An Electric bicycle is an electro-mechanical device, which simply means that it works with an electric-assisted system and has a mechanical side to it as well. Now, often the electric-assisted side will show problems here and there which may be frustrating, especially if you have never had to solve any electrical issues before but addressing the issue and trying to fix it yourself will not only enhance your knowledge on the matter but also save you tons of money which you would have otherwise spent at the repair shop. We aren’t saying that all problems can be fixed within your backyard but some common problems, which we will cover today, are totally fixable. So we hope you are ready for some trouble-shooting.
Motor Will Not Run or Runs Slowly
The first and most common problem with an Electric bicycle is that the engine will simply not run. The first thing to check is how long ago was the battery pack charged. In most cases, an engine will not start if the battery is dead because the engine gets its power from the battery. Charge the battery pack for at least 8 hours and try again. If the motor still doesn’t run then try the following:
Check the fuse and the circuit breaker
A blown-up fuse may be the culprit or if your bike has a circuit breaker then try flipping the switch to see if it works.
Check for burnt or loose wires
As the electric-controller board is fixed with tons of wires, having a loose or burnt wire may disconnect all electrical communication and cause the engine not to respond.
If the brake lever switch wears out in the on position then it will cause the speed controller to remain turned off. To test this, simply disconnect the brake lever switch and try running the Electric bicycle.
Damaged battery charger or faulty port
You may have kept the battery on charge for 8 hours and think that the battery is fully charged but if the charger is damaged or the charger port is faulty then the battery will not charge and remain useless to the engine. Make sure both the charger and the port are working well to determine the health of the battery.
Overheated motor coils
Look for any melted wires attached to the motor. If you smell a burnt smell then chances are that the coils on the motor have been burnt due to overheating. A motor with damaged coils must be replaced immediately.
Batteries Lose Charge Too Quickly
This may be because of age. Worn out batteries will not have enough power and lose the ability to hold its charge for long. But if the batteries are fairly new then try using them on another bike to see if the problem lies with the batteries or the bike itself.
Flat tires-Electric bicycle
This problem can be avoided in the first place by careful riding and accurate tire installation. However, it may not always be possible to watch where you are going and hazards such as thorns, glass or other sharp objects may cause the tire to puncture. But other than the unavoidable reasons, improper installation may cause flat tires. It is also important to keep the tires as full of air so they can hold the weight on the bike.
The first thing you must do is check the brake pads and make sure they are not damaged. Replace them if they seem worn out. You may even try to tighten the brake cable adjuster so the brakes respond better. The braking system needs a lot of maintaining so always keep the brake pivot points lightly lubricated and keep the rims and discs clean so they stay straight and last long.
Motor runs non-stop
E-bicycle has speed controllers and defective speed controllers may cause the motor to run continuously. If the transistors on the speed controller burn out then the power remains on which makes the motor run at full speed continuously. Speed controllers can be replaced but you will have to consult the customer care for the company that manufactured the bike or seek professional help from repair shops. However, the problem may also be caused by a faulty throttle or a short circuit in the throttle cable.
If you do not have a spare key then you may have to replace the key switch with a new one if you manage to find one. It won’t cost much. You can also have a new key made by a locksmith for which you will have to purchase a key blank.
Lithium batteries are flammable and must be handled with care and caution. Avoid overcharging the batteries and never allow them to get punctured. Also, make sure your charger and charging port is compatible with the batteries and working well.
Most e-bikes can withstand harsh weather and some can be ridden on snow and in pouring weather but avoiding it as much as possible will help prolong your bikes life. E-bikes have are electric-assisted so they have some delicate wiring and circuits which need to be handled with caution so try avoiding anything that may cause damage to any parts on the bike.
You can prevent any serious issues beforehand by teaching yourself the basic mechanism of an E-bike and how to respond when the common problems arise. By learning how to fix things yourself, you can avoid the hassle of taking the bike to a repair shop which will no doubt cost you extra money. Maintaining the device and keeping a check on little details such as battery life, flat tires and smooth working brakes will save you a lot of trouble and also make your rides make your rides.
