I'd like to surprise my wife by buying here a bike for here birthday.I'm looking to spend anywhere from $150-$200. I want to find a hardtail bike,no added suspension. I'm looking hard at some lady Schwinns,they look pretty good to me. My wife is on the heavy side,say way over 300 lbs. I know she won't be comfortable riding the streets,so I'm ging to have to get a car rack and drive to some parks where they have places that have low speed limits.I'd like for us to do this together,it's hard to loose weight by yourself and watching your spouse that isn't into it. Any suggestions? I'd go a little higher,but I'd be in enough trouble spending that much! Thanks.
