Oy! Give us a lift, then!
This is Oybike, a London based bike rental scheme (modelled on those on the Continent) that lets you use a bike for as long as you need, the first half hour is free. You take it from one place and you can drop it in another. It's a fascinating idea, designed to work in conjunction with public transport - the map of London locations is here. I suppose that the scheme becomes more practical the more places there are, but how they don't get nicked from here - Gallions Reach - I'll never know.
