While I love my Aventon Level e-bike I would like to replace the thumb throttle with one that is more sensitive to low speed control. The factory throttle has no response over about a third of its travel and it is impossible to go under about 12 mph using it. Does anybody know who makes the controller used in the Aventon? If I could identify the controller (which I assume is buried somewhere in the downtube) I might be able to find a compatible throttle control that has better slow-speed control. Thanks.
