Most commercial hub motor ebikes, and many kit motors come with quick disconnect motor connectors, which helps a bit for fixing flat tires. I believe the Ancheer decided to save a dollar and doesn't have a quick disconnect. My flat kit, which is only for out-of-town includes a 17 mm wrench, and a linear tube. The latter allows me to change a flat w/o removing the wheel, although the old tube would have to be cut or pulled up around the frame til I got home.



Never had a flat on the rear tires since we started ebiking. No bushes with goats head thorns where we live. Plenty of potholes though. I've had pinch flats on the front tires.

The dropout slot on a standard bike is 10 mm wide, since bike axles are 10mm in diameter. Motor axles are 12mm, with two sides ground off to allow it to fit in a 10mm slot. That means the slot might need to be cut deeper by 1-2 mm. For a front fork, there might not be enough material to safely lengthen the slot.
