[QUOTE="Fred W, post: 1320808, member: 3828"] Actually, you turn a bike the same way at any speed, it is just more pronounced at higher speeds. You turn the bike by getting it leaned in the direction you want it to go. You do this by steering the front wheel in the opposite direction you want to go. Once the bike has some lean angle the front wheel wants to turn itself in the direction that it is leaned due to the steering angle trail force and gyroscopic force of the tilting wheel (try tilting a horizontally spinning gyroscope some time). That is why you have to keep pushing on the inside bar (or pulling on ionbeam's outside bar) to stay in the turn. Even at slow speeds, if the wheel didn't turn itself (or you didn't help it) back into the turn after the initial counter-steering, the bike would just fall on its side. You could demonstrate that by locking the wheel straight forward on a bicycle. You can get it to lean one way or the other by shifting the weight but it won't turn and you will fall on your side.
