ABSTRACT:
A tandem bicycle is disclosed which comprises a frame in part, like that of a tandem bicycle with the rear like that of an adult tricycle particularly adapted to allow two people to propel the vehicle while offering the riders stability so that both occupants experience the physical benefits of propelling the vehicle. Upon an elongated frame, like that of a tandem bicycle, there are two seats, each one mounted behind a pair of handle members, one behind the other. There are also two pairs of pedals in position to be engaged by each rider. In the present invention, the mechanisms associated with the second or rear seat are operable and influence the propulsion and stopping of the vehicle, except for the rear handle members which may not be moved and do not influence steering.
