    Regarding hall effect sensor throttles...

    Mike, This is a stand up, electric scooter, so there's not much to break on it. Except of course, the throttle, which is (after inspection) quite fragile/vulnerable in a crash. I managed to wrestle the new throttle apart. It does, indeed, have TWO magnets in it. They're mounted about 90...

    Regarding hall effect sensor throttles...

    I have an old scooter that ran well with a hall effect sensor throttle, at least until my son crashed it into a hedge. The throttle wires broke, so I took it apart to repair it. Whle doing so, I broke the wires off of the sensor. So, I ordered a couple replacement sensors (UGN3503U shipped...
