From the creators of the Mini comes the new Maxi power add-on. Weighing in at a beefier 11.3 kg the Maxi comes with a much more off-road capable 450W motor with a 25 or 35KM range depending on battery choice. This unit is flight-safe safe, comes with a reverse gear, lights and a horn. Definitely worth a look if you are looking into adding a bit of speed to your chair.
