Two words: RALEIGH CHOPPER!
Raleigh may not be the coolest brand, but the Chopper still cuts the mustard in the cool stakes for me. Got a genuine 1972 Mk II undergoing restoration in the shed. Never owned one when I was a kid, so when I got the opportunity to buy one at the local tip for £5, I pretty much took the guys hand off for it. That was 10 years ago, and I reckon at least once every week since then I just gaze at it in wonder at just how damn cool it really is.
Apart from that, Pashley are a cool brand........especially the Pashley Guv'nor.
