Our top speed measurement for the Pro is 37 mph and 39.3 for the base model.
Our newest unit is more than a year old, so it’s possible that they have updated since then.
Top speed is mainly a function of how much current the controllers will push (times voltage = power). Sometimes we’ll run into a scooter with a firmware limit on top speed, but that’s pretty rare in the US market for light heavyweight scooters (like the Mantis).
These are the curves from our top speed runs (north and southbound runs on flat ground averaged together to cancel our headwind/tailwind)
Vertical units are mph, horizontal units are seconds.
