I recently got into cycling as a fun way to lose weight. I live in Northern Illinois and the winters are pretty hard. I want to be able to continue exercising with my bike through the winter. I am using an old mountain bike of mine that has a rear hub that is bolt on and not the skewer type. I am trying to determine if bike trainers will work with the bolt on type of hub. They all see to be made for the skewer type. I want to upgrade my bike at some point but right now it is not financially prudent. I have been looking at the Bell Motivator because of my budget right now but would be willing to look at others if they work with a bolt on hub.
