Thanks brant! 46.65″ WB sounds really good at the 20in model.
On page 1, you wrote that the ETT would be 630mm on the 20in though. Which is correct?
On a sidenote, I get the feeling when looking at, and reading about, On-One bikes that people always go with a small size. My notion is that 620mm ETT and ~430-440 reach is pretty spot on for most 6 footers. While a large bike isnt cool, a small definetly isnt either.
