Why is pedaling so difficult on my Yamaha PW-X Bicycle Accessories?

  Kenneth BeanAug 13, 2025
  If you're finding it hard to pedal your Yamaha Bicycle Accessories, here's what to check: * Ensure the display unit is powered on. * Verify the battery pack is correctly installed and charged. * If the bicycle has been stationary for more than 5 minutes, try turning the power on again. * Note that on long inclines or with heavy loads, the system might temporarily reduce power assist to protect the battery or drive unit from overheating. Shift to a lower gear to alleviate this. * In cold weather, store the battery indoors before use. * Avoid charging the battery while it's mounted on the bicycle.

  If the traveling range of your Yamaha Bicycle Accessories has decreased, consider the following: * Make sure you are fully charging the battery pack until it reaches full capacity (F). * Low temperatures can affect battery performance. The normal traveling range will be restored when the ambient temperature rises. Store the battery pack indoors in a warm location before use to improve range in cold conditions. * The battery pack may be worn out and need replacement.

  If the Drive Unit of your Yamaha Bicycle Accessories turns on and off while riding, check that the battery pack is correctly installed and locked in place. If the problem continues with a firmly locked battery, it could indicate a loose connection with the battery pack terminals or wires, and you should have an authorized dealer inspect your bicycle.

  If the speed isn't displayed while riding your Yamaha Bicycle Accessories and the function display is flashing (or the assist mode lamp lights up red with an error description on Display X), the speed sensor may not be detecting a correct signal. Turn the power off and on again, select the assist mode, and ride for a short distance. Also, check that the magnet is correctly mounted on the wheel spokes.
