Why we carry it

Up the canyon and back

Button Rock Preserve is the reward at the end of a real climb, and the Button Rock is built to get you there with enough left in your legs to enjoy the descent.

Class 1 — pedal assist only, no throttle, 20 mph cap. That classification is deliberate: it is what keeps you legal on the majority of Boulder County trail systems where Class 2 and 3 are restricted.

140mm front and rear, a Bosch Performance Line CX making 85 Nm, and geometry borrowed from bikes that cost more than this one. It climbs like an e-bike and descends like a trail bike.
