Designed as an alternative to training wheels, the Gyrowheel senses imbalanced riding and recenters the bicycle once it begins to wobble. This effect is accomplished by an interior disk that spins independently of the wheel to stabilize the bike even at very low speeds. It installs quickly with a wrench and has a simple on/off button, three stability settings, rechargeable batteries, and light and sound indicators. The 12" Gyrowheel is available in black and white.

— John MacDougall, owner of Golden Apple Learning Store in Pleasanton, Calif., was impressed with this product at Toy Fair 2010. It's "a step up from a balance bike with a gyro that keeps balance without training wheels. Tech + Bike = Perfect," he said.
