Single-speed... I just don't get it

The only time I use a rear brake is when hurtling downhill and not wanting to send myself over the bars. Then I use a little rear before I add in the front brake to control it. Otherwise, rear brake is never touched.

so when i do this fixed....
hit the crest of the top you're already going quite slow... so you run you legs loooooooose.

Then put a bit of back pressure on when you start picking up speed, and give a little tweaks on the front brake. Then spin and apply back pressure as an when you wanna reduce abit of speed. This is the way i do it.

Brakeless would scare the living shit outta me.
