So, I've been loving my first e-bike for about a month now. Last week I moved to a new house further away from work, so my commute more than doubled to 9.5 miles one way. Now, by the time I get to work, the top of my hand is sore from holding the thumb throttle down all that time. I tried readjusting my position, holding it in place with a more passive grip, but nothing really works. Have any of you experienced this, and is there a throttle type that you prefer over a thumb throttle?
