Hi,
I started to work on my ATV conversion about 4 years ago (with a lot of long pauses), finally last week I could do the first test:

The ATV is a Jianshe 250 bought about 10 years ago for 2000€
Motor: used ME1114 with regular hall sensor instead of the sin/cos, with a pulley and universal joint to the original transmission shaft
Controller: Sevcon gen 4 size 4 on ebay, with the old IXXAT interface (I don't sell it !)
Motenergy provided me a configuration file they use on a test bench, it was certainly not easy to make it working but I didn't had to modify the difficult settings such as the PI control loop parameters.
Batteries: 10Ah headway cells to form a 72V 60Ah pack
I have also 4 headway cells for the accessory battery and a 12v converter
BMS: the last model from foundingpower bought before they stopped
Throttle: I used a thumb throttle modified with 3d printed parts to use a cable so I can keep the original thumb throttle
Everything fits very very tightly:
