Which end has the handlebars?

Greg, not being in possession of a suitable bike, has borrowed Rob's second one.

I'll say that again. Rob's second bike. Rob has one road racing bike. And another one. He's like that.

By all accounts, according to Greg, this is a highly-strung thoroughbred of a machine. It bears some similarities with bikes Greg has known. In that there's a wheel at each end. But the brakes are somewhere completely random, and you have to wear special shoes that clip straight onto the pedal arrangement. A Raleigh Chopper it is not.

Greg is scared of his bike.
