ABSTRACT:
A rear suspension system for a bicycle or a tricycle having a main frame which includes rear wheel chain stays. Two or more swing arms, one for each chain stay, are pivotally mounted to the chain stays, with the front of the swing arms extending into the interior of the chain stays. The rear wheel or wheels (in the case of a tricycle), are rigidly attached to the end of these swing arms. An elastic member is interposed between the front end of each swing arm and the interior of each chain stay. This elastic member is preferably urethane rubber or a similar material placed in compression by being positioned underneath the front of the swing arm. When the cycle encounters a bump or road irregularity, the rear of the swing arms move upward, causing the front of the swing arms to pivot downward, increasing the loading on the elastic member and at the same time absorbing the shock from the road irregularity before it is transferred to the bicycle frame and rider.
