I think that the UK law requires two independently operated brakes and so it is illegal to run brakeless (the back wheel is only one brake), but legal to run a single front brake. Lima got busted by the 5-0 during one of the alleycats last year and had to walk back to the finish line while they followed him to make sure he didn't dide his bike. He ended up mooning them which was pretty funny.
