The light weight, magnesium Brose TF MAG motor produces 90Nm/66 ft. lb. torque, plenty of power assistance to provide a quick launch from a standing start and to give the rider the ability to conquer challenging hills. High performance thanks to a brushless internal rotar and mid-drive mounting


Gates™ carbon fiber drive belt is smooth, quiet, and maintenance-free; it requires none of the frequent lubrication or adjustment of a chain-drive system.

The revolutionary enviolo hubs feature rotating planets that, over the hub’s ratio range, permit an infinite number of ratios between incoming power (from the chain/belt through pedaling) and outgoing power (via the hub flanges to the wheel).As a result, damaged shift cables and maintenance to fix malfunctioning gears are a thing of the past. With the continuously variable transmission, cyclists will progress effortlessly from one gear ratio to the next, making pedaling a breeze!


  • Zero Shifting
  • Battery
  • 4 Modes

There is no shifting required – the intelligent technology automatically adjusts the gear ratio to maintain the rider’s optimal, personalized pedaling cadence as terrain or speed changes.

The RUSH/CTY SPEED has a battery that is 706Wh. Designed to be removable and give you a range of 25-115 miles depending on your mode and terrain. The battery can be quickly removed from the frame without tools and a key locks the battery into the frame for enhanced security.

Charge Time: 0-100% = 6.6hrs, 0-75% = 3.5hrs


An electronic torque sensor automatically registers the pressure the rider applies to the pedals and instantly provides a commensurate amount of electric assistance, greatly simplifying use for all riders. No throttle or other action required—just pedal and go.

Large tires allow for a more comfortable ride without worrying about suspension. RUSH/CTY SPEED is equipped with Schwalbe Super Moto-X 27.5 x 2.4-inch tires.


Ergonomically arranged thumb-and-forefinger controls on all models allow the rider to turn the eBicycle on and off, change ride modes, switch the integrated headlight on and off, and engage walk-assist without lifting a hand off the handlebar.

Vulcanised Natural Rubber Saddle Top, UV + Abrasion Resistant Waterproof Nylon Top & Flexible and Robust Touring Surface


Mid-mount placement near the crank lowers the center of gravity and centralizes mass to optimize vehicle handling.

Frame geometry is optimized for each frame size to maintain a comfortable riding position and consistent handling across all rider sizes, regardless of rider height. The desired riding posture for the city bikes is upright to maximize comfort and awareness of the rider’s surroundings. Both the frame geometry and contact points were evaluated, to make sure that our size range is well suited to nearly every customer.
