In this video you see me making a huge DIY electric scooter with a car wheel as rear tire.

For the previous project a bought a set of 4 Porsche rims and I only used 2, so I had still 2 spares. I found a motorcycle tire that fitted the 8.5 x 17" rim and so the project started.

I used 2 hoverboard motors which I bolted together. I recycled them from another project I did not use anymore. Check this video if you want to see how I built these motors:    • How to build a DIY electric powered f...  

It drives very well. Not that fast but nice and comfortable, and the hydraulic disc brake is more than powerful enough. I am planning to build a big battery for it because those chinese hoverboard batteries are a bit weak.

Technical details:
- 2x hoverboard motor 350w 36v
- 2x brushless controllers 350w 48v (BLDC) from Aliexpress
- 4x hoverboard battery 36v 4.4Ah
- topspeed 27 km/h
- tire size front 145/70 - 6 rear 210/50/17 on 8.5 x 17 rim
- frame built out of 30x60 square tube 2mm wall thickness
