Muscle-powered skateboard is operated via backpack drive of flywheel shafted to board wheels via and operated by pullropes led from drive over shoulders for arm pull.

摘要

The skateboard comprises drive part with flywheel (SR) and freewheel (FL) powered by one or both arms in the shape of a flat backpack. The second part consists of the board itself with shaft-powered wheel or wheels (AP). The drive pack is joined to the skateboard by plug-in arrestable flexible shaft (KW), with board-fitted brake (B) and couplings (KH). A fifth wheel between the wheel pair and larger than these acts as drive wheel for firm ground contact despite undulating terrain. Pullropes (ZS) over each shoulder are for drive power application.
