The Sportrack Ridge 4 Towing Hitch Bike Rack is a great way to transport your bikes while also being able to tow up to 2,000lbs. The hitch-ball mount allows you to tow your bikes without having to worry about them getting damaged. The anti-sway soft rubber cradles prevent bike to bike contact and hold bikes secure. The tilts down feature allows for easy rear vehicle access. The locking kit available (SR0022) makes it so your bikes are always secure. This hitch bike rack fits 2 inch receivers only. Please note some frame styles may require a Thule Frame Adapter to securely attach to hanging bike racks.
