So you want to keep riding even though there's snow on the ground, but you don’t have the cash to buy a true fat bike. That’s where the Ktrak Snowmobile Bike Kit comes in handy.
The kit turns your mountain bike into a human-powered snowmobile. Replace your front wheel with a ski and the rear one with the snow track—voilà, you now have a snowbike that’s ready for those deep powder days.
The kit is compatible with most standard mountain bikes, according to the company.
