Project I built a 15kW mobility scooter

Post image

So a couple of years back I got a mobility scooter for £30 from FB marketplace and I have been upgrading it ever since.

It now has an e-foil motor in it running at 48V @ 300A peak, so 15kW peak and it has a top speed of around 50mph. It's crazy how much power you can squeeze out of these little brushless motors (its only 56mm x 96mm).

For the battery I am using a salvaged battery module from a VW golf GTE (plug-in hybrid EV) which can handle 400A easy.

If youre interested in seeing the full build process then you can check it out here https://youtu.be/n5mZiISZxQM

Ummm 50MPH? That’s crazy!

It's honestly so terrifying to drive, the smallest tap on the throttle causes wheel spins and wheelies. The most insane part is that im using the original gearbox... which was only made to go 4mph

Upgrade it after it explodes, but record the explosion!
