50cycles had a base in Cambridge for nearly two years and in many ways it is cycling Nirvana - lots of serious, separate cycle tracks, miles of riverside riding, plentiful parking and tens of thousands of of fellow cyclists. This sped-up footage of the junction just to the south of the main college thoroughfare illustrates how a town ruled by bikes works. Look out for how most large vehicles make room for cyclists, but a couple of drivers clearly couldn't care less!

Is there anywhere else in the UK where similar numbers of cyclists can be seen at certain times of day?
