This unique Wheel system is designed specifically for snow bikes (fits Mountain Horse systems), it will make moving your snow bike completely hassle free. The front wheel securely attaches to the ski and is tightened down with a ratchet strap. The back wheel simply sits down into the lugs of the track and self aligns. The system can be installed in a few seconds allowing you to easily push your bike around on any surface without it tipping over. You can also use them to push your snow bike up a ramp into a truck bed and/or to ride your snow bike in and out of the trailer or down a gravel roads that has no snow on it.
