Hello Everyone,

I recently bought a Chinese unicycle online, as soon as I turned it on for the first time it started beeping continuously with the battery LEDs ON as shown on this video:

I already tried fully charging it and calibrating it, nothing worked so far... Please, if anyone have any further information on how to solve this, share it.

Thank you all in advance.

Hi Marcello, I saw your message and it seems as you say that our problems are quite similar.

Unfortunately I could not figure out yet what's wrong with mine.
I suspect a loose HALL sensor but I could not managed to open the motor yet.
I need a bearing remover...and also mechanical is not my field of expertise.

Anyway I will keep trying and I will keep you posted.
Please do the same on your side if you manage to figure out something.
Also you should contact your reseller as they normally have engineering support team.

When I first received mine it was also not working and I had a lot of support from the seller.
Bad luck that he is now out of business...

 

Let me know.

 

Herve.

Hi, mine did the same. But only in certain positions. I think one of my hall sensors is faulty. I put my unicycle to ebike repair shop today so I will let you know how it goes. If you can I suggest measure the sensors like this https://www.youtube.com/watch?v=efYFOHnXh0E. I got the idea from jayjay23.

Hey, thanks for the suggestion. I already watched the video, I'll get the right tools and give it a try.

Please keep us updated on what the ebike guys say to you.

Hey everyone, I just solved this problem and I wanted to update you:

After I contacted the seller he sent a new mainboard. I just had to change it and it was good as new. Nothing complex about changing the main board, just unplug everything and plug back in the new one.

The anoying part of course is that I had to wait a couple of weeks for him to ship the board.

Thank you all guys for your support and good luck.
