  • Patent number: 5417445
    Abstract: A pedal cycle is disclosed, which has a rear wheel suspension pivoted to the main frame and a front wheel suspension pivotally and slidably mounted to the main frame. Front and rear suspensions are provided and are interconnected, for example, by a rod to transmit forces between them. Any load on one wheel, tending to lift that wheel by movement of its suspension relative to the main frame, is transmitted to the other suspension thereby tending to lift that suspension relative to the main frame. Further, load placed on the front suspension by a rider pushing downward on a forward pedal causes a force to be transmitted to the rear suspension in opposition to a force applied to the rear suspension by a tension developed in the transmission chain owing to the force applied by the rider to the forward pedal. The interaction between transmission and suspension provides for a cycle with better responsiveness than in a conventional cycle.
