# Part 1: DIY Electric Skatboard, Hub Motor & Trucks



In [episode 8](https://www.youtube.com/watch?v=Sjut8hVuLWM) of [my video blog](https://kaspars.net/go/vlog) I show how to modify standard skateboard trucks to fit [a 70mm electric hub motor from Maytech](http://www.maytech.cn/en/mto91hbm-ha/10270.html) (available for $99). This is a follow-up to [my review of the Maytech 90mm hub motors](https://kaspars.net/blog/electronics/maytech-90mm-motor-review) and part 1 in series of how to build your own light-weight electric skateboard.

## Maytech 70mm Hub Motors

Here are the photos of the hub motor motor components — the stator, rotor and the wheel. The rest of the photos are [available on Flickr](https://www.flickr.com/photos/kasparsdambis/albums/72157679043395564).

To buy these motors you can get in touch with Eileen from Maytech eileen@maytech.cn — and don’t forget to refer to this blog for a discount.

## FVT Sleeping Lion 120A Speed Controller (ESC)

[![Favourite FVT 120A 12S ESC for Electric Skateboard](https://kaspars.net/wp-content/uploads/2017/04/favourite-fvt-120a-12s-esc-skateboard-electric.jpg?strip=all&quality=90&resize=800,600)](https://kaspars.net/wp-content/uploads/2017/04/favourite-fvt-120a-12s-esc-skateboard-electric.jpg)

During the first test run I was using the new [high-voltage 12S 120A skateboard speed controller from FVT](http://www.szfvt.com/en/proshow-105-3-54-54-100-16-3.html). Here are the [photos of the teardown](https://www.flickr.com/photos/kasparsdambis/albums/72157681905832786).
