There is something special about riding a bicycle around the middle of a city. You weave through cars, people and anything else, crossing town quicker than than anybody else in rush hour. Even better it's you that's doing it, not the car or the oil it's burning, just you, burning off this morning's dodgy fry up. When was the last time you saw a fat person on a bike anyway? Even better, you get to see the world, I mean really see it. You can hear the birds and the buskers, smell the food and the garbage and actually catch a person's eye.
