      If you have a crowded handlebar, try shuffling components around to create space. Alternatively, consider using a thumb throttle.

      If there isn't enough thread extending out the other side of your bottom bracket (10mm+ required) or the motor won't slide in due to a small diameter, you may need assistance from a bicycle mechanic.

      Ensure your bike has an internal bottom bracket between 68 and 73mm wide for compatibility. If there are small defects like burrs, smooth them out with a file.

    How to troubleshoot a BAFANG Bicycle kit that won’t turn on?
    • M
      Miss Tiffany Parks MDAug 28, 2025
      If the kit won’t turn on, use a multimeter to test the DC voltage output from the base of the battery. For a 36V kit, the voltage should be over 41V. If it's not, the battery may need testing and potential replacement.

    How to fix a high pitched rattling noise when accelerating on my BAFANG BBSHD?
    • C
      Claudia DawsonAug 27, 2025
      A high-pitched rattling noise during acceleration may be due to loose parts. Check if the noise comes from the motor or from loose components like spokes or bolts on the rear rack. Tighten any loose parts to resolve the issue.

    What causes my BAFANG BBSHD Bicycle battery to cut out intermittently?
    • K
      kelsey02Aug 25, 2025
      Intermittent battery cut-outs can happen if the battery is low on power or if you're going up a steep hill with a load on the motor. This can cause a voltage cut-off due to an overloaded controller.

    Why my BAFANG BBSHD Bicycle kit loses power over bumps?
    • A
      Austin BurnsAug 23, 2025
      Losing power over bumps can occur if connections are loose. Check all connections to ensure all plugs are fully connected. Also, verify that the battery is securely locked to the cradle and not loose.
