Made from high-strength, lightweight aluminum, the Black Widow folding bike ramp has a 750-pound weight capacity and is the ultimate combination of strength and convenience. Arched for maximum clearance, this ramp features hinge system that allows the ramp to be folded in half for compact storage and transportability. Heavy-duty serrated cross bars provide excellent traction in any weather condition, and the tapered bottom edge making the loading process as safe and smooth as possible. This ramp is held in place by a set of rubber-coated fingers that grip the tailgate without scratching and an included adjustable safety strap. We recommend always working with at least two people when using single-runner ramps for loading. These aluminum motocross ramps are not intended for riding your bike up because they are not wide enough to put your feet down when loading and unloading.
