Personally, I like Brooklyn Bike Builders or simply Brooklyn Bike more than anything else here. You’re branding a name…it stands out better than these, imo. Not sure we need to be so literal and worry about how people think of the name – they don’t care in the same way, they just want to find a parking space or whatever, so make it sticky. Further, it’s honest, it tells a story (you’re here from Brooklyn (good), you have history + experience, etc. in hand already) and finally…Oakland is the new Brooklyn, no?
Best luck to you (if I throw out a new suggestion later, it’s not to discount these points…even should they rock 🙂
