Here's the ultimate thrill for mountain bike enthusiasts: the Ktrak. Turn your regular bike into a snow bike, with this kit that loads your back wheel with traction and switches your front wheel for a ski.
Its rear-drive track system offers 25 times as much traction as the average mountain bike, and the front ski attachment opens biking up to all kinds of new possibilities.
Introduced last year, the kit is currently available for 26-inch wheels, but will soon be available for smaller models. Just make sure you get your brakes checked before setting off. RM
