Sea Otter Classic 2017: Alter Cycles

As I wandered around the Sea Otter Classic this year, a collection of unique-looking bikes all the way at the edge of the expo caught my eye. The noticeable difference between these bikes and most other bikes was the downtube—a curved arc replaced what is normally a straight piece of tubing.

As I stopped to take a closer look, one of the guys manning the booth came over and asked me if I’d like to take it for a test ride. I didn’t have time to go far, but I jumped on the bike and pedaled around the perimeter of the expo. It rode very smoothly—it turns out that the crazy-looking downtube actually acts as a type of suspension, absorbing shock from bumpy roads while also improving pedaling efficiency.

When I got back from my brief ride, I got the lowdown.

In addition to the curved downtube, which Alter Cycles calls the Rider Fit Tube, a specially-designed top tube provides vertical flex while minimizing horizontal movement. Together, the tubes flex as you pedal or encounter bumps.

Alter Cycles also claims that this design improves pedaling efficiency, storing power during the downstroke and releasing it at the bottom of the pedal stroke (normally the “dead zone”). I didn’t spend enough time on the bike to confidently attest or refute that this is the case.

There are four models available, all based around an aluminum frame and a steel Rider Fit Tube. The Reflex line offers three different hybrids with varying components. The top-of-the-line Reflex Elite 500 comes with a carbon fork, Shimano Tiagra and Tektro hydraulic disc brakes, while the budget-friendly Reflex Sport 100 is set up with a steel fork, a Shimano Altus 3×8 drivetrain and mechanical disc brakes.┬áPricing starts at $749 for the Reflex 100 and goes up to $1399 for the Reflex 500.

The Route 400 is a drop bar gravel and road bike featuring an aluminum fork, a Tiagra 2×10 drivetrain and Spyre mechanical disc brakes. It comes in at $1599.

The downtube is customizable, with seven different colors as well as a few patterns. There are also four different flex options of varying stiffness, allowing riders to tune the bike to work optimally for their weight and desired riding style.
