Why Is My Grizzly, or D-Class, Motor Making a Weird Noise?Updated a month ago

Hearing unexpected noises from your Ariel Rider motorized bike can be concerning, but in most cases, these sounds are normal. Below, we explain what might be causing the noise and when to seek assistance.

Common Motor Noises – What’s Normal?

• The sounds coming from your motor wheel are typically the motor turning the internal gears.
• These noises are often more noticeable in the front motor, as it carries less weight.
• Minor motor sounds do not usually indicate a problem and are part of normal operation.

When to Be Concerned

If you notice any of the following along with the noise, it could indicate an issue:
✔ Loss of performance (reduced power or speed)
✔ Shaking, pulsing, or grinding sensations while riding
✔ Sudden changes in motor noise intensity
✔ Motor wheel is not turning, but you can hear the motor running
