ABSTRACT:
A power transfer apparatus for imparting drive motion to followers. The power transfer apparatus mechanically and rotatably communicates with a driven wheel of a vehicle and transfers rotary power to the non-driven wheel of a vehicle. The present invention teaches a power distribution apparatus for mountain bicycles that mechanically and rotatably communicate with a pedal driven wheel and that transfers rotary power to the non-driven wheel to improve the forward propulsion of the mountain bicycle under rough terrain riding conditions. The power transfer apparatus includes a first caliper assembly having a driver idler and an auxiliary free wheeling idler for engaging a pedal driven wheel of a bicycle, a cable drive system coupled to the driver idler transfers drive motion from the driven wheel to a second caliper assembly having a receiver idler that engages the drive motion to the non-driven wheel. The power transfer apparatus is user controlled and is actuated by an actuator coupled to the first and second caliper for controlling engagement of the driver and receiver idlers.
