Abstract: A collapsible bicycle storage device may include a bracket assembly including a mounting portion for mounting the bracket assembly to a wall or ceiling, and an arm support assembly for supporting one or more bicycle support arms in the bracket assembly. The arm support assembly supports an arm assembly having at least one bicycle support arm rotatably mounted in the bracket assembly for rotation between a stowage position and an operational position.

Abstract: A third axle is provided with auxiliary wheel mounts at opposite ends. Auxiliary cantilever leaf springs are fixed at their rear ends to the third axle and are pivotally connected at their forward ends to anchor plates which are mountable on the main rear axle, using the existing or similar U-shaped bolts normally used to attach the rear chassis frame support springs to the rear axle. Load transferring brackets secured to the chassis frame rest against the auxiliary springs intermediate their ends to transfer a predetermined portion of the load to the auxiliary wheels under all load conditions. The brackets are clamped to the chassis frame by bolts which bear against the top and bottom surfaces of portions of the frame to eliminate drilling, welding or otherwise modifying the frame.
