Homemade singlespeed bike

what is your bike for? its like a bit of everything?

No brake bridge? I know that strictly speaking its not a necessaity, but doesn't it help to minimise seatstay flex that is created from the power being applied to one side of the wheel? Honest question, as I am not an engineer.

@Willpalmer: I just use it for driving around the city....it's not specificly build for a special purpose, just felt like building this bike

@GA2G: I actually made a brake bridge for this frame, but when I tack welded it in place, I realized I liked the frame better without it. I know it helps minimizing flex but there is a pretty large weld area on seatstay-seattube section which seems to stiffen the rear end up enough. I didn't notice any flex so far (and I tried...)
