Thank you for your support.

Update!
This design proved to be impractical due issues with the drive train. The alternator motor has little torque so needs some kind of gearbox. For this reason I shelved this project and moved on to a hub motor and I DO NOT recommend you follow this build unless you have access to a suitable gearbox.

In this video show a couple of upgrades made to the old ebike then I start building my 2nd DIY Ebike using a car alternator.
This time I'm using a freewheel crank which I sourced from a company called SJS Cycles

Controller
This is a similar controller to the one I used though as sellers constantly change products over time I cannot guarantee it will work with an alternator. My experience is the cheapest controllers will work and the more expensive ones will not.

18650 Cells
If you are looking for 18650 cells to build a battery pack here is where I buy mine. I have always used LiitoKala cells and found them to be good quality.
Note the Name brand cells are copies, they are NOT genuine but do have similar properties to the original and are still excellent batteries.
