Thousands of these Velieb bikes in Paris. Brilliant. Loads of banks of parking for them. Just pick up a bike - cycle where you need to - leave bike at destination in nearest Velib parking - and they are all over the place. Paid for by the length of time you use the bike. Built in dynamo lights, basket for a bit of load carrying, chain guards so you don't get dirty clothes... they were in use all over the place.
