  • Patent number: 6572129
    Abstract: A recumbent tricycle which includes a propulsion system which includes a combination of foot and arm power for propulsion. Pedals are operated with the rider's legs. Handles are also connected to the drive mechanism, with the handles pulled back and pushed forward to add to propulsive power. The handles are also connected through a tie rod arrangement to the front wheels such that the wheels may be turned so that the vehicle can be steered by moving the handles toward one side or the other. Preferably, two large front wheels similar to conventional bicycle wheels are provided in front, with a single smaller diameter but wider driven rear wheel. The rear wheel is mounted on a sub-frame pivotally secured to the vehicle frame and supported on a shock absorber. Brake and gear change mechanism controllers are mounted on the handles.
