Our TRS SE hitch bike rack is a heavy bike compatible rack that will carry up to two 50 lb. bikes with up to 4.5" tires. It's ready to carry fat-tire bikes right out of the box as well as other heavier bikes like beach cruisers, mountain bikes, and downhill bikes. One of it's most popular features is the ability to tilt away from the trunk with the bikes loaded. This makes getting ready for your ride even more convenient as you don't have to worry about loading all your gear before the bikes.
