The QiCycle Folding Electric Bike is Xiaomi’s first foray into the world of e-bikes. It has a 250W high-speed motor powered by Panasonic 18650 lithium batteries. The Shimano Nexus 3-speed gear hub in combination with the torque measurement sensor gives you up to 45km bike power on a single charge. It also has a trip computer can connect to your smartphones via their special app and is–of course–foldable.

Where can I buy spare parts of Mijia QiCycle Folding Electric Bike?

I live in Vietnam and the chain tensioner of the bike separated and I could not find it. Now I can not ride my bike without the part. Please tell me where to buy spare parts of this bike. I tried many times sending emails to dealers in Vietnam (unauthorized dealers only) and even Xiaomi Global website but they all did not reply. Please kindly tell me where to buy it on amazon or from similar methods. Please help although this question does not seem to relate to the topic. Thank you very much for your response.

I would have a better one made, or make it yourself if you have that availability of a few tools and some technical savvy or sort of thing.

A local backyard mechanic or junkyard for bikes/light trucks will have plenty of parts that could be converted- these guys can fix you up.

If you own an ebike you (Similar to a Harley Davidson owner) should have a working knowledge of how to diagnose and fix your ebike/e-scooter.

There are websites like 'endless sphere' that can give you some tips if you have time to read as most ebikes are quite similar with 3 types of motors and 3 types of batteries needing 3 types of chargers. The type of motor and the controller is important if you want to consider upgrading to make it faster perhaps you must know your motor although endless sphere may be only a starting point.

I would try local Kijiji site and see if anyone is fixing or parting out bikes usually anyone buying that stuff will also sell it and fix you up.

Keep on Rollin'

Hope it helps.

P.S. I plan on posting my newest find an $80. Ebike on Kijiji & I diagnosed & quicky-Fixed fixed in 5 minutes but now I have to assemble the partially taken apart bike because the person didn't know what they were looking for and tore the controller out (he called it a computer) and it was a simple fix because I moved the back wheel and it jerked when it moved and yiu would have a hard time trying to push this bike or make it go. It was only one shorted wire doing this. It may be a week before I get this Ecoped Citygo bike on endless sphere bcuz I have many pics and a lot more assembly work so it may be in parts.

Thank you John DoeIT very much for your link. Thanks to your link, I now could find the right stuff for my electric bicycle. I didn't even think I would be answered someday, because Xiaomi has several times failed to get back to me as they promised right after receiving my request for help. I would never buy any Xiaomi product again. No spare parts. No customer support.
