VTB Surron Light Bee Belt Wheel Synchronous Pulley Off-road Motorcycles Dirt Bike Electric Vehicle SURRON Parts

- Background -

After the earliest light bee burst change power, the belt is easy to break, and then the carbon fiber belt, the life is very long and durable and hard, the belt hardness comes up when the belt pulley is worn quickly, a month or two will be ground into a sharp, it is easy to scratch the belt leading to the belt break.Because the official aluminum alloy pulley is very soft and not wear-resistant, we designed and produced No. 45 steel pulley.

- About hardness-

The hardness of No. 45 steel is three times that of aluminum alloy, which is the same material as the small pulley of the original motor. It uses professional blackening process to prevent rust and is very durable.

- About the weight-

The original weight is 188g, our first generation design weight is as high as 860g, in order to reduce weight, we use mechanical simulation limit weight, designed the second generation of products, the weight came to 390g, only 210g heavier than the original factory, it is not easy.

- About life-

The small steel pulley of the original motor has been used for 6 months in the state of explosion, and there is still no great wear and tear. The large pulley has a much smaller force than the small pulley. With the same material, the life will be longer, and the life is expected to easily exceed 1 year.
