Ebike not turning on

Being prepared for your e-bike is more than just good practice. It’s a necessity, like any machine. It’s an electronic and mechanical device that can encounter issues.
A few years ago, I encountered an issue with my e-bike, as one does. I was pushing the power button, but it was not working.

The white LED screen showed the company logo when I pressed the powered button after a while- the screen flickered for a few seconds, and then it turned off. Basically, it automatically shut down and was not able to restart. After searching for hours on the internet & talking to my community of friends who had e-bikes at that time, I figured that the main wire going toward the controller was loose.

Because it was loose, it would get connected for a moment and then disconnect, which was obvious- seeing that there was complete shutdown in the bike, I should have connected the dots & realised the fault is with the power cables.

FIRST, LET’S FIGURE OUT WHY YOUR E-BIKE IS IN SHUT DOWN, OKAY?

To figure out why your e-bike is shut down, we first need to go through a maintenance cycle. Once the diagnosis is incomplete, we will most probably know the culprit & get it sorted. Lessgo-

1. First, unplug the wires and check the pins; inspect them properly to see if they are damaged or fitting correctly.
2. Check the wire connection between the LCD screen and the primary wire.
3. Check the primary wires plugged into the controller to see if the pins on the handlebars, buttons, and LCD are in good condition and undamaged, as the damage might cause a malfunction in your e-bike.
4. If all these are fine, your e-bike might have a power problem.
5. By the term POWER PROBLEM, I mean the battery problem, so the next thing to do is check the battery current flow.
6. Just try to check the pins of your e-bike battery to see if the male connector is connected properly to the female connector. After a long time, it gets rusted, and the power flow is improper.
7. VERY IMPORTANT—please remember to check the fuse of your battery. It might get blown, so just replace it with a new one.
8. Also, watch this video to understand the battery testing process via voltmeter. A voltmeter is an electronic tool that will help you determine whether your battery can hold its full charge or is starting to degrade.

Finding the controller and resetting it:

I remember the day when I was out and about running errands & meeting friends for coffee to discuss our love for e-bikes for a long time- I faced the same problem again. I asked one of my very good friend who had a good experience with the technical aspects of e-bikes- you can call him my early mentor.

He introduced me to this process, and I followed it. It worked for me. Since then, I have used it for countless e-bike owners in my morning club & time to time for myself; I suggest you give it a try, too-

• I will start with the basics- so let me explain the term controller so you can get a rough idea. The controller is a device or sensor that controls the primary functions of the e-bike, such as Pedal Assist and total power output, according to the throttle response.
• Second, unmount your battery if it’s removable. If not, try to unplug all the wires from the battery so you don’t get any shock while handling the controller.
• Third, find the exact location of the controller. They are mainly located inside the e-bike’s motor housing.
• In some e-bike models, controllers are located inside the down tube or the seat tube, while many are placed inside the battery compartment. For more information about the controller and its exact location, you must read the e-bike manufacturer manual.
• Unplug and then plug all the wires. As a precaution, take pictures of them beforehand so that you know which wire is to be mounted in which port.
• Before you plug all the wires into their respective ports, check that they are all clear from the inside and that there is no debris.
• Please check carefully for a loose wire connection between the battery and the controller. In my case, this turned out to be the issue; one of the wires was not appropriately mounted with the battery, resulting in my screen flickering.

PLEASE NOTE:

• Trace every connector from the handlebar to the controller and the battery and check whether it is properly mounted.
• Try re-inserting the battery and ensure it is appropriately mounted if it is removable.
• Check that your brake levers should not be pressed at the time when powering on the e-bike.
• There may be a chance of losing your battery connection or a state of being at a low charge.
• The controller isn’t waterproof and should be protected from water.

Some common e-bike diagnoses:

This is a machine, and mechanical electrical appliances can have a number of problems, so it’s possible that- your battery may be working correctly. Your white LED screen may also be powered on, and you have checked all the settings, but the bike is STILL NOT MOVING! Frustrating, I KNOW-

READ THIS & TRY-

• The role of brake inhibitors prevents the motor from engaging when the rider applies the brake to stop.
• If your brakes are half-pressed for any reason, the power motor will not work, and that was the case with mine. My brake wires were old for a long time, and they were loose thus the sensors were not working properly.
• After that, I replaced them and installed new wires, and then my e-bike motors were able to work.
• So, Always try to make sure that the brake inhibitor wires are appropriately connected.

I CAN’T LEAVE YOU WITHOUT MY OWN TIPS & TRICKS-

There are a few times when you may encounter a situation in which your connector gets some water inside it- been there, done that. In this case, you just disconnect both the male and female wires. Give them time to dry properly. Once you are fully assured that they have dried, follow the steps below. You are going to love this.

• I always clean the male and female connectors, making sure that they are properly cleaned.
• Then, I connect them and wrap the place where they join with a piece of black electrical tape.
• The tape is pretty much invisible because all the connector wires are of the same black color.
• I do that with almost all e-bike connectors to add an extra protection layer.

I hope this helped & I was able to solve your problem, if not, leave me a comment & I will try to help you in fixing this issue. Thankyou so much for your trust & time, please remember ebikeleague & come back for any difficulty you face with you electric bike.

WITH LOVE.
