Hey - what are the rentable bikes called? I thought this system was really cool - I think you can call in and they will unlock them for you... We were very envious of people "Doo-da-doooing" thru Englisher (SP?) Park on them. Spent a few very good (read guts full of beer/stomachs full of sausage) days staying right in Viktuelen (SP?) Markt...
