Easily load your trike onto any pickup truck or trailer by yourself with this high-quality, aircraft-grade aluminum Big Boy III ramp. Available in four lengths from 96" to 144" for transporting extended wheelbase trikes and motorcycles, this extra-wide 57" ramp provides ample room for you to plant your feet while you load and unload your ride.

A ribbed, cross-rung design affords superior traction for an additional level of safety when hauling trikes on your own. While the extra width is ideal for loading any type of trike or motorcycle, from sportbikes and cruisers to Harley Trikes and Can-Am Spyders, some custom trikes may require wood blocks to be placed at the end of the ramps to ensure safe clearance of the exhaust pipes.

The Big Boy III arched folding ramp system is one of the most versatile ramps on the market, and features a three-piece interlocking design for optimal performance and durability. Designed with a 12° offset, the heavy-duty hinge provides the proper arch to eliminate the risk of bottoming out.

Four quick-connecting support brackets hold the three sections together and eliminate ramp flex during loading and unloading. This innovative clamp system makes it simple to separate the ramp sections quickly and efficiently by pulling a spring clip on the support bracket. Thanks to their heavy-duty hinges, these individual ramp sections fold down to half their length, allowing you to store them neatly in your pickup truck or garage.

Keeping the ramp square with your truck or trailer while loading, the 3-3/4" ramp end features a solid flat plate/hook combo, however, we highly recommend adding the Alumi-LocAlumi-Loc Attaching System to your order for maximum stability and safety. Three heavy-duty adjustable cam buckles are included with this durable Big Boy trike ramp to secure it to your vehicle and prevent kicking out while loading or unloading.
