1 Year ago I was at 377 riding allot but not losing weight (I ate everything) I bent axles and popped spokes. My LBS worked with me and recommended a bike that would take my weight and size (7 foot tall) I have a Reilgh m80 that I have put 2000 miles on and have lost the weight, now at 275, and picked up a Trek 1000 that is treating me well. Get what you can but you will be hard on bikes. Your LBS is your best resource
