i'm definately thinking of getting one of these. thing is i think the brake lever ones are a bit silly..... it's a good idea, but i think it's just going to restrict itself when your going along accidently because the codes going to be something you use at somepoint in natural riding. i personally think the switch is the best idea.....there are so many places you can hide it where they wont find it, also are they really going to argue? ....how are they going to know there are devices that can restrict them? ...and also.....it will be a restricted bike after all so what can they say? and they are very cheap considering the hassle it would save you! ...i think i saw them for about 20 pounds which is definately fine by me
