Anyway - Guy has just broken the national speed record for riding a bike. 112 miles per hour - that's right - 112mph on a push bike.
He did it by riding in the slipstream of a racing truck fitted with a windbreak - he had to cycle no more than 4 inches behind it - scary or what?!
The bike was specially made and features twin chainrings driving a massive gear - almost eight times that used by a typical Tour de France rider - he had to be towed to 60mph because the gears are too big to turn from a standing start.
There's a TV programme on Channel 4 on December 28 - can't wait to see how they did it!
