As ebikes are used for a long time, they will make abnormal noises. Abnormal noises usually mean that there is a problem with the ebike. Finding the root cause of the problem and solving the problem as soon as possible can avoid bigger problems with the ebike, and the cost of repair will be greatly reduced. Some noises only occur when riding, and some noises also occur when stopping.
This article is classified according to the parts that make abnormal noises. If you can identify the parts that make abnormal noises, you can quickly solve these abnormal noises and complete them. You can have a clearer understanding of the parts of your ebike through this article.
Brakes - If the abnormal noise of the electric bicycle occurs in the brakes
Abnormal brake noise is a common cause of abnormal noise in electric bicycles. If abnormal brake noise occurs while riding, it is usually caused by the following reasons:
1. Dirty and worn brake pads
If the brake pads are stained with small stones or smaller obstacles, they are likely to make abnormal noises when braking, causing abnormal friction and abnormal noises. Alcohol or special cleaning agents are needed to clean brake pads, brake discs or other brake-related parts.
2. Brake calipers misaligned
If the brake caliper is not aligned, the brake pad will contact the brake disc, causing abnormal noise. If this happens, you need to adjust the position of the brake caliper so that it is in the correct position so that the abnormal noise will not be heard.
3. Brake disc not clean
If there is dirt or small objects stuck on the brake caliper, it will affect the smoothness of the brake caliper and you need to clean or replace the brake pads to solve the abnormal noise.
Pedal or bottom bracket axle noise - If you hear unusual noises when pedaling
If you hear unusual noises when pedaling, it may be caused by the following reasons. Please check your ebike as follows:
1. Crank arm or bottom bracket is loose
Long-term riding can cause parts to loosen, resulting in abnormal noises when riding. If this happens, you need to use pliers to retighten the crank arm and the bottom bracket.
2. Pedal threads are dry or dirty
Metal friction may cause abnormal noise. Insufficient lubrication on the pedal threads is likely to cause this, so you need to apply lubricant to the threads before reinstalling.
3. Bearing wear
Bearings will age or lose lubrication after long-term use, causing noise. Bearings may also make noise because they are too tight or too loose. If noise still occurs after lubrication, you need to consider whether the bearing needs to be replaced.
Chain or derailleur squeaking - If your chain or derailleur squeaking
1. The chain is dirty/lacks lubrication
The chain is dirty and will not only affect the riding comfort, but also the degree of abnormal noise. If there is a lot of dirt on the chain, it will cause abnormal noise when riding.
2. Transmission screw loose
The screws of the transmission will loosen while riding. You need to check the condition of the screws of the transmission regularly so that the transmission can run normally without making abnormal noises.
3. The transmission hanger is not aligned
If the transmission limit screws and hanging ears are not adjusted properly, the chain will jump and produce abnormal noise. In this case, the limit screws should be adjusted to ensure smooth speed change.
Frame or shock squeaking - Frame or shock squeaking guide
If you hear unusual noises while riding on a bumpy road, please check the following parts and gradually eliminate the problem with the accessories.
1. Loose frame or shock absorber screws
The metal connection may be loose, which may cause abnormal noise. You need to ensure that the metal connection is firm enough and not too tight. There may be some looseness.
2. Lack of lubrication on shock absorber bearings or pivots
Lubricate the bearings or pivots. A too dry pivot will make a noise. You can use a silicone-based lubricant to lubricate the pivots. If the frame is damaged, it needs to be replaced in time.
How to prevent abnormal noise from electric bicycles?
1. Clean your electric bike regularly
Clean your e-bike regularly, especially the brakes, chain and transmission system, and promptly clean any dirt and impurities stuck in the components, such as small stones, gravel and anything else that may cause abnormal noises.
2. Check the tightness of the screws
Check the frame, brakes, pedals and all screws from time to time to make sure all screws are firm and not too tight or too loose.
3. Use high-quality lubricants
Lubricate the chain, pedal bearings and other parts regularly to reduce friction between parts and prevent abnormal noise.
4. Proper storage of electric bikes
Electric bicycles should not be placed in a humid environment for a long time to prevent rust in the humid environment.
Summarize
Most electric bicycles make abnormal noises due to dust accumulation, loose parts and lack of lubrication. By following the above component inspections, you can effectively reduce the occurrence of abnormal noises and improve your riding experience.
