摘要

Improvements in the construction of devices to drive the biped or rider of the motorcycles, characterized in that the biped is articulated to a bar, which moves longitudinally with respect to the vehicle, occupying two extreme positions, one previously requested by a spring, in which two-wheeled wheels support the ground and a rear one where these wheels are collected and to which the bar is dragged by the rear wheel of the vehicle by means of a clutch, which is activated, after releasing the hitch that fixes the wheels in their position lower by the same device.
