Generally when ebike motors are in use, there will be a slight noise. Noise occurs when you’re switching controls, partially because of the gears and magnets are cogging against each other, which is inevitable. The gears are made of Nylon, and have increased its width by 20% compared to the original design. This is to help diminish the gears from backlash and from wearing out.
The level of motor noise also varies by how fast you’re going and the weight of cargo you’re carrying. However, the noise is not as loud as a mountain bike driving on pavement with 2.1inch thick tires. To minimize the electric switching noise, our geared hub motors have a higher rotational speed so that the cogging noise is less noticeable.
