Well I thought I had it figured out and was getting myself a MTB and my husband a comfort, but after remembering and riding a MTB and feeling the pain in my lower back I dont know about the riding position. Also I have been reading and not many people have good things to say about comfort bikes other than the comfy seats. Should I be looking for toward a hybrid? Just for reference again we will be riding the creeper trail which is a rail trail, greenways, parks, some light mountain trails, and maybe some road riding. I know we are both wanting something comfortable for our back issues but something we will be happy with for awhile. Speed and things of that nature are not a huge issue. Help!
