The Fatboy Harlem V3

The Fatboy Harlem V3 is the next generation of Australia's most approachable fat-tyre e-bike. More efficient, more comfortable, and more capable than ever, the Harlem V3 is built around a step-through frame that makes it perfect for smaller riders, families, and anyone who wants a confident, comfortable ride every time. Every V3 has been redesigned from the ground up — new electronics, custom suspension, upgraded braking, and the intelligent FBX power architecture developed alongside Bafang — delivering a smoother, smarter, and more enjoyable ride than any previous Harlem.
