California Superbike School demonstrates its 'No B.S.' bike, which has fixed handlebars so riders can only steer with body lean. It illustrates how little control that gives compared with countersteering.

Veritasium explains why bicycles are stable, arguing that gyroscopic effects are not the answer. The video shows countersteering and an experiment where riders blocked from steering the opposite way cannot turn.

A two-minute minutephysics video explaining why turning a bicycle requires first steering briefly the other way. It covers counter-steering and balance with slow-motion footage and 3D animation.
