Yeah, they do offer more sizing options on their more expensive offerings, but I'm assuming because this is there most affordable option, they probably help keep costs down by limiting they amount of sizes they offer.

I Typically don't go for the cheapest option, but this is my first Single Speed, and I'm not sure it's something I'm going to ride a ton but I wanted to give it a try, combine that with the fact these cheap State Bike Co. steel bikes are currently getting pretty good reviews. I've got a friend that has one and she LOVES it, unfortunately she's on the smallest size, otherwise I would have taken hers for a spin to gauge size.
