I'm very interested in buying a Brompton, but afraid that the 16 inch wheels and sitting my 6-foot 190-pound frame on a long-necked seat post for long rides will turn into torture. However, I get the idea from lurking in this forum for awhile that most riders are far more comfortable on their folders than I'm imagining. What's your experience with long rides, especially on 16 inch wheels and especially on a Brompton? I'm also interested in non-Brompton experiences. Are any tall, big guys finding them to be comfortable for long rides?

I've been reading a lot about the performance of the various folders, but haven't seen much written about comfort on long rides. I'm riding about 20-30 miles per day, with longer rides on weekends, and it's mostly road riding, although I do have to go off-road occasionally.

The reason I'm interested in the Brompton is the ability to fold it into an airlines-approved suitcase without taking it apart. I do a lot of air travel, and would like to just grab it and take it with me. My clothes and laptop are usually in my carry-on bags, so the Brompton could go for free in a checked bag (I get free checked luggage on Southwest - 62 inches, 50 pounds).

Thanks!
