Electric bikes are not particularly fragile and are generally reliable. However, a breakdown can still occur. Should you check the motor or the battery? Is the issue with the controller or the transmission? The causes can be varied. In this article, we help you identify them so you can resolve the problem more quickly.

Power supply issue: battery, contacts, and cables
When your electric bike stops working, start by checking the power supply. Ensure that the battery is charged and properly secured. There should be no loose connections. Also, check the contacts and various cables.
Oxidized contacts are one of the most common causes of failure in electric-assisted bikes. Also, verify the integrity of the cables and ensure that the e-bike's display is securely mounted. If the display turns on, check the information shown, as it can help identify the cause of the problem.
Depending on the manufacturer, error codes may be displayed. To decode them, consult the user manual of the electric bike.
Battery issue: reset or replace?
You may need to reset the battery of your electric bike if it shows signs of weakness or if you are unable to restart your e-bike. Below, we explain how to reset an electric bike battery.
Allow your battery to fully discharge. You may need to reset the battery if you have forgotten to charge it regularly. Perform a full charge without interruption. Repeat the discharge and recharge cycle. Update the software if the electric bike manufacturer provides this option.
Sometimes, the battery can be reset by adjusting the settings on the bike’s display. If the battery still shows signs of weakness, it may need to be replaced. We recommend contacting the manufacturer or a specialist repairer of the brand.
Unusual noises from the electric bike’s transmission
Clicking and squeaking noises often concern cyclists. If your electric bike emits unusual sounds, you may visit a repair shop. But first, check the transmission. The chain should be clean and lubricated. A few drops of chain oil can work wonders when electric bikes make noise.
Squeaking noises may come from the fastening between the motor and the frame. Tightening the screws can fix this issue. The process usually requires removing the motor cover, so we recommend making an appointment at a repair workshop.
A transmission issue can also manifest as slipping when pedaling, where you feel like you're pedaling in vain. The chain may be slipping, possibly due to a poorly adjusted derailleur, resulting in imprecise gear shifting. Check the hub and derailleur. Adjust the screw at the gear shifter.
If you have already ridden your electric bike extensively, the drivetrain may be worn. The kilometers covered with electric assistance contribute to increased wear. Lack of maintenance and prolonged use at high speed can lead to premature wear of the derailleur.

Electric Assistance Failure
Sometimes, your electric bike turns on normally, but the assistance does not engage. The first steps to take are those we previously recommended: checking the battery and the information on the control screen. When the motor does not provide electric assistance, the speed indicator remains stuck at 0 km/h.
Make sure the power switch is turned on. If your electric bike has an ignition key, check that it is properly inserted. These are simple steps, but in many cases, they can solve the issue with the electric assistance.
If our previous advice did not help you find the problem, it is time to inspect the motor. When riding on trails or even in the city, it is common to pick up debris (branches, leaves, etc.). These can prevent the motor from functioning correctly. Make sure to clean your electric bike regularly after your rides.
Finally, if the motor appears damaged, contact customer service to get technical assistance.
