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: https://www.youtube.com/watch?v=fLjSSx9X8hs 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 Chapters: 0:00 - intro 0:08 - building the rear wheel hub 3:57 - building the frame 9:11 - making the removable frame part 10:33 - making the footrests 13:15 - mounting the motor 13:53 - welding everything out 14:38 - final assembly 15:30 - building the battery tray 18:02 - presentation of the finished product 19:11 - testdrive Leave your questions and remarks in the comments below, I will be happy to answer them.
