Short Version:
I have two ebikes from Ancheer and after less than a week of having them, neither will turn on anymore. The batteries are fully charged and display one red light and three green lights, as I'm told they should. Any ideas as to what could be causing this?
Long Version:
Hello, I am new and this is my first post. My mom bought two mountain bikes, an Ancheer Sunshine and an Ancheer Blue Electric, from Amazon back in February. I put them together for her and we have been enjoying them ever since. I decided to get a couple and ordered the same bikes from Amazon. The bikes both arrived last week. Here is where the issues began.
We got the Sunshine first and put it together without any issues. I charged the battery overnight (8 hours) and went to take it out for a test ride. It turned on fine, but when I hit the throttle, it accelerated for maybe a second or so before it just cut off completely. The meter doesn't show any lights, the throttle does nothin, and, pedal assist does nothing. I couldn't get it to turn back on. I was thinking it was a bad battery.
The next day, the Blue Electric arrives. I put it together, charge the batter for 8 hours, take it for a ride and it works great. I noticed the batteries look exactly the same, so I decided to do some troubleshooting. I put the newest battery onto the Sunshine and it turns on. I was inside and couldn't test ride it, so I just lifted up the rear tire and held the throttle to see if it would cut out like before. It ran fine inside. I figured the originally battery must've been bad, so no big deal.
Later that day, I take the Sunshine out for a test ride with the "good" battery. It turns on, but when I hit the throttle, it does the same thing as last time, just turns off and wont turn back on. I take the "good" battery, put it on the Blue Electric and it works fine. At this point, I figured it was the motor or meter on the Sunshine that was causing the issue.
The next day, after charging both batteries to full capacity, I put the "bad" battery on the Blue Electric to verify that the battery works and that the problem is only with the Sunshine. As expected, it would not turn on. However, when I put the "good" battery on the Blue Electric, it won't turn on either.
Now I have two bikes that will not turn on. I have pulled apart and re-connected each of the wired connections to make sure they are connecting well. I don't see any corrosion or damage inside of them. Has anyone had issues like this? How did you resolve them?
I can't even imagine how this could happen. It is like, the Sunshine's problems were contagious and the Blue Electric caught it. (I know that isn't how it works, but that is my best explanation.)
I have been in contact with the seller through Amazon but I only get one response a day since I believe they are in China and are working while I am sleeping, and vice versa. They have requested videos of each of the issues I have had. I have sent them for review, but haven't received any instructions on things to try or what the issue might be. They did say it might be a bad meter. I considered getting a battery from my mom and testing that out on my bikes, but I'm afraid it may "corrupt" her battery too.
