Generation Zero has bicycles as the main “silent” vehicle to get around, so you don’t alert the machines.

Parcel Corps (I played the demo a while back, I don’t know if it’s fully released) is about bicycle couriers, in a cool vibrant city. It kinda reminds me of JSRF in a couple ways, as you ride around on your bike and do all sorts of cool tricks, and there’s a funky soundtrack (from what I remember).
