Gyrobike’s Gyrowheel aims to replace traditional training wheels found on kid’s bicycles. At $100, this 12-inch contraption “replaces a standard front tire and has an adjustable-speed spinning disc inside, powered by a rechargeable battery.” Video after the break.

The idea is that you get the kid started on a high stability setting, and step them down until they’re not using the gyro at all.
