Winter is No Excuse to Not Ride Your Bike

The KTrak Snowcycle Conversion Kit takes your mountain bike and turns it into a tracked, human-powered snow (or sand) machine, complete with a front ski. Other snow bikes are great at going downhill, like the Hanson Ski-MX Kit or the Winter X Bike Kit, but the KTrak goes up, down and all around.

Bounce Your Load and Get Charged Up

Be. The. Battery.
A brilliantly simple concept will allow anyone who needs (a small amount of) power to generate their own just by walking around while wearing this special backpack. By mounting the pack's load on springs connected to a rack and pinion device that is, in turn, connected to a small generator, the wearer's natural walking motion can generate up to 7.4 watts of power. Plenty enough to keep your Nofriendo DS charged. Or your sniper rifle's night scope.

The bonus? By having the pack's load on springs, the backpack is more comfortable and ergonomic than a traditional backpack too.
