OK, True confessions.
I'm female, 5'8" and weigh 230. I'm 62 yo and not as steady on my feet (and maybe on a bike) as I used to be thanks to back surgery, pain, weight gain, and ? I'm thinking of bike riding to recondition myself and lose weight. I want to sit upright. I want a comfy seat. I think I want a few gears to help me not have to work so hard at first. Any input about bicycle vs tricycle vs bicycle with training wheels? I will only be riding for fitness and pleasure. I'd appreciate any input or suggestions.
