Rock The Bike



Turn your bicycle into an S.U.B.

The FreeRadical is the coolest, lightest, most maneuverable, easiest-to-use way of adding serious cargo capacity to your bicycle.

We’ve been riding the Xtracycle for over 5 years, and we use it to drop off packages to the FEDEX depot in Berkeley when you place an order. It’s super quick to load, fast and nimble to ride, and it’s always there when you need a place to carry groceries, sports equipment, picnic supplies, musical equipment, and your friends.

The FreeRadical kit comes from Xtracycle, a Socially Responsible business in California. It helps you lead a more environmentally sustainable lifestyle, without sacrificing your own sense of fun and style.

Installation takes about 2-3 hours, but is a one-time deal. You have to be comfortable dealing with cables and cable housing. A good test is whether you’ve installed a rear derailleur or a pair of brakes before. If you haven’t, it’s better to take your Xtracycle-ready bike and the FreeRadical to a trusted mechanic.
