An all-access ride to wherever you want to go. The RUSH/CTY STEP-THRU is a premium eBicycle loaded with features and exceptional style. The step-thru frame makes it easy to get in the saddle without swinging a leg high over the seat, and to stand flat-footed over the bike at a stop – an essential urban-commute feature for some riders.

  • Motor: The lightweight, mid-mounted Brose S 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.
  • Belt: The Gate 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.
  • Hub: 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.
  • Battery: The RUSH/CTY STEP-THRU is equipped with an integrated, 529Wh lithium-ion battery that can be quickly removed from the frame without tools. The battery locks into the the frame for enhanced security.
  • Range: The integrated, removable, 529Wh lithium-ion battery delivers a real-world range of 30-90 miles, depending on ride-mode selection, terrain, and how much pedal input the rider supplies.
  • Charging: 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% = 4.75hrs; 0-75% = 2.6hrs.
  • Braking: 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.
  • Wheels and Tires: Wheels consist of 27.5 x 35mm alloy rims laced with stainless-steel spokes and fit with high-volume, 2.4-inch Schwalbe Super Moto-X tires. The result is a perfect combination of low rolling resistance, ample shock absorption, and responsive, predictable handling
  • Fenders and Racks: 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.
  • Lighting: LED headlamp on the handlebar stem illuminates the path ahead. Bright combination LED tail and brake lights integrated into the frame make the bike more visible from the rear.
  • Ride Modes: Eco Mode for a gentle amount of assistance in flat-and-favorable conditions. Tour Mode for the optimal blend of assistance. Sport Mode for pronounced assistance for hills, Boost Mode for steep hills, strong winds or other conditions requiring a boost
  • Glove Box: A compartment in the RUSH/CTY STEP-THRU downtube provides a convenient place to stow a lock or other small items you might wish to take along for the ride. The glove box has been specially designed to fit the ABUS BORDO family of premium, secure locks.
  • 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.  Size is based on inseam and height.
  • Integration: 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.
  • Styling: Contemporary design touches like the sleek, integrated battery, the elevated chainstays, and the mass-centralized motor position all mark the beauty, craftsmanship and emotional connection inspired by Harley-Davidson.
  • What Size Bike is for Me?: SMALL = 4'11" - 5'7", MEDIUM = 5'3" - 5'10", LARGE = 5'7" - 6'1", XLARGE = 5'9 - 6'5"+. Note the overlap on all sizes. Riders will easily fit on more than one size for all models.
  • Sizing Recommendations: We recommend the smaller size if you want the ebike to feel more responsive and playful & larger size if you want the ebike to feel more steady and stable for straight line cruising or carrying cargo.
