Here some that we saw in Ammens(wrong spelling

) France, with me and my dad pictured!(My dad doing a touristy pose, im trying to sneek in the picture)
These were held in place by a huge magnet, and when you wanted to hire them, you put money in i think(either money in the box by the stand or you got a card/key to put in the machine, i cant remember now) and you could use the bike. When your done with it, you can put it back anywhere, so you could basicly ride from one place, over to another and leave the bike there.
Great idea.
Bikes look rather heavy though!
