I am not sure if this has been done before, I haven't seen it near me.
I have always wanted to own a bike here, but the size of my apartment doesn't allow me enough storage space to keep one, so whenever I want to ride I always have to rent some POS from a shop close to where I am riding. What would be amazing is if I could purchase a bike from a shop and they provide storage for a small monthly fee. Whenever I want to ride I could request my bike from either their website or smartphone app, say the day before and have it delivered to the shop closest to me (or even better my home). I would pick the bike up and ride it and then deliver back to the shop to be placed back in storage.
Forget about a shop in Central, with something like I described, you could be online only or have a location somewhere where the rent isn't absurd. Good luck.
