So I thought I'd start a different thread for my new "eZuma" as opposed to the petrol-sipping "JayZee".

I'll start with a photo from day 1 -- directly after picking up via Craigslist.

Notice the heavy use of decorative plastics and decals.

Not to my taste. Those will have to go. I like my bikes naked!

So 24 hrs later, my busy hands were happy to remove the extraneous decorative plastics and decals. Note: it was easy to remove the decals: 20 secs each with a heat gun was enough to loosen 'em up, then just peal away.

This "bare bones" state is where I begin the journey.

First things first. One must understand the wiring you are dealing with.

I spent about 2 hrs cleaning up the tangled mess that goes for Chinese wiring in these bikes.

At this point, I actually think I understand how most of it works! :P

The other thing you discover is that the Chinese "engineers" are sending 72v up to the handlebars! ("We don't need no stickin' relays!")

This is why I am going to start by replacing the controller first -- I want to rewire everything anyway so I might as well "get it right" first time around. Later I will add a more powerful motor (from the same manufacturer QSmotor) then last-but-not-least, replace the battery pack. It might take me a year or more to complete, but I will begin this fall with the controller and wiring.

Sounds like you have the plan,  now I know why guys are always complaining about Chinese wiring, I didn't realize it looked like that.
