As a convenient and environmentally friendly means of transportation, the safety of electric bicycle is one of the most concerned issues for cyclists. Among them, the 

performance of the brake system is directly related to the safety of the rider's life. This article will introduce the basic knowledge, maintenance and use skills of the 

electric bicycle brake system in detail, to help the majority of electric bicycle users better understand and use the brake system to ensure the safety of each trip.

1. Type of electric bicycle brake system

There are two common braking systems for electric bicycles: disc brakes and drum brakes.

Disc brakes: Disc brakes are widely used for their excellent braking performance and response speed. It consists of a brake disc, brake calipers and brake pads. When 

the brake handle or pedal is operated, the brake fluid transmits pressure through the pipeline, causing the brake pads in the brake caliper to clamp the brake disc, 

creating friction to slow down or stop. Disc brakes are divided into mechanical and hydraulic types, the latter being more common because they are more sensitive 

and easier to maintain.

- Drum brake: Drum brake structure is relatively simple, low cost, and easy to maintain. It works by expanding the brake shoe inside the brake drum and rubbing against 

the drum wall to achieve the deceleration effect. Although drum brakes do not dissipate as well as disc brakes under continuous high-intensity use, they are sufficient 

for daily urban riding.

2. Maintenance of brake system

- Regular inspection: Check brake lines/tubes at least once a month for wear, slack or oil leakage, brake disc/drum surface for dents or uneven wear.

- Cleaning and maintenance: Use a clean cloth to clean the dust and impurities on the surface of the brake disc, avoid using corrosive cleaners. For drum brakes, dust and 

debris in the brake drum should be cleaned regularly.

- Adjust the tightness: according to the instructions of the user manual, adjust the travel of the brake handle or foot properly to ensure that the brake response is rapid and 

not tight, so as not to affect the normal rotation of the wheel or cause excessive wear.

Replacement of worn parts: brake pads and brake discs (drums) are worn parts, and should be replaced in time when serious wear is found or the braking effect is significantly reduced.

3. Use techniques

- Predictive braking: Predict the road conditions in advance, slowly increase the braking force, and avoid emergency braking, which can not only improve driving safety, but 

also reduce the impact on the brake system.

- Balanced use of front and rear brakes: Where possible, balanced use of front and rear brakes can slow down more smoothly and reduce the risk of skidding. In an emergency, 

the braking force of the front brake is stronger, but attention should be paid to the control intensity to avoid rollover.

- Use in dry environment: in rainy days or when the road is wet, the braking distance will be extended, and the distance between the front car and the front car should be 

increased in advance, and the brake should be used gently to avoid side-sliding caused by sudden braking.

Through the above introduction, it can be seen that the brake system of electric bicycles is not only related to riding safety, but also needs the correct use and regular 

maintenance of riders. I hope that every electric bicycle user can pay attention to the inspection and maintenance of the brake system to ensure that every ride is at ease.
