Andrew Blewett Posted November 23, 2019 Share Posted November 23, 2019 Hello, I'm not very handy but I love electric unicycles. The problem is that I have TWO and they're both broken, with different problems. I'm intimidated by the amount of work it takes to fix them. I have a gotway MCM5 which has a flat tire and I don't even know where to start with disassembling it to get at the wheel. I figured maybe my Kingsong 14D would be easier to work on since I've taken it apart to fix multiple flat tires (are you noticing a pattern), so I'm more familiar with it. I had to set it aside originally because it stopped taking a charge! I finally pulled enough crap off to get a look at the wires going to the charging port, and I don't know if what I'm seeing is normal. There are 3 prongs but only two have wires. Additionally, the charging cable got nicked back in the day at some point. I don't know if that could be the culprit instead. See included pictures. I'm at a loss. Riding EUC has been a game changer for me, and a major way I de-stress lately and since my wheels have been out of commission my quality of life has taken a hit.

Fuerte Posted November 25, 2019 Share Posted November 25, 2019 Where did you buy your wheels? If you bought at Ewheels then get a hold of Jason and he can help you sort it all out. 1 Quote Link to comment Share on other sites More sharing options...

It would be a new thing to do on a ”baby” of yours, so that is perfectly understandable. Many people have felt the same way, but have ended up making even deeper repairs with the help of this forum and...

Look for ”MCM5 disassembly” or ”MCM5 tire replacement”. Many people think they are bad at repairing stuff, but there are very few people that actually are bad. If you have patience to follow simple instructions, you’ll surely get it done yourself! If you completely lack patience, then it’d be best to let someone else do the work. Like the distributor you bought the wheel from, or even a local fellow rider. On 11/24/2019 at 12:42 AM, Andrew Blewett said: There are 3 prongs but only two have wires. This is normal, only two of them are in use. And the crack in the connector isn’t a problem unless it enables the connector to be put in in a wrong position (doesn’t appear so). That might do real damage to the mainboard, batteries, or even your house. At least to the fuses on the mainboard. Inspecting the KS further would require a multimeter. If you don’t have one, I’d tackle the MCM5 first. On to YouTube! Quote Link to comment Share on other sites More sharing options...
Andrew Blewett Posted November 26, 2019 Author Share Posted November 26, 2019 Thank you so much guys! I've been wondering for a while if Jason is handling repairs, I figured no because it was too good to be true. And thanks for confirming its not the plug. But the mystery deepens. Honestly I'd rather have the Gotway up and running again for the speed. Quote Link to comment Share on other sites More sharing options...

I have an MTEN power supply, which is the same one used on the 14D. The LED is GREEN and stays GREEN when I plug it into the 14D. When I connect the charger to my MTEN3, the LED turns RED to indicate it's charging, so there's no issue with the charger. Any tips on how to fix the 14D not charging is much appreciated. TIA!

Are you absolutely sure that the Mten charger has the same voltage (67.2V) and pinout? If the charger is of a correct type, what is the current voltage on your 14D?
