Ok, i am a large man that is trying to take control of my life. i am on a medical weight loss plan and am looking to add biking to my exercise regiment. I am 6'5" and currently at a bit over 500 lbs, down from a top weight of 606lbs. i currently walk 2 miles everyday @4mph and have a goal of starting to ride when i hit 450lbs. what i am looking for are some good suggestions of bikes that would be sturdy enough to support a moderate riding style of approx 8 miles a day to start. i would also like it to be able for more aggressive riding later as i continue to lose weight. any thoughts would be appreciated.
also i may have a line on a reasonable priced kona hoss frame and if anyone wants to list some durable parts that would be great also.
