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

K
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.
