gyroscopic effects gyroscopic effects do play a role in bike steering i think but it is a rather technical issue more suitable for a more technical exposition of than for the wikipedia article in order to get to the required lean the bike must roll the front wheel acts like a gyroscope wheel when there is roll the wheel's gyroscopic response is to yaw for definitions see pitch roll yaw i rather suspect that this contributes to the fact that it is possible to steer a bicycle accurately without hands on the handlebars i also suspect that the gyroscopic effects contribute to the experience of effortlessness of well executed countersteering talk
