Promising review: "This is a nice affordable single speed bike! I bought this bike mainly for short commutes and leisurely rides. I have had many steel framed single speeds and fixed gear bikes over the years, and out of the box this is my favorite so far. On every other reasonably priced/mid range single speed I've had, I ended up having to replace the stock tubes and tires among other things, to make it actually ride-able. This was not the case here. Also, the 4130 line is MUCH lighter than comparably priced single speeds I've had from various manufacturers." Read more
