Thanks for the replies folks, I had a good chuckle at them. Andy in sig I thought that was very funny. (I've still to turn my attentions to Germany - this cycling is opening up a whole new world).
Anyway I've decided I'll just shout in my Scottish hard man accent "Git on yer bike !!".
Back to the wheels turning, as boys in Glasgow we used to shout at passing cyclists "Yur back wheels're gaun roon in sqer circles".
