THE OTIS

Speed Meets Agility. Built for City Streets.

Heavy bikes kill the fun. The Otis strips the weight to just 55 pounds—power-to-weight optimized for riders who want to drive the bike, not just cruise it. Naked and raw, without fenders or racks that slow you down. A high-performance 52V system paired with surgical tires that carve through city streets. Class 2 throttle for commute chaos, Class 3 pedal-assist for weekend exploration. You don't just ride it; you flick it through corners. Premium components. No apologies.
