How Can I Fix An Electric Bike That Won’t Start?

To fix an electric bike model that would not work make sure that the battery has sufficient power. At least two bars of power are required to start the bike. Start by inspecting the handlebar assembly. If there are any loose wires or damaged electronics, fix them before continuing.

You might think that if your electric bike doesn’t start, there isn’t anything you can do to fix it. However, there are actually several reasons why your e-bike won’t turn on. One of the most common problems is bad wiring. Wires should never come in direct contact with each other, so if you notice any loose wires, you’ll need to secure them properly.

Another common issue is a faulty connection between the battery and the controller. If you notice any broken connections, you’ll need to replace those parts.

A third possibility is a fault with the battery itself. If you notice any bulges or damage, you’ll need to change out the battery.

Finally, you may have a malfunctioning component on the controller board. If you notice any flickering lights or strange noises, you’ll need to repair the circuit board.

To find out why your electric bike won’t start, examine each part of the E-bike and look for signs of trouble. Once you’ve identified the cause, you’ll be able to fix the problem quickly and easily.

Why Your E-Bike Isn’t Working?

Electric bikes are great for commuting, running errands, getting exercise, and exploring new places. However, if your e-bike doesn’t start, there may be a number of reasons why. You’ll want to start at the bike handlebars and work your way down to the rear wheel.

Here are six common reasons why your electric bike won’t start and how to fix them.

Low Or No Battery Charge.

Your electric bike may not turn on because there is no battery charge left. You’ll notice a low battery indicator light on your bike, which means that the battery power level is low and it needs additional power to run the bike wheels.

To fix this problem, you must recharge the battery. Follow these steps to troubleshoot your electric bike battery:

Step 1: Remove the battery cover.

Step 2: Disconnect the cable connection.

Step 3: Place the battery terminal connectors onto the battery terminals.

Tip: Be careful not to touch the negative (+) terminal with your fingers.

Step 4: Connect the positive (+) terminal connector to the positive (+) battery terminal.

Step 5: Reconnect the battery cables to the battery terminals.

Repeat Steps 1 through 5 until the battery indicator light turns green.

You can now safely store your electric bike.

The Sensor And Spoke Magnets Are Not Aligned.

This is a simple problem to solve if you just look at the manual. However, it’s not uncommon for people to overlook this issue. Many people don’t realize that the sensor and the spoke magnets must be aligned correctly for the E-bikes to function properly.

You’ll notice that there is a small gap between the two components. The position of the spoke magnet on your wheel needs to be the same distance away from the sensor on your bottom bracket. If the two parts are misaligned, you won’t receive any data from the sensor.

Before you start troubleshooting, check your manual. It will tell you the exact distance required for the magnet to be placed from the sensor. Don’t forget to wash the area where the wires connect to the sensor and the battery attachment. Washing and drying this area helps to prevent corrosion and keeps the connections strong.

Once you’ve checked the manual, align the magnet on the sensor by turning the wheel until the magnet is in line with the sensor. Then switch off the E-bike and test whether the sensor works. If the sensor doesn’t register, you’ll need to adjust the position of the magnet on the sensor.

If you still experience problems, try cleaning the sensor again. Dirt and grime build up in this area, which affects the signal sent to the computer. Wash and dry the sensor before you attempt to reattach it to the bottom bracket.

The Electronic Braking System Won’t Release.

Some electric bikes are fitted with electronic braking systems, or the brake hand grips are sticking, which could prevent the brakes from releasing.

Sometimes, if the battery power isn’t sufficient enough, it will close the brakes, locking the wheels preventing free movement, and stopping you from cycling.

Or, the brake cables are too tight and close the brake pad to your wheel.

The best way to troubleshoot any problems is to check all the connections running to the braking system and the electrical display system on your bike.

If you’re confident, you can loosen the disc brakes and free the wheels, improving the issue for you to cycle home, where you can take your e-bike to your local dealership for an adjustment.

Additionally, make sure your Ebike battery pack is sufficiently powerful to power the bike and its electronic braking system. Lack of power cause problems.

E-bike Motor Or Battery Contain Water.

If your E-bike won’t start, there may be plenty of water in the motor or battery. You should remove the battery cover, open the terminals and drain any excess water out of the battery. Then clean the terminals and reattach the battery connection.

Most E-bikes come with a waterproof bag that keeps water away from the battery. However, if you find that the battery still doesn’t work after cleaning the terminals, then you might have a problem with the battery itself.

You can test whether the battery works by plugging it into another device. If the battery works fine, then you’ll probably need to replace the battery.

Most electric bike manufacturers will attempt to prevent water gases from entering their motors and batteries. Water results in swollen battery packs.

Error Codes Showing Up On The Computer Screen.

An error code appearing on the computer screen means that something isn’t working correctly. Sometimes, this just means that the bike needs to be taken to a repair shop. However, sometimes the issue is serious and requires immediate action.

For example, if you see an error code showing up on the computer screen, you should stop riding immediately and call your local bike shop. If the error code shows up repeatedly, it may indicate a problem with the motor, display unit, or battery pack.

You’ll find that the error codes shown on the computer screen are usually accompanied by a description of the problem. Read through the descriptions carefully and look for any additional information that might help you identify the cause of the problem.

After reading the descriptions, apply the actions suggested in the manual to correct the problem. If your bike is covered by a warranty, do not attempt repairs yourself. Instead, take it to your bike dealer.

If you try and fix the issue yourself, your warranty will be voided, and it could cost you money.

Riding The Electric Bike Before The System Turns On.

Before you start riding your e-bike, make sure that you turn on your battery and your computer display unit. Give it a couple of seconds for the display unit to activate and for the computer to run through its initial checks. You don’t want to start pedaling before the system is fully powered up and running properly.

You should never try to ride your e-bike before it’s fully charged. Doing so could damage the battery and cause the system to fail to turn on.

Instead, wait until the system is fully charged and functioning properly before you start pedaling. Once you’ve started pedaling, you’ll notice that the power level increases automatically.

This process helps protect the capacity of your battery and allows the system to operate and work properly.

E-bike Still Failing To Start?

If your e-bike still won’t start after examining each part of the EBIKE, you’ll need to fix the problem. There are several possibilities for why your e-bike still isn’t starting. You’ll need to identify the reason and then fix the problem accordingly.

First, you’ll need to determine whether the issue is caused by a faulty connection between the batteries and the controller. If the connection is damaged, you’ll need to remove the battery and connect it directly to the controller. Then, reconnect the battery to the controller using the proper connectors.

Next, you’ll need to inspect the battery. If you notice any damage or bulges, you’ll need to exchange the battery for a new one.

Finally, you’ll need to examine the controller board. If the board is damaged, you’ll have to replace it.

Once you’ve determined the reason behind your e-bike not turning on, you’ll be able to fix the problem quickly and efficiently.

If you notice that your E-bike is making a clicking sound while pedaling, this means that the motor is running properly. However, if you hear nothing at all, then the motor is probably broken.

If you suspect that the motor is faulty, take it to a professional mechanic who can test the motor and give you a quote for fixing it.


Fixing an electric bike that won’t start requires examining each part of the machine and identifying the source of the problem. You’ll then be able to fix the issue quickly and easily.

A lot of times, we don’t realize that our bikes are not working correctly until after we’ve ridden them for a while. By then, it’s too late to fix the problem. So, if you notice any issues with your bike, stop riding and investigate the problem right away.

To determine why your electric bike won’t start, examine each part individually and look for signs of malfunction. Once you identify the cause, you can fix the problem quickly and efficiently.

Electric bikes are becoming increasingly popular. You can now buy an electric bike at almost every store that sells bicycles. There are two main types of electric bikes: pedal assist and throttle control. The pedal assists electric bikes to require no pedaling, whereas throttle-controlled electric bikes require you to pedal. Both types of electric bikes are great for commuting and fitness.
