An electric-powered personal transport vehicle with a board to support a weight of a user and one or more wheels driven by one or more electric motors is discussed. The electric motors are powered by one or more batteries. A throttle has a thumb wheel speed controller on a handlebar. The thumb wheel speed controller has a horizontal manipulation between accelerate, neutral, and brake input positions such that pressing the thumbwheel speed controller in a vertical direction will not result in an unintentional acceleration or braking.
