The RUSH/CTY is a powerful, intuitive commuter that wins on hilly terrain. This version has an easy-access step-through frame. The hub transmission is automatic and motor is pedal-assist, so there's no throttle, no shifters, and no learning curve. Serial 1 simplifies the e-bike to power your commute.

- Step-through frame for easier mounting and dismounting
- Intuitive transmission automatically adjusts your gear based on terrain
- Motor has 4 modes and a neatly-integrated battery that tucks into downtube
- Belt drive is quiet and maintenance-free so getting on the road is easy
- Wide tires are comfy on any terrain from pavement to gravel to dirt
- Cargo racks and LED lights make this the ultimate daily tool
