Why we carry it
Commute without thinking about it
Union Reservoir is four miles from downtown and most people drive there. The Union exists so you do not have to.
Class 3 pedal assist means you hold 28 mph without redlining, which is the difference between arriving at work sweaty and arriving at work. A torque sensor reads how hard you are actually pushing and matches it — no lurching, no on/off surge.
We spec this one with a Gates belt drive. No chain, no oil on your pant leg, and roughly zero maintenance for the first few thousand miles.
Best for
Daily commuting, 5–15 mile round trips, all-weather riding
