If you had a ride/bus/ride commute with roughly 20 miles of riding for the round trip what would you go with?
So far a custom singlespeed build around a Xootr Swift frameset seems like the best option. I've been commuting on a singlespeed for many years, and having a simple drivetrain for something like this seems like the way to go. I'm also 6'2" (175ish pounds) so the availability of larger sizes is appealing. I also like the frameset idea because I'm a picky bike nerd.
I'd be willing to sacrifice a little folding speed/convenience for something that feels more like a conventional bike.
