The Copenhagenize Index gives cities marks for their efforts - or lack thereof - towards reestablishing the bicycle as a feasible, accepted and practical form of transport. Cities were given between 0 and 4 points in 13 different categories, with a potential for 12 bonus points awarded for particularly impressive efforts or results. In short, a maximum of 64 points could be awarded.

The final list of the top 20 bicycle friendly cities offers up some surprises. The top two cities - Amsterdam and Copenhagen - will probably surprise noone but it is interesting to see cities like Montreal, Guadalajara, Rio de Janeiro, New York City and Dublin ranking so well.
