Electric bicycles are very convenient for daily use, but sometimes you may encounter issues where the bike fails to start. If your electric bicycle won't turn on, don't worry too much—the issue could be caused by a variety of common problems. This article will guide you through how to check and resolve these common issues to help you get your electric bike back up and running.
1. Check for Insufficient Battery Power
First, confirm whether the battery has enough charge. The battery’s power indicator or display is usually located on the battery itself, the control panel, the handlebar display, or the smartphone app. These indicators allow users to check the battery's charge in real time, preventing the issue of insufficient charge causing a failure to start. Check the remaining battery level through these indicators. If the battery charge is too low, use the original charger to charge the battery, ensuring it is fully charged. During the charging process, pay attention to the charging indicator light or the charging status on the screen.
If the battery is completely drained, allow it to charge for a period of time before trying to turn the electric bike on again. If the bike still won’t start after charging for a while, and the battery isn’t charging, the battery may be faulty and might need replacement.
2. Check for Battery Damage or Aging
Batteries have a limited lifespan, and after prolonged use, the battery may age or become damaged, leading to improper power supply. If your electric bike has been in use for many years, especially with frequent charge and discharge cycles, the battery may have lost some of its capacity and the voltage may have dropped.
Inspect the battery for signs of swelling, leakage, or deformation. If you notice swelling of the battery casing or any liquid leakage, the battery is damaged and cannot be restored to normal use. In this case, you’ll need to replace the battery.
3. Check for Poor Battery Connections
Check these four contact points:
1. The interface where the battery connects to the frame
2. The connection between the battery and the electric bike's electrical system: this interface is usually at the junction between the battery and the frame, or near the electrical system.
3. Internal contact points within the battery pack: if you suspect there may be a problem with internal contacts, it is best to have a professional check it to avoid dismantling it yourself.
4. The battery charging port and the charger interface.
The battery connections to the electric bike could be the source of the issue. If there is poor contact or contamination, oxidation, or dirt, the battery's current may not flow smoothly, preventing the bike from starting.
Check the contact points of the battery to ensure that the connectors are not loose and that there is no oxidation, dust, or dirt. If there is dirt or oxidation, clean the contact points with a clean cloth and appropriate cleaning agent. After cleaning, reinsert the battery, ensuring the connection is secure, and try to start the bike.
4. Check for Controller Faults
Check if there are any fault indicator lights or error codes on the controller. Most controllers have one or more indicator lights located on the front or side of the controller's casing. These lights usually display the operational status of the electric bike or any faults, with different colors or blinking patterns indicating specific issues. If the light turns red or blinks, and the error code starts with an "E," it could indicate a fault in the controller.
In this case, try restarting the electrical system: disconnect the battery from the controller, wait for a few minutes, then reconnect. If the issue persists, it is recommended to contact a professional repair technician to inspect or replace the controller.
5. Check for Motor Faults
The motor is the core driving component of the electric bicycle. If the motor fails, the bike won’t start. Check if the motor's cables are loose or broken. You can lightly shake the motor connections to see if there are any loose connections. If the motor makes unusual noises or is visibly damaged, it may need to be replaced or repaired.

6. Check for Faulty Start Switch or Power Switch
Check if the start switch or power switch is functioning properly. Sometimes, an electric bike may not start due to a faulty start switch or poor contact in the power switch. First, try restarting the bike by turning off the power, waiting a few seconds, and then turning it back on to see if it starts properly.
If the start switch or power switch is damaged, it needs to be repaired or replaced. Most electric bike start switches are relatively simple, and you can inspect them for any looseness or damage. If necessary, you can contact customer service to have it replaced.
7. Check for Blown Fuses
Electric bicycles are often equipped with fuses to protect the battery and electrical system from overloads or short circuits. If the electric bike won’t start, check if the fuse has blown. If the fuse is blown, the current won’t be able to flow normally through the bike.
Steps to check the fuse on an electric bike:
1. Find the fuse location: Fuses are usually located near the controller, battery management system (BMS), or within the battery box. It’s best to leave this part to a professional because there are many types of fuses, and you may not be able to identify the correct one yourself.
2. Turn off the power and disconnect the battery: Make sure the electric bike's power is off, and the battery is disconnected to avoid electrical damage.
3. Inspect the fuse:
Visual inspection: Look for any breaks in the fuse or signs of burn marks.
Use a multimeter: Set the multimeter to "continuity" mode and test both ends of the fuse. If the resistance is zero or you hear a beep, the fuse is working fine; if there’s no sound, the fuse is blown.
4. Replace the blown fuse: Replace it with a new fuse of the same specification.
5. Test the bike: Reconnect the battery and check if the electric bike starts properly.
If you confirm that the fuse has blown, you can purchase a fuse with the same specifications or contact a professional to replace it. Do not replace the fuse yourself, as improper installation may cause circuit issues or further damage to the commuter electric bike. A professional will ensure that the correct fuse is used and installed properly to guarantee the bike's safety and proper operation.
