How can the limiting device work out if on a footway?
And it seems they need to be registered, so that's another hurdle.
My recent one, is a Veleco Gravis. This is legally sold, set to max of 8mph, and has to be registered, and taxed - both free. In the EU, the same model is legally able to do 4, 8, and 16mph. Like many, most all, I have enabled the maximum 16mph/made it available, for my own personal safety, in certain situations. One of those situations, is a narrow single track bridge crossing a railway. A tight right to get on the bridge, a tight left to get off it, and zero visibility on the approach, unless you tuck yourself tight over to the left, on either approach. Numerous dumb driver, don't appreciate the lack of vision, need for care, and approach as if they intend to carry on over the bridge regardless. There are numerous occasions where two cars meet head-on, lost tempers, and one has to reverse.
My approach either on scooter, or in car, is always to tuck as far as I can to the left, then if it's free, begin to cross. On the scooter, I then move well over to the right, to both prevent anyone attempting to overtake me on the bridge (as some have been known to try), and to make oncoming vehicles see my approach sooner, make it absolutely clear I will not be giving way to them.
The speed switch, is marked 1, 2, 3, and it uses a brushless 3phase 1000w motor. The motor speed, when it is on the level, or going up an incline reaches the maximum speed setting, then will go no faster. On a downhill slope, it freewheels, and can go faster, and the motor will simply not attempt to drive.
So far as the speed setting goes, I engage common sense. On the pavement with people about, I run it on 1, or less. On a totally empty pavement, I might switch to 2. However, some pavements are so badly made, with lots of steep sideways drives, they are enough to throw you off, in which case I go on the road - as I have every right to do with a fully taxed, and registered vehicle.
