The first commercially available powered monowheel on the market, the Wheelsurf is powered by a Honda GX31 4-stroke motor and can reach speeds of up to 40kph. Made in the Netherlands, the $6,396 “bike,” for lack of a better word, is not street legal and can only be used on private roads.>The Wheelsurf consists of an inner and outer
frame. The inner frame, which contains the engine, drive train
and petrol tank, is where the rider sits and
has three small wheels that make contact with the outer
frame. The outer frame is the rotating wheel with a solid rubber tire.
The rider can steer by shifting his weight once up to speed. Braking is
limited to the counterbalance you provide by leaning backward. Brake too hard and you’ll start spinning. Wheelsurf PR considers
this “exciting.” We like to think of it as a dreamy nightmare.
