I've been told to lose some tonnage, and think getting a mountain bike would be a good way to go, BUTT, I sat on an expensive bike with a seat with a shock absorber-type spring under it, and the spring bottomed out! I'm 48 years old, and haven't been near a bike in 30 years.
Yikes! At 5'10", 220#, are there no comfortable mountain bikes out there for chubs? I'm not gonna climb any trees with the thing, I just want the option to ride some dirt roads if I want to. Slow and easy, no hard-core riding.
