Part 1 DIY E-Bike using car alternator, laptop batteries and cheap Chinese controller.

I built this E-Bike using car alternator, old laptop batteries and cheap Chinese controller. The bike was an old one that hadn't been ridden in years, the mounting bracket was made from another old bike front and rear forks and bits of old metal I had lying around. Cost so far Bike £0 Batteries £0 Controller £44 Throttle £14 Alternator £15 Connectors, cable etc £15 Belt £11 Total £100 Fun had Priceless I will need to buy a BMS's for the batteries but it will still be just over £100 all in which I think is pretty good. I've already learned a heck of a lot about E-Bikes, batteries etc which was the main aim of the project and had loads of fun doing it. I've been asked to put a link to the controller but it is no longer available so I'll link to the sellers shop and you can check out his stock yourself. He still sells other controllers advertised as working with or without Hall. My second ebike used a 1500W controller which was described as "Hall only" but it still works great without Hall effect sensors on a similar alternator motor. I suspect most of these controllers will work just fine on a motor like this. The 1500W controller used in my second ebike build was chosen because it was cheap. https://www.ebay.co.uk/itm/24V-60V-1500W-Electric-Bike-E-bike-Scooter-Brushed-Brushless-Motor-Controller-ST/253823287117?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 Check out the videos of this build in my Youtube channel.
