I have posted about all kinds of cool chairs here on Rollinpix, and I have found another great one with the ever present, almost obligatory Youtube video to show you just how wicked this rig is. The chair itself uses a combination of mountain bike parts, knobbie tires with optional snow chains and a shiftable gear change system with ratchet levers that are removable when the goings not so difficult. One of the Rengades coolest accessories are ski's that can be used instead of front casters
