I am a 48 year old male.6' 1" 290 pounds i am a powerlfter i have had several hand operations and i now have a rotator cuff tear and another operation coming my way. I use to be a pretty avid road rider 20 years ago. With my medical issues i can not deal with the seating position on a road bike. I am looking at the 3.0 trek navigator but the bike store guy is pushing me towards a mountain bike cause of my weight. Here is my riding requireiments . Some rails to trails riding paved and unpaved a rack with some kind of bag for maybe a fishing pole and meds i have diabetis so i need those things with. Here is where the issues start i want to be able to do 15 or 20 miles on the road at a fair pace . Basially i want a good bike that will do everything pretty good my budget is a $1000 . Any advice you can offer would be greatly appreaciaed i plan on using the bike a good amount ao really need your guys and gals in making a purchase that fits my needs so i get out the with fellow bike enthusists be comfortable and enjoy. Thank you , will
