Abstract: A rear wheel linkage system for connecting a rear wheel of a chain wheeled vehicle to a frame of the chained wheel vehicle, the chained wheeled vehicle having a front side, a rear side, and lateral sides, and comprises a pair of upper links, a pair of lower links, and a coupler link. The upper links are configured to be hingedly joined to first locations of the frame, at a rear of the frame above or near a top of the rear wheel. The lower links are configured to be hingedly joined to second locations of the frame, ahead of the rear wheel. The coupler link is configured to be hingedly joined to both sides of an axle of the rear wheel, the coupler link has an upper side, a lower side, and a front side and to be hingedly joined to upper links, the lower links, and the frame.
