Abstract
A transmission system is provided for a tandem bicycle having a frame on which are mounted a front, steerable, ground engaging wheel, and a rear, driven, ground engaging wheel. The bicycle also includes front and rear pedal systems, each of which includes a shaft rotatably mounted in a hub carried by the frame, each shaft having axial ends to which pedal cranks are connected for rotating the shaft in response to pedal rotation of the cranks. The transmission system includes first apparatus for coupling the shaft of the front pedal system to the rear wheel so that pedal rotation of the cranks connected to the last mentioned shaft imparts rotation to the driven wheel. The system further includes second apparatus for coupling the shaft of the rear pedal system to the rear wheel so that pedal rotation of the cranks connected to the last mentioned shaft imparts rotation to the driven wheel. The first and second apparatus are constructed and arranged so that pedal rotation of the cranks connected to one of the shaft imparts rotation to the driven wheel without imparting rotation to the other of the shafts.
