Serial 1 Rush/CTY Step

Your all-access ride to wherever you want to go, with premium features and a step-thru frame that makes it easy to get in the saddle without swinging a leg high over the seat.



Inspired by the entrepreneurial vision of Harley-Davidson’s founders—and the revolutionary impact of their first motorcycle, affectionately referred to as “Serial Number One”—Serial 1 offers innovative eBicycles that make every ride an adventure.

Born as a skunkworks inside Harley-Davidson’s Product Development Center, the eBicycle project began in 2018 with a small group of passionate motorcycle and bicycle enthusiasts working with a single focus, to design and develop the best and most capable eBicycles available today.

The Rush/CTY Step-through’s 529Wh lithium-ion battery is integrated into the lower frame for sleek style and convenient removal for off-the-bike charging. Depending on terrain, the RUSH/CTY STEP-THRU has a range of 30-90 mi/50-145 km and takes just 4.7 hours for a full charge.
