If you own an electric bike, there usually comes a time when you encounter issues with its functionality. This can be frustrating and cause you to think of a million reasons why your e-bike is not working. There are a lot of reasons why your e-bike could not be working but if you dive into the biggest components of the electric bike this is where the problem usually emanates from. Here are a few things you can check:


If your e-bike is not working, one of the most common reasons could be battery-related issues. Make sure the battery is properly charged and securely connected to the bike. If the battery is low or not properly connected, the bike may not work. Here are some potential battery issues that could cause your e-bike to malfunction and what to check:

  • Dead Battery: Check if your battery is charged and switched on. If it is not, charge the battery fully and try again.
  • Loose Battery Connection: Check if the battery is correctly connected to the e-bike. If not, reattach the battery to the e-bike properly.
  • Corroded Battery Contacts: Check if the battery contacts are corroded. If they are, clean the contacts with a cloth and rubbing alcohol.
  • Faulty Battery Management System: Check if the battery management system is functioning correctly. If not, take your e-bike to a professional for repair.
  • Battery Cell Damage: Check if any of the battery cells are damaged or not functioning correctly. If they are, replace the battery or the damaged cells.


There are several common motor issues that could cause an e-bike to falter. One issue could be a faulty motor controller, which regulates the power output to the motor. Check to see if the motor controller is properly connected and check for any signs of physical damage.

Another issue could be a faulty motor sensor, which sends signals to the motor controller to regulate the motor's speed and power. Check to make sure the sensor is properly connected and not damaged.

Additionally, a worn or damaged motor belt or chain could also cause issues with the motor. Check to see if the belt or chain is properly tensioned and not damaged. If none of these issues are present, the motor itself may be faulty and require repair or replacement.


The display on an electric bike shows important information such as speed, battery level, and distance traveled. If the display is not functioning properly, it can be difficult to know how the bike is performing.

One issue that can cause problems with the display is a loose connection. Check to make sure the connection between the display and the bike's wiring is secure and not damaged.

Another issue could be a damaged display itself. If the display is cracked or damaged, it may need to be replaced. Additionally, if the bike has been exposed to water or moisture, the display may not function properly.


Wiring issues can also cause an electric bike to falter. Electrical connections can come loose or wires can become damaged or frayed. If the wiring is not properly connected, the electrical signals that power the bike may not transmit properly, which can cause the bike to malfunction or not work at all.

To check the wiring, start by visually inspecting all the wires and connections for any signs of damage or looseness. Next, use a multimeter to test the voltage of each wire and connection to ensure they are functioning properly.


The controller is an essential component of the e-bike, as it manages the flow of power from the battery to the motor. If the controller fails or malfunctions, the e-bike may not work correctly or at all. The following are some common signs that the controller may be the issue:

  • The e-bike doesn't start or has no power
  • The e-bike stops working unexpectedly
  • The e-bike motor runs intermittently or at full power

To check if the controller is the problem, you can do the following:

  • Ensure the e-bike is powered off and disconnected from the battery.
  • Locate the controller box, which is usually found near the battery.
  • Inspect the controller for any visible damage or loose connections.

If everything looks fine, use a multimeter to test the voltage coming into and out of the controller. If the voltage readings are off or inconsistent, the controller may need to be repaired or replaced.
