Abstract
A foot-pedal operated cart includes a dual derailleur transmission system operated by a pair of multi-function control handles. The control handles each include a pair of hand-operated actuators for controlling a ratchet and pawl mechanism for respectively indexing the derailleurs over a pair of speed change sprocket clusters. The control handles are also connected to a steering system and braking system to allow a driver to control each system via the control handles.
