Item #FreeRad-Conversion

$600.00 $499.00

Let us take your existing bike and Xtracyclerize it with a “Free Radical” extension kit (for 26″ wheels). These modifications turn your bike into a cargo hauling beast which can carry up to 400 pounds of stuff. Go grocery shopping and buy 8 bags of food or give a friend a ride home on the back. The Xtracycle performs these chores with ease and still handles like a normal bicycle.

The Free Radical attachment fits most 26″ mountain bikes with 7, 8, 9 or 10 speed (in the rear) with linear pull (V) brakes or disc brakes.

All the Xtracycle attachments function with this kit.
