MOTOR: 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
BELT: 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.
HUB: 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: 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.
BATTERY: 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
4 MODES: 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.
203mm DISC BREAKS: Hydraulic four-piston-caliper disc brakes front and rear, 203mm X 2.3mm “heavy-duty” rotors.
HYDRAULIC: Front and rear hydraulic disc brakes utilize upsized 203mm brake rotors designed to deliver confident braking performance in most riding conditions – essential for faster-moving eBicycles and all-weather commuting.
APP : A smartphone with the Serial 1 App, when paired by Bluetooth with the Serial 1 eBicycle, can operate as a secondary digital dashboard on both RUSH/CTY models or a primary digital dashboard on the MOSH/CTY model, which is not equipped with a digital display.. More info coming soon
4 MODES: Use the LED screen to control 4 boost modes. A 1.5-inch, 240 x 240-pixel TFT display shows selected ride mode, current speed, odometer/trip meter, battery charge level, and headlamp on/off status at a glance.
TIRES: 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.
HANDLEBAR CONTROLS: 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.
SEAT: Vulcanized Natural Rubber Saddle Top, UV + Abrasion Resistant Waterproof Nylon Top & Flexible and Robust Touring Surface
CENTER OF GRAVITY: Mid-mount placement near the crank lowers the center of gravity and centralizes mass to optimize vehicle handling.
INTELLIGENT SIZING: 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.
ELEVATED CHAINSTAY: The elevated chainstay is the raised part of the frame near the rear hub.
INTEGRATION : With features like signature front and rear lighting; internally routed controls; an integrated battery and mid-drive motor.
HEADLAMP: A BAF™ LED headlamp mounted on the handlebar stem illuminates the path ahead.
AUXILLARY: A distinctive LED front signature light pays homage to the shape of the classic headtube badge on Harley-Davidson’s original bicycles and illuminates whenever the eBicycle is powered up.
BRAKES: Bright LED tail and brake lights integrated into the frame dropouts are designed to make the bike more visible from the rear.
CARGO RACKS: Front and Rear cargo racks are designed to increase utility and practicality, providing a convenient way to carry small loads.
GLOVE BOX: A LOK-BOX™ in the RUSH/CTY, RUSH/CTY STEP-THRU and RUSH/CTY SPEED downtube provides a convenient place to stow a lock or other small items you might wish to take along for the ride.
MAINTENANCE: Maintenance Brake lines and electrical wiring are routed through the frame.
Protected from the elements to promote longer life and less maintenance. As a result, damaged shift cables and maintenance to fix malfunctioning gears are a thing of the past.
Fully enclosed enviolo™ gear hub requiring no maintenance for long term durability
