Contact programs that are already in place? Tulsa has two that I know of:
-
Rack-N-Roll run by Tulsa Transit (bus service, no light rail here).
-
Tulsa Townies partnership between Tulsa Riverparks and a local hospital.
You could also check out
citibike in NYC, but they have gotten a bunch of backlash by the locals on how they've gone about setting up their kiosks...
