Lateral stabilising support for bicycle - has chain-actuated retractable lateral supports pushed down by back pedalling

摘要

The bicycle's pedal arrangement brings lateral supports against the ground when the pedals are rotated backwards. The lateral supports with small ground wheels are built into the system of the driving sprocket wheels by means of a fork-shaped support. The rider can remain seated on the bicycle and may immediately continue forward travelling. In this case the support is brought immediately and automatically upwards by a spring system.
