Kettwiesel ONE Handbike

The Hase Kettwiesel ONE Handbike is an adaptive, e-powered recumbent trike designed to bring seamless mobility, comfort, and independence to everyday riding. Engineered with a raised seat height and an upward-folding upper steering unit, it allows for smooth, wobble-free transfers directly from a wheelchair. The rider’s posture and legs are fully supported by individually adjustable, protective leg rests, while an adjustable telescoping aluminum frame accommodates arm lengths starting from 40 cm (15¾ inches), making it ideal for both casual cruising and sportier rides.

At the heart of its performance is an intuitive hand-crank drive system coupled with a high-torque Bosch Performance Line CX electric motor delivering 100 Nm of torque. All essential braking and control elements are integrated directly into the hand cranks for easy, immediate reach. The system features an Enviolo Automatiq stepless hub, which handles gear shifting automatically based on rider cadence, drastically reducing the physical effort needed on steep climbs or long stretches. Combined with coupled hydraulic rear brakes, integrated LED lighting powered by the main 545 Wh battery, and customizable options, the Kettwiesel ONE Handbike offers a refined, barrier-free hand-cycling experience.
