Electric Sportster
Here is a demo of the acceleration, speed, and hill-climbing capabilities of the Electric Sportster. I was not using full throttle in any of these tests however because I'm still inexperienced with the amount of power the motors are capable of, so all the demos were done within my comfort levels rather than at the maximum capabilities of the board.
Here is a first person point of view of using the Electric Sportster. In the first run, I'm using just the throttle to accelerate and control my speed, finally braking at the end of the path. After turning the board around, I don't press anything on the remote and kick start. Then, I activate "Cruise Control with Braking" which applies propulsion and braking in order to maintain speed. I then use the throttle to gain speed, which deactivates cruise control mode. This drops power from whatever it was using to maintain my speed as the throttle moves from 0% up to the power defined by the throttle. Then I activate "Cruise Control with Braking Disabled" which allows the board to increase speed either by kicking like in the video or when going downhill. However, when kicking to increase speed, it is better to release cruise control and reactivate after kicking to the speed you want.
