Some of these single gear bikes look great, easy to maintain, but I would also like to keep up with my road bike friends who insist on wearing spandex. I have nothing agasint anyone wearing anything they like, but I am not going to wear spandex plus I want a bike I can commute with daily.

I am 6'4" and need something with a big frame. I want to purchase the parts seperately and have a bike shop put them together.
