A coworker recently had back surgery and is looking for an upright-type bike to ride. He wants a more upright bike to avoid bending over as it was lower back surgery. Anyone have a used comfort bike or hard tail laying around that would fit someone 6' 4" that you're willing to sell? He only intends to ride the bike path so he can be out moving about and getting some exercise while his back continues to heal. It doesn't need to be anything stout or grand. The key is to not put him in a bent-over position.
