also if you get good at it you can start a skid and then swing the back out to the side. its a hockey stop. The trick with riding breakless is you have enough control that you never need to stop that fast. if you think things are getting dangerous slow down. admitedly i still haul ass across the city so I might be a little suicidal/********. its fun though, and a good way to wake me up fast in the morning. I'm pretty alert and focused about my surroundings and situation when I'm riding.
