That dude has balls. I ride my tall bike breakless, but not on hills like that if I can avoid it. Plus on the tall bike it's easy cause the cranks are right above the rear wheel, but he really has to stretch to get his foot up there, nutty!

When I was a kid it was cool to go brakeless on BMX bikes with freewheels and that's how we stopped all the time. I tried using the front wheel a few times and the results were never good. Maybe I'll have to try it again...
