Wheelman is a new two-wheeled device that combines “the best of surfing, skating and skiing concept gears”.
It cruises along on spokeless wheels triggered by a 43cc 2-stroke engine. Drivers can easily fix in their feet into the wheels and drive it whilst standing upright. The oil holding capacity of the Wheelman is around one liter and delivers an hour and a half of smooth riding at a top speed of between 16-19mph, which is pumped via squeezing a pneumatic ball held in your hand. It steers with body and foot movements
