Abstract: A pedal driven apparatus for a hybrid bicycle can be manually propelled, but also includes a motor unit for forward propulsion of the bicycle. The apparatus comprises manually operable pedals fixed for rotation with a pedal spindle for receiving a manually provided driving force, and a motor having a shaft for receiving a motor provided driving force. A first torque transmission path transfers the manually provided driving force to a sprocket of the pedal driven apparatus, and a second torque transmission path transfers the motor provided driving force to the sprocket of the pedal driven apparatus. A first one way drive means is provided in the first torque transmission path and second one way drive means is provided in the second torque transmission path. The manual driving force and motor driving force may be used separately or combined.
