Lynx-Wheels allow for ease of loading and unloading your Snow Bike. The solid rubber tires are durable, and grip well on slippery surfaces. Mounted on a billet aluminum axle, with aluminum washers and stainless-steel bolts for a light weight set up, you'll never have to worry about it rusting. With the included locking pin, you can switch between a rigid set up, which allows for tying down your bike, or an articulating set up when unlocked. Removal of the locking pin allows the bike to be steered just as it would be if riding. This makes moving it around on hard surfaces much easier and prolongs the life of your ski. The system takes less than 5 mins to install, with simple hand tools. Once the main bracket is on, switching between wheels and ski takes seconds.
