The Gyrobike's[1] Gyrowheel contains a flywheel which spins independently within the front wheel of a bicycle, creating a force that steers the front wheel to help stabilize the bike.
Gyrobike uses the principle of gyroscopic precession to help stabilize the bike and the rider. Precession responds to a lean of the bike by turning the front wheel in the direction of the lean, which can help provide stability at low speeds, whether riding straight or turning.
The Gyrobike was invented by a group of four students at Dartmouth College for an engineering project. The children's model of the bike is a replacement for training wheels and is expected to be available for purchase in fall 2009. The adult-sized Gyrobike is intended to provide continuous stability for disabled, elderly or other riders. Product development is underway for the adult wheel.
