Just throwing this out there. I'm not sure of the brand but a gentleman in my town who was 350-400 pounds bought a electric bike. Just getting his body moving everyday with the help of the electric bike he dropped over 100lbs and some say 150lbs over the course of the riding season. The bike looked a little bit like a motorcycle to be honest and it had some beefy fat tires on it. If you can afford it I think it's something to consider.
