Engineered to work with any stair system, the Bicycle Access Ramp features a modular design made of thick wall aluminum and rustproof, stainless steel mounting feet. The ramp is compatible with all types of bike tires, up to 5 inches wide, and features an anti-rollout ramp shape so cyclists can easily manoeuvre their bike with just one hand. The runnel is fitted grip tape to prevent tires from slipping once on the ramp.
