The difference is surely that Evans would never sell brakless, so will be requiring the letter even for totally road legal fixeds. Probably mostly with two hand brakes.
I remember seeing a Bianchi Pista in Evans with Brakless™ and a sticker on the top tube. That was a while ago though, do they just fit everything with 2 brakes now?
A friend who is getting a bmx from Evans for bmx track use only is having ball ache getting it with one brake, said she needs to unbuild it a bit now it's arrived.
