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.
