I don't know about the regulations in UK, but if it goes beyond the limit in the US (depending on the state, we all have different regulations), you'd need headlight, tail light, directional lights, brake light, probably other features to make it street legal. That said, my bike is entirely illegal in New York. They are entirely banned, though there is legislation in the works that would change that. I still ride just about every day. Then again, I know that Europe is older, more densely populated and infrastructure was based around pre-automobile transportation. When we get visitors they are always surprised by how far apart everything is, and how we have to drive everywhere. Bikes are far more common there.
