What are the core advantages of bicycle belt drive system?

The core advantage of bicycle belt drive, with an objective short board to facilitate the comparison of chains.

First, the core advantages

1. Maintenance-free and maintenance workload is extremely low.

No need for regular oiling, no sediment and no dust adsorption; There is no problem that chain oil pollutes trouser legs and vamps.

There are no processes of chain elongation, frequent chain cutting and chain cleaning; Normal use of tens of thousands of kilometers without maintenance.

The most prominent advantages of commuting and long-distance travel.

2. Quiet operation and small vibration.

The belt is made of polymer composite material, and the noise of meshing operation is much lower than that of metal chain; When riding at high speed, you can hardly hear abnormal transmission noise, and there is no metal noise caused by friction and impact between the chain and the flywheel, so it is more comfortable.

3. Clean and free from oil pollution

Dry transmission in the whole process, no oil splashing or rubbing. City commuters don't have to worry about getting dirty when riding in formal clothes and tooling, which is an outstanding advantage that chain drive can't match.

4. Smooth transmission and small impact

The belt is more flexible, and the transition of starting and pedaling force is soft; Compared with the chain, the bite impact is lower and the riding foot feels smooth.

5. Resistant to corrosion and humidity

Not afraid of rain, muddy water, sea salt spray environment; It won't rust in the rain like a metal chain. Suitable for riding in rainy areas and coastal areas.

6. Stable service life (under the premise of correct use)

High-end carbon fiber core belt, normal commuting can reach 20 thousand to 40 thousand kilometers; Far better than the ordinary chain (the ordinary chain needs to be replaced when it is 5000～10000km).

7. Simple structure and neat appearance

No exposed chain, no chain guard, clean vision of the whole vehicle; Many city cars, retro cars and electric power-assisted bicycles are preferred.

Second, supplement the key limitations (selection must be known and balanced cognition)

Can't change speed (traditional belt drive is mostly used for single speed/internal speed change hub), and can hardly adapt to external speed change system;

It can't be connected on site after breaking, and the chain can be connected temporarily for emergency. If the belt is broken, it can only be replaced as a whole;

The upper limit of load is limited, and belt jumping is more likely to occur in violent sprint, off-road heavy load and high-intensity riding in mountainous areas;

The whole transmission cost (belt+special front and rear toothed discs) is more expensive than the chain kit;

Strict installation requirements: the tension must be accurately controlled, and the bearing resistance must be increased by too loose and too tight.

III. Summary of applicable scenarios

Best Scenes: Urban Commuter, Retro Bike, Internal Variable Speed Station Wagon, Urban Electric Bicycle.

Not suitable for: mountain cross-country, racing road bike, heavy-duty long-distance cross-country
