I finally got this bike finished. :D

As I wanted to use the original nice chunky sheaf, it was a real pain getting the new wires through, but I eventually managed it.

All cables fit inside the controller box...

I also made a rubber seal to poke the wires through, which should limit the amount of water that can splash up into the controller box. View from underneath...

All done...

I am pretty pleased with how this turned out, in fact the bike rides better than my own! :rolleyes: I just need to align the rear speed sensor, make sure everything is clean and lubed and all screws/bolts are tight.
Interesting project. How did you wire everything up in the end? You left a lot of your own questions unanswered!

Sorry, I thought I covered most of it.

It was a while ago now but from memory, everything was replaced except the motor and battery. I made up a new wiring harness from the motor to controller and from the battery to the controller. It was easy to work out the phases from the original controller. The extra wire in the motor connector seemed to be a temperature sensor and as the controller didn't support it I ignored it.

If there is anything specific you would like to know, let me know and I will do my best to answer.

Regards,

Les
