Electric Bike Troubleshooting Guide

Hey guys, I'm Euybike mechanic Tom and welcome to our guide on troubleshooting electric bikes. In this guide, mechanic Tom will explain in detail the common faults of electric bikes, how to troubleshoot electric bikes, solutions to electric bicycle faults, how to reduce electric bicycle faults, electric bicycle maintenance and other knowledge, and then follow Let's study together with Tom.

Electric bike fault introduction

E-bike, like bikes, are gaining popularity as a convenient and environmentally friendly mode of transportation. Unlike a bike, it comes with a motor, battery, and controller, and it also has pedal assist to make it easier to ride in various terrains. However, like any vehicle, e-bikes are subject to problems and breakdowns.

What are the common faults of electric bikes

Electric bikes have many parts, and maintenance is essentially the repair and replacement of parts, so Tom will explain the possible failures from the key parts. There are mainly electrical and mechanical faults, the most likely faulty parts are batteries, motors, controllers, lights, frame, front forks, handlebars, cables, brakes, throttle valves, derailleur, tires, shock absorbers, discs Brake noise, etc.

How to troubleshoot electric bikes

Tom met many bicycle beginners who didn't know what to do when the bike broke down, and they didn't know how to describe what happened to the bicycle when they went to the manufacturer for after-sales service. Next, Tom will tell you the knowledge and steps you need to solve common electric bicycle failures. By following these troubleshooting tips, you can get your e-bike on the road fast and a joy to ride.

Common fault types of electric bikes

After understanding the common parts failures of bikes, it becomes easier for us to troubleshoot electric bikes. The most common types of failures are several, such as batteries not charging, motors not working, displays not working, brake problems and controller failures.

Electric Bike Troubleshooting Steps

A step-by-step approach to identifying and resolving e-bike problems, troubleshooting steps include:

  • Check the bike frame for damage.
  • Check the battery capacity and whether it can be charged.
  • Check that the motor can rotate.
  • Check the throttle.
  • Check that the brakes are normal.
  • Check tires for leaks.
  • Check if the display works.
  • Check that the lights work.
  • Check the bike for noise.

After passing the inspection of these steps, most of the faults of electric bikes can be found. In this way, whether you repair it yourself or find the manufacturer's after-sales warranty, you can quickly solve the fault.

Solutions to electric bike failures

Broken bike frame

  • Frame tilted - replace frame
  • Severe dent in frame - replace frame

The battery won't charge

  • Battery has reached end of life - replace battery.
  • The fuse in the fuse tube inside the battery is broken - replace the fuse.

Turn on the power, the motor spins immediately

  • Throttle handle damaged - replace
  • Bad controller - replace


Bikes have noise when riding

  • Disc Brake Noise - Adjust Brakes
  • Flywheel is stuck with sand - clean the sand.
  • Shock absorber is noisy - add oil.


Short driving distance

  • Check that the battery is fully charged.
  • Aging battery - replace the battery

After learning these solutions for electric bikes, you will be able to replace most mechanics when encountering bicycle failures. Congratulations, you are no longer a beginner. You only have a little practical experience. You will solve bicycle failures by yourself . Of course, if you encounter a failure that cannot be solved, please take the bicycle to the nearby E-bike shop for repair.

How to reduce electric bike failure

  • Pay attention to the use and maintenance of batteries, chargers, electric controls, motors, brakes, controllers, and tires.
  • Do not ride the bicycle in a harsh environment, and do not expose the bicycle to the sun or rain.
  • Reduce e-bikes problems with regular preventive maintenance, proper battery care, motor maintenance, brake tuning and general maintenance.
  • Practices to minimize e-bike breakdowns, such as proper riding technique, learning the bike user guide, and safety precautions.


The Importance of Troubleshooting

Troubleshooting is the process of identifying and fixing problems with your e-bike. It plays a vital role in ensuring the smooth operation and longevity of your e-bike. By becoming familiar with common problems and troubleshooting techniques, you can save time and money by solving problems yourself, or at least gain a better understanding when seeking professional help.

In conclusion

Troubleshooting an e-bike doesn't have to be a daunting task. By understanding common faults, following proper diagnostic steps, and implementing effective solutions, you can keep your e-bike in good working order. Remember to perform regular maintenance, address issues promptly, and follow best practices to minimize problems and prolong the life of your e-bike. Enjoy the ride and happy troubleshooting!
