DEMOUNTABLE DEVICE FOR TRANSFORMATION OF TREADLE LEVER ROCKING MOVEMENT INTO ROTARY MOVEMENT OF BICYCLE'S DRIVE SHAFT.

摘要

Demountable devices for transformation of treadle lever rocking movement into rotary movement of bicycle's drive shaft consist of two main units: redesigned driving unit for conventional bicycles and a reverse gear. Both units interact with each other through a flexible transmission. The devices can be mounted on most conventional bicycles. Bicycle's movement is provided by regular pressing of the cyclist's leg on the treadle lever. Length of the treadle lever can be adjustable.
