Bi-directional pedaling system

摘要

A forward drive apparatus for a bicycle is provided to work the bicycle in a forward rotation even during the back-pedaling of the bicycle. The forward drive apparatus includes a forward drive unit fixed to a pedal shaft, and which transfers the forward rotating force of pedal arms to a drive sprocket wheel; and a reverse drive unit for rotating the driving sprocket wheel in a forward direction by a rotation direction converting unit fixed to the pedal shaft and which transfers the reverse rotating force of pedal arms into the forward rotating force. The forward drive apparatus is advantageous in that the bicycle is driven forward through the simple reverse rotation of the pedal, without operating an additional clutch or lever, and the operation of bicycle is not interrupted at all even when the pedal has stopped during traveling. The bicycle is drawn in an easy manner in case where the user draws the bicycle rather than riding on it.
