I had issue with Carpal Tunnel and that caused a lot of numbness when I rode my bikes. I ended up having surgery to relieve the right hands issue as it was worse that the left. For the most part the only time I had issues was when I was using power equipment when mowing he grass or riding my bike, they seemed to aggravate the nerve more than anything else. It did not matter what kind of bike I was riding either. I also got rid of my gas powered equipment and replaced them with battery powered equipment.
