For those days when we have a crew together and don't want to take two cars, the Thule Verse 2 Bike Add-On is there to save the day. Designed for use with the Thule Verse 2 Bike Hitch Rack, the Verse 2 Bike Add-On doubles our bike capacity from two to four so the whole crew can shuttle in one car. The add-on rack can accommodate two extra bikes up to 55 pounds each and tires as wide as five inches. The telescoping arms ratchet down on our front wheel, securing our bikes without frame contact, and aluminum wheel wells and rubber straps secure our rear wheel. This add-on rack is specifically designed for the Thule Verse 2 Bike Hitch Rack and only works with a two-inch receiver hitch.
