Purpose of the Design: The tilting rear wheels help balance the bike at slow speeds.

As the child builds up forward momentum, the wheels shift inward due to decreased weight on the rear wheels, thus causing the balance to gradually shift from the bicycle to the child.

Shift provides more balance at lower speeds when stability is most critical (starting and stopping), by providing a larger stance.

The Shift bicycle features a swinging rear hub, which allows the rear wheels to pitch in and out.

The hub allows for the rear wheels to provide a larger or smaller stance depending on the amount to weight on the rear wheels. An internal belt keeps the drive train away from the children for safety.
