I need some tips on how to get the bike around harder and faster when doing a 180
bike follows hips, hips follow shoulders, shoulders follow head. Hypersnazz told me that and it works realy well.
Use your legs to kind of push against your frame/cranks. If you spin to your left your left leg should be pushing your frame(if you spin to your right, then you push with your right leg..). Some people said that this realy works for them, and others it doesn't. So just try it out and see how it feels.
