I used to be a fan of this service in Germany for a while. Features are the same (Track it online or grab one from the street, unlock it with your phone, leave it everywhere you want), it's operated by the 'Deutsche Bahn' railway comp.
It was cheap, easy and the bikes were of good quality, plus you can't beat the flexibility of grabbing one of those to meet a friend on the other side of the city.
Great to see that the concept spreads further and further.
) They define a general area in their TOS/contract. You're not supposed to leave it outside of the city limits, for example. You can leave, of course, but need to drive back into the city limits to drop it off.
