I have a friend who weights about 300 pounds who would like to get a bike so she can ride around the neighborhood with her kids. They are just getting to the point of riding without training wheels.
I have a Huffy 10 speed cruiser with 26" wheels and wider tires. I could set that up for her for about $30, but don't know that it would be robust enough. What older ( 70's/80's) bike or type of bikes would you recommend? I am thinking a name brand mountain bike and that the wheels (rear) is going to be the weak link.
