geometry is odd, frame construction looks odd, the bike just looks confused.
But it wasn't purpose-built as a single-speed/fixie... it's just stripped down version of the other Trek Sohos, but with horizontal ends. Geometry is much more hybrid-commuter-ish than other off-the-shelf fixed/ss bikes.
And every time trek tries to do the built-in top tube protector, I think it just seems weird.
and "alloy flip-flop hubs, alloy rims" seems a bit iffy on a >$500 bike.
For $550, I think there are other bikes worth takin' a look at.
Just my $.02
