Not a bad conversion, but it’s got a few things that could be fixed/improved. First, fix the saddle angle for one. Anybody who argues that saddles don’t need to be flat is wrong. It will take pressure off your wrists and hands. It will also keep you from sliding forward. Second, add some foot retention. It keeps you from taking a pedal to the shin and helps transfer power to the drive train. If you don’t like foot retention (an argument I hear quite often), get used to it. It is a necessary part of a fixed gear bike. And lastly, add some tape or grips. The bare bar trend is a dead fad. I think this conversion has some serious potential with a few tweaks.

fixed gear is a whole different beast. foot retention is mandatory imo. single speed not so much. beautiful build so far.

ditto on pretty much everything blendo has said.
no need for foot retention on freewheel, but might be a smart choice to have a rear brake.

otherwise, imagining this bike with a level saddle and some tape, its a very nice classy build.
