The rear-drive track kit comes in 20- to 26-in. wheel sizes, takes about as long to install as changing a tire, and adds grip on sand and snow. The front ski (top right) is optional, but fun.
Ktrak's traction-boosting Rear-Drive Kit ($400), which consists of a composite wheel with a polyurethane track, is the first step in turning your mountain bike into a muscle-powered snowmobile. To complete the transformation, the Ski Kit ($130) swaps the front wheel with a single, steerable ski. The kits will be available in February and work with nearly any mountain bike. ktrakcycle.com

Culled from a half-century of Popular Mechanics issues (make that the first half of last century), The Boy Mechanic represents an age when imagination could conquer far more than the checkbook — when solving a problem was more satisfying than paying to have it go away.
