Due to the increasing gas prices and my expanding waistline I have decided to get some exercise as well as save a few bucks on gas. So my question is what bike would best suite my needs. First off I am 6’3” and about 315lbs. I will be riding eight miles one-way to work and then back home after work. On all paved roads but they can be rough at times during pothole season. I live in Michigan and we get pot holes up here you could lose small children in. I went to my LBS yesterday and looked at a few but was just unsure if they would hold up under my weight any advice would be great. I really liked the Specialized Sequoia. My budget is about $700.00.
