Fixing an abandoned Onyx RCR part 1

I bought this onyx RCR really cheap, thinking they was going to have major issues but turn out to have several minor issues.
I bought it to re-sell it so I will not keep it. But I will try to record and post the whole experience.
Every time I buy to re-sell the bikes sell so fast that I feel bad for not taking the time to enjoy them ,hopefully if I record the whole thing, I could go back and watch the video and feel better about it.
Shops are not too friendly towards fixing heavy duty high ends ebikes so I wanted to share the process of troubleshooting and fixing the ebikes so that people can do this stuff on their own.
