn’t be allowed on trails designated for human power only.

In reality, it seems both of these perspectives have merit. With this conflict in mind, I agreed to review Haibike’s XDURO Trekking RX. As a long-time cyclist, I went into this review siding most closely with the community’s skepticism. At the same time, the idea of having some assist during my 14-mile round trip commute this winter had a lot of appeal.

On my very first commute, it was clear my electric assist fantasy was every bit as good as I had imagined. Bosch’s sophisticated Performance mid-drive system used on this Haibike is impressively engineered with an easy-to-use human interface and smooth, reliable power output. The 350 Watt electric motor roughly doubles the output of the average in-shape cycling enthusiast, so it really is quite speedy. Speedy, at least up to 19 mph where the system begins to taper off assist prior to cutting out altogether at 20 mph.

Governing maximum assist speed to 20 mph has been a legislative maneuver to manage the small but growing demand for e-bikes. My home state of Pennsylvania recently legalized e-bikes for on-road use, utilizing the definition “pedalcycle with electric assist” in the process. What hasn’t yet been fully addressed is the legality of using e-bikes on non-motorized trails-to-trails-style trails.

At this point, it’s a little bit of a wild-west scenario. As I currently understand the situation, these regulations are to be made on a case-by-case basis by the locality with jurisdiction over any given trail. Most of these local entities haven’t yet ruled on the pedal assist issues since there has been little need to do so to this point, largely due to the limited number e-bikes currently in circulation.

But, as e-bikes like this become increasingly widespread, it will be interesting to see how these bikes are managed. After spending time on the Haibike, I’m convinced e-bikes can play a vital role in lessening our reliance on fossil fuels for transportation.
