I will put in my 2¢ I ride this bike, It is upright and very comfortable
http://www.citybikes.coop/citybike.html I don't know where you live but there custom 2008 models are a nice price and they come with everything a clyde needs for under $400.00 I/E double wall 36 spoke rims metal pedals. It may be worth the shipping (not sure how much that cost ) but it is a good bike for the money. I started ridding at over 500lbs and the only problem i had was I knocked my front wheel out of true comming off a small curb (my bad) I currently have over 250 miles on it in 3 months so I have been ridding it. Good luck
