The lightweight, mid-mounted Brose TF MAG motor features a brushless internal rotor and 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.

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

The fully enclosed, maintenance-free Enviolo AUTOMATiQ intelligent automatic transmission is an electronically controlled CVT (Constantly Variable Transmission) rear hub that automatically adjusts the gear ratio to maintain the rider’s optimal, personalized pedaling cadence as terrain or speed changes.



The RUSH/CTY SPEED is equipped with an integrated, 706Wh lithium-ion battery that can be quickly removed from the frame without tools. The battery locks into the the frame for enhanced security.

The integrated, removable, 706Wh lithium-ion battery delivers a real-world range of 25-115 miles, depending on ride-mode selection, terrain, and how much pedal input the rider supplies.

The lithium-ion battery can be charged on-the-bike through a charging port conveniently located on the frame downtube, or easily removed for off-the-bike charging. Charge times are as follows: 0-100% = 6.6hrs; 0-75% = 3.5hrs." Illustrate with a photo of the charger installed in the charge port.



Front and rear hydraulic disc brakes utilize four-piston calipers and 203 x 2.3mm heavy-duty brake rotors designed to deliver confident braking performance in most riding conditions. This is essential for faster-moving eBicycles and all-weather commuting." Illustrate with a photo of the RUSH/CTY SPEED brake system.

Wheels consist of 27.5 x 35mm alloy rims laced with stainless-steel spokes and fit with high-volume, 2.4-inch diameter Schwalbe Super Moto-X tires. The result is a perfect combination of low rolling resistance, ample shock absorption, and responsive, predictable handling." Illustrate with a photo of the RUSH/CTY SPEED wheel/tire combination system.

Front and rear fenders protect the rider from wheel spray when riding in wet or dirty conditions. Front and rear cargo racks increase utility and practicality, providing a convenient way to carry small loads." Illustrate with a photo of the RUSH/CTY SPEED fender/rack combination.

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.

Brake lines and electrical wiring are routed through the frame, promoting longer life and less maintenance through protection from the elements and clean, snag-free styling.
