Keren supply professional and honest service.

An electric bicycle is a reliable way of getting around, whether you need to get to work or want to explore the great outdoors on two wheels. However, like a regular bicycle, an e-bike needs occasional maintenance and repairs.

Thankfully, repairing your electric bike isn&#;t as expensive as you might think. Even if you need to call in the professionals, e-bike repairs are much cheaper than maintenance on a car, truck, or motorcycle.

Plus, that&#;s assuming you need to take your e-bike into the shop in the first place! A lot of the time, you can check and fix many common e-bike problems on your own. This electric bike troubleshooting guide has you covered. Read on to learn about the most common electric bike issues and general tips for checking your e-bike&#;s functionality.

Common E-Bike Problems and How to Fix Them

Although electric bikes are sophisticated and reliable machines, every tool needs TLC from time to time.

Fortunately, most of the common issues you&#;re likely to encounter can be resolved swiftly and at no cost. From a controller malfunction to your battery not charging, some common problems happen in e-bikes regardless of the brand, type, or model. Here are some issues you may experience as an e-bike owner, with a quick DIY troubleshooting guide, so you know how to address each one.

E-Bike Controller Not Working

Your e-bike controller connects the bike&#;s various electrical components, like the e-bike motor, throttle, pedal assist, battery, sensors, and LCD (if it has one). It&#;s basically like a small computer and coordinates the bike&#;s overall function. 

Think about it like the brain of your e-bike. If it isn&#;t working, the e-bike&#;s brain isn&#;t working.

Various issues can impact the controller, like faulty wiring and other connections coming loose, the on/off switch not working, or the controller&#;s fuse or circuit breaker not functioning properly.

Whatever the issue, remember to stay calm. It&#;s likely a small and simple problem that can be resolved within a few minutes. When in doubt, try restarting your e-bike, just like you would restart a malfucntioning iPhone. If that doesn&#;t work, we explain some of the most common e-bike troubleshooting solutions below.

How to Check Your Controller

Take these steps to see if the e-bike controller is the issue: 

  1. If the controller isn&#;t working, start by checking the power switch. Switch it on if it&#;s not in the &#;on&#; position.
  2. Check for any incorrectly connected, disconnected, or loose wiring. If you see improperly connected wires, you can reconnect them yourself. Most bike wiring is color-coded (so a blue wire matches a blue port or outlet).
  3. If the controller has a circuit breaker, reset the breaker. You can do this by pushing on it. Be aware that the circuit breaker is meant to protect the system, so if it keeps switching out, there might be a bigger problem requiring the entire system&#;s replacement.
  4. If the e-bike has a fuse, check to make sure it&#;s not burned out. You can remove the fuse and hold it to the light. You should be able to see if it&#;s burned out. If it is, you&#;ll need to replace it.

Any issues that involve a feature being broken, such as the fuse or a system malfunction, are highly unlikely if your bike is newer. These issues typically occur after you&#;ve ridden for many miles on your bike. 

However, if you are encountering broken features on a new bike, you may need to seek professional assistance.

E-Bike Throttle Not Working

Some e-bikes have throttle assist and a pedal assist system (PAS). Throttle assist engages the motor even when you aren&#;t pedaling, powering the bike forward independently. 

The throttle is what activates this mechanism. If there&#;s something wrong with the throttle, the throttle assist function won&#;t work.

If you&#;re riding on a Velotric bike, you&#;ll have a throttle and a PAS at your disposal. Thankfully, this doesn&#;t require double the maintenance or work compared to bikes with just one or the other. 

That being said, having a PAS and a throttle can make it more difficult to detect where the issue lies. Certain problems can arise that involve both parts of the bike, and it&#;s important to test both to find out which is malfunctioning. 

In most cases, the throttle malfunctions because it&#;s been overused. If you push on the throttle for too long, it can get stuck in position and fail to revert. As a result, the throttle can become damaged or loose over time. You may notice that throttle assist simply cuts out while cycling.

How to Check the Throttle

Follow these steps to troubleshoot the throttle:

  1. Check the throttle&#;s position (by the bike&#;s handlebars). A malfunctioning throttle will generally get stuck in the rearmost position instead of popping back into place.
  2. Manually pull the throttle back into place. Under power failure, test the throttle by pushing it into the rearmost position and seeing if it pops back into place right away or lags.
  3. If the throttle doesn&#;t pop back into place or does so slowly, you&#;ll need to replace it.

Again, throttle replacement should only be needed if your bike has seen a lot of wear and tear. If you do need a replacement, rest easy knowing that it shouldn&#;t be prohibitively expensive. 

E-Bike Pedal Assist Not Working

The PAS helps power the bike forward while you&#;re pedaling. Most bikes have different levels of pedal assist, providing different levels of support. 

For example, Velotric&#;s Velotric Nomad 1 and Velotric Discover 1 have five levels of pedal assist. If the pedal assist system isn&#;t working, you&#;ve basically got a regular bike.

We love standard bikes, but we chose an electric bike for a reason. We want the additional features and benefits e-bikes have to offer! Thankfully, there are easy fixes for PAS issues, too.

The PAS may malfunction because of power cutoffs or inconsistencies in the power supply. Depending on the type of system, connectivity issues with the bike&#;s pedal, sprockets, chain paddles, or wheels might be to blame for the intermittent power. An issue with the magnet ring and sensor on the front sprocket can also be the cause.

How to Check Your PAS

Here&#;s how to figure out what&#;s causing your PAS problems:

  1. Check for any loose parts or connections if you&#;ve recently adjusted the mechanical components on your bike, like the sprockets or chain paddles.
  2. Look at the magnet ring on the bike&#;s front sprocket. It should be placed so that the magnet and sensor are aligned.
  3. If the magnet ring has been jostled out of place or is dirty, it might need adjusting. You can adjust the magnet using a flathead screwdriver, applying gentle pressure to move it closer to the sensor.
  4. If the above steps don&#;t work, you should visit a bike shop for professional help. They can identify, remove, and replace faulty parts.

E-Bike Battery Not Charging

If the e-bike controller is comparable to the vehicle&#;s brain, you could say the battery is like the e-bike&#;s heart. It keeps the bike&#;s motor going, allowing the PAS and throttle assist to work. 

If the battery isn&#;t charging, you won&#;t be able to use your bike&#;s full functionality. It may not start or keep powering off, for example.

The e-bike battery can fail to charge for various reasons. A fuse might be blown, the battery might be depleted from too-frequent charging, or the battery pack may simply be old or defective. 

Another possibility is that the battery&#;s pins, which serve as the connector to the charging port, aren&#;t properly placed, so the electric circuit isn&#;t completed when the battery&#;s plugged in &#; meaning it doesn&#;t charge.

How to Check Your Battery

Try these steps for troubleshooting your e-bike&#;s electric battery management system:

  1. Start with the basics and check the battery charger. Plug it into the wall and see if any indicator lights turn on. For example, if the indicator light doesn&#;t turn on when the charger is plugged into the wall, you may have a defective charger.
  2. Sometimes, it may not be the charger but the charger port that&#;s the issue. To check this, unplug the charger and insert the battery into the charger port. Check the indicator light. If it doesn&#;t turn on, the charger port&#;s wiring might be faulty and may need replacing.
  3. Next, check the battery&#;s voltage. If the LED lights on the e-bike and its control panel don&#;t light up, the battery may not be charged. You can use a voltmeter to check the battery&#;s voltage. We go into more detail about how to do that below.
  4. If the battery charges but fails during use, it might have been overloaded (which also poses a risk of overheating). You can address this by pedaling harder while cycling or lowering your use of pedal assist. Overloaded batteries may also result from a low-quality battery or premature aging (a good battery should have a lifespan of three to five years). If the e-bike battery continuously gets overloaded despite a decreased use of PAS, it may need replacing.
  5. Look at the battery&#;s pins. These allow the battery to complete the electric circuit when plugged into the charger. This is how the battery gets power. If the prongs are misaligned, the circuit can&#;t be completed, and charging won&#;t occur. You can check if pins are misaligned and realign them using a wrench.

It&#;s also important to have a backup battery pack on-hand. Sometimes, we forget to charge our batteries before a big ride. Other times, our batteries just aren&#;t working. While we can troubleshoot our battery issues eventually, having a backup battery charged and ready to go means you can ride now and worry about the rest later.

E-Bike Brakes Not Working

Your e-bike brakes are essential for safe cycling, ensuring you can stop when necessary. 

There are different types of e-bike brake systems (we talk about the various types of brakes). The reasons for e-bike brake malfunctions can vary according to the brake system type, so it&#;s important to know what brakes you have.

Regardless of the type of brake system, e-bike brakes can get worn out with time. Factors like external dirt, debris entering the brake system, and poor brake alignment can worsen the problem. If the brake pads or rotors become damaged or worn down, braking may not be as smooth or sharp.

How to Check Your Brakes

To troubleshoot your e-bike brakes, follow these steps:

  1. If the brakes suddenly stop working, inspect the brake discs for debris like mud or dirt. Clean off any grime to see if the issue improves.
  2. Look at the brake pads and rotors, scanning for signs of wear and tear, like scuffs and cracks. They may need replacing.
  3. Check the brake lever or cable adjuster on the e-bike. If it&#;s loose, it may need tightening to make the brake more sensitive.
  4. A related issue might be the brake motor inhibitor. If the bike has been dropped or jostled, the motor inhibitor switch may get stuck in the &#;on&#; position. Check if the brake levers are jammed and try to move them. If you can&#;t, you may need to replace them.
  5. If you aren&#;t sure what the issue is, take the e-bike to a professional bike mechanic. They can determine whether you need to replace parts or the entire brake system.

Other E-Bike Tips

The more you know about your e-bike, the better you can care for it &#; and the longer it will last. 

Check your e-bike functionality using the below steps.

How to Check E-Bike Battery Voltage

The e-bike&#;s battery voltage determines its power. If the battery isn&#;t meeting its full voltage capacity, it might be old and needs replacing &#; or, if you&#;re dealing with a new e-bike, the battery might be defective. 

It&#;s good to identify defects immediately while your bike is still under warranty.

You can check an e-bike battery&#;s voltage with the help of a voltmeter or multimeter. Start by attaching the prongs of the device to the battery, aligning the positive and negative sides accordingly. 

Alternatively, you can secure the voltmeter to the battery&#;s charger connector.

The voltmeter will show you if the battery drains faster than it should. If it drains too fast, determine when the battery was last charged. 

If the battery pack hasn&#;t been charged for six months or less, it may need a top-up. If the battery pack hasn&#;t been charged in over six months, it might be defective.

How to Test the E-bike Battery Charger

Sometimes, it&#;s not the battery that&#;s the issue but the battery charger. This is an easy issue to troubleshoot. 

You don&#;t even need any tools to get it done. Plug the battery charger into an electric outlet. Ideally, the indicator light will come on and stay on steadily.

However, if there is an issue, the indicator light may not come on or blinks intermittently. This indicates the charger isn&#;t getting power from the socket as it should.

You can use a voltmeter to double-check. The voltmeter should give a reading a little bit higher than the designated voltage of the charger. If the charger&#;s reading is below voltage, you&#;ll need to replace the charger.

How To Diagnose E-Bike Wiring Issues

The various components of your e-bike &#; like the controller, motor, and battery &#; are connected with wiring systems. These wires transfer power between these key parts, so if they&#;re loose, frayed, disconnected, or otherwise faulty, the e-bike might experience mechanical issues.

Consult your e-bike user manual to identify and locate the various wiring systems. For example, the e-bike controller (the &#;brain&#; of the bike) is one wired component. 

Check for loose or incorrectly placed wires. This is simply because the wires are color-coded: A blue wire fits a blue port, a red wire fits a red port, and so on.

In some cases, loose wiring might be the issue. In others, the wire might be damaged. You can use a voltage tester to check a wire&#;s integrity, moving it along the length of the wire to determine where voltage is diminished &#; an indication of damage.

Depending on the issue, you might need to replace the wire. This is a job best left to a professional repair shop. They&#;ll know what parts to replace and can make sure they&#;re properly installed.

Top 5 Hunting Electric Bike Problems [And What to Do ...

You could sit around dreaming of a maintenance-free world. You could think about how nice it would be if vehicles didn't break down and even build a cushy little bubble where maintenance isn't a part of things.

If something breaks, just replace it. 

Or, you can accept that things will break from time to time. Considering you're the type of person who enjoys pulling yourself by your boot-straps, rolling up your sleeves, and getting to work, we know you're more accustomed to option two. 

The simple fact is that your hunting eBike is going to experience failure at one point or another. However, unless you have the money to replace it or the time to send it off to the repair shop, there are some things you can easily do yourself.

That's why we want to take a minute to talk you through some of the most common problems and what to do when you encounter them. 

Thankfully, eBikes are pretty simple, so you'll be ready to roll with the punches in no time. 

Following are the top five electric hunting bike problems:

1. Motor noise 

Motor noise is about the worst of the issues you're bound to encounter.

As you're riding along, you may hear a whirring noise whenever the motor is engaged. Just like on your hunting rig, this is a sine of worn-out bearings. 

Bearings are almost a sacrificial part. While they do feature rolling elements to reduce friction, they will still wear down over time. 

On an eBike that doesn't see adverse conditions, the bearings that could last the lifetime of a motor, mountain, and hunting eBikes are often a different story. Some bearings give up after just around a thousand miles or so. 

There's no need to panic about worn-out bearings, and you can likely have them replaced through the warranty. If the warranty is out, you can opt to replace them yourself to save money. 

You just need to make sure you follow the exact procedure as laid out by the manufacturer.

2. Water in the System

The next most serious issue you can run into is water in the system, including your eBike's battery. 

Some models may warn you if there's water in the battery or other electrical components, and you should act accordingly if you see them. Others don't.

eBikes are tough pieces of gear, but they aren't invincible, and they certainly aren't intended to be submerged in water. 

Getting water inside can be highly dangerous to the electrical components, and you want to keep it out. 

If the bike is submerged in water or known water is inside key components, you will want to remove the battery and store the eBike in a dry area with low humidity for a day or so to allow the moisture to evaporate. 

If you still get any warnings, you may need to use the warranty or replace damaged components.

3. Lack of Power   

What if your eBike checks out and there are no obvious issues, but when you go to start moving, there's no power? 

The motor is trying to provide motion, but it just doesn't have enough oomph. Well, it could have something to do with the speed sensor. 

The speed sensor lets the system know how fast the eBike is going, necessary for motor input.

Without this information, the motor won't know if power is necessary, and power levels can be all off. A tell-tale sign that it is the issue is a lack of speed readings on your display. 

If you are experiencing this issue, you should first make sure there is no debris on the spoke magnet to throw off the reading. 

Next, make sure the spoke magnet is in the correct position and that the spoke is not loose. 

If you're still experiencing issues, locate the wiring and see that it's not damaged or disconnected. Unfortunately, it is common for rough terrain to wreak havoc on this component.

4. Dead battery after charge 

Nothing will stop you in your tracks faster than a dead battery. It is the life force of your eBike, after all. 

It's not something that'll exactly send you into a panic, especially not if you have a spare fully charged and ready to go. 

If your battery is dead after it's been on the charger all night, there are a few things you need to inspect. 

First and foremost, make sure the charger is plugged in and working. If the charger checks out, it's important to think about the area the battery is sitting in while it charges. 

It's not likely to be subjected to extreme heat, which impacts charging, but you might have made the mistake of keeping it somewhere cold. 

If that's true, relocate it to an area where climate conditions are more acceptable and charge again. If the issue persists, it may be time to replace the battery.

5. Dead display

The last issue we will look at is probably the least concerning, which is a dead display. 

This won't keep you from taking the eBike hunting as you normally would. It just means you can't monitor what's going on. You should still get it squared away ASAP because there's a lot of important data you need to keep in mind. 

The solution might be as simple as a loose connection. Some displays use their flat battery, though, and you will need to replace it if it's dead.

If neither of these issues is present, you will want to visit a professional shop that can perform the necessary repair or put your warranty to work. 

Now for the bad news. These are just some of the most common issues across all eBikes. They don't consider that your particular model may have a few quirks that are worth being aware of. 

Some bikes might have issues with handlebars coming loose, others with chains popping off. It all depends on what you have to work with. 

The point is to do the homework, find out what issues others commonly run into, and learn how to deal with them accordingly. That might sound like a lot of homework, but eBikes are nearly as simple as any other bicycle.

They don't rival the complexities of other systems you've already mastered, and you should have no trouble keeping yours in check.
