  • Light and strong hydroformed aluminum frame
  • Sleek, integrated batteries

Key Design and Technology Features:

Leveraging Harley-Davidson’s world-class product development capability and leadership in electric-powered vehicles, Serial 1 Cycle Company presents eBicycles guided by intelligent, human-centered design and crafted using the most advanced bicycle technology in the world.

Aluminum Frame: Frames and forks are constructed from welded hydroformed aluminum to be light and rigid, with geometry designed to deliver:

  • Nimble, agile handling in urban environments
  • Confident control and comfort on bicycle paths and rural backroads.

Integrated Battery: The lithium-ion battery is integrated into the lower frame for sleek style and convenient removal for off-the-bike charging. It can also be charged on the bike through a charging port conveniently located on the lower frame.

Mid-Mounted Motor: The Brose S Mag mid-mounted 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. Mid-mount placement near the crank lowers the center of gravity and centralizes mass to optimize vehicle handling, while 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 is required … just pedal and go.

Four Ride Modes:

  • Eco Mode for a gentle amount of assistance in flat-and-favorable conditions.
  • Tour Mode for the optimal blend of assistance and battery economy under mixed riding conditions.
  • Sport Mode for pronounced assistance away from corners or over rolling hills.
  • Boost Mode for confronting a steep hill, a strong headwind, or any other condition requiring a sustained boost.

Walk Assist: A push-button ‘‘walk-assist’’ function located on the handlebar controls provides a low level of forward motion to help easily maneuver the eBicycle at walking speeds, especially if there is ever a need to push it up a hill.

Belt Drive: Gates Carbon Drive belt is smooth, quiet and maintenance-free. It requires none of the frequent lubrication or adjustment of a chain-drive system. It never gets greasy or messy.

Auto-Shifting Transmission: 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. Fully-enclosed and maintenance-free, it’s available on select models.

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.

Serial 1 App Compatibility: A smartphone with the Serial 1 App, when paired by Bluetooth with the Serial 1 eBicycle, will provide access to key rider data. The Serial 1 App will launch in Spring 2021.

Hydraulic Disc Brakes: Front and rear hydraulic disc brakes utilize 203mm brake rotors designed to deliver confident braking performance in most riding conditions — essential for faster-moving eBicycles and all-weather commuting.

Internal Routing: 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.

The Rush City model is a premium, full-featured eBicycle designed for more convenient and fun commutes. The easiest, most intuitive way to get anywhere, without breaking a sweat.

Integrated Lighting: A bright LED headlamp mounted on the handlebar stem illuminates the path ahead and can make the rider more conspicuous after dark. Bright combination LED tail and brake lights integrated into the frame dropouts are designed to make the bike more visible from the rear. 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.

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.
