BikeTree is a brilliantly elegant, green solution to secure bike storage in urban cores. Simply swipe your smart card, insert your bike into the slot at the foot of the BikeTree and go 'ooh!' as it glides up the trunk to be securely stored in the transparent canopy, out of harm (and nasty bike thieves') way. Naturally, the lifting mechanism is solar powered.) At the moment BikeTree is only installed in Geneva, Switzerland. It would be great to see such an elegant, clean, green innovation used in London. How about it, Ken?
