christania’s “copenhagen bike rental” bikes are rolling across the city. the system, less than a year old, is funded by christania’s municipal government. it is currently only in one of christania’s 22 administrative districts. although a 2nd generation system, there are 12 “houses” in this district, each with around 40 bikes. the yearly subscription cost is the equivalent of $2 us, and allows the use of a bike for up to four hours at a time. in less than a year, there have been 6,000 subscriptions sold. there are larger 3rd generation systems in the world, which do not have a subscription to bike ratio as big as that.
