Nifty - sharp idea, nicely worked out.
I used to have a friend that had to sit every once in a while during walks to catch his breath. This was back in the late seventies/early eighties. Being with him made me catch on to how few places there are to sit in some everyday locations. This friend was still interested in seeing museums and gardens, walking slowing around the city.
One question I have on the design is not really re the design, but usage - if people will pile on more and more bicycles. But then.. in some situations the city probably needs different kinds of bicycle housing.
