If the motor on your electric bicycle makes a clicking sound as you slow down, you must have it checked out as soon as possible so that the problems don't become more severe. Even the highest-quality electric bikes produce a discernible whirring noise while in operation; nonetheless, any noises out of the ordinary or odd should prompt an investigation. This section will investigate the many possible reasons and figure out what we should do about these noises.
If your electric bike produces clicking sounds while decelerating, you may need to adjust the derailleur by loosening the barrel adjuster manually. You may do this if the clicking noises occur when you are decelerating. After you have reduced it, spin the crank and the wheel at the same time while continuing to tighten and loosen the barrel adjuster. Do this until you can move the derailleur without any jerkiness.
If you're riding in a gear that doesn't agree with the bike motor, notably if you installed an eBike kit onto a standard bike, you could hear a clicking sound. This is especially likely to happen if you ride in too high or low gear. You may check whether the issue still occurs after moving gears and listening to the vehicle. If it does, the derailleur is most likely the source of the problem. Your bike's chain can move between various cogs thanks to the derailleur, making it easier for the rider to change gears. When you put your foot on the brakes, you could hear a clicking sound if the derailleur is not aligned correctly.
How to Realign the Derailleur on Your Electric Bike?
In terms of repairs, realigning your derailleur is a relatively straightforward task that you may do. You will want to turn off your electric bicycle and then remove the battery after ensuring that it has been completely drained. When you shift into the seventh gear, you will place the chain on the lowest cog possible. The next step is to raise the frame so that the rear wheel may rotate without restriction. From this vantage point, you can examine the method in which the chain skips cogs, which is the source of the clicking sound.
Make the barrel adjustment a little less tight by using a screwdriver with a Phillips's head. Because the next step requires you to change gears while simultaneously turning the crank, adjusting the barrel until the chain seems to transfer smoothly may necessitate the assistance of another set of hands from a friend or family member.
If your vehicle has an older design with a geared hub, there is a greater chance that a tiny quantity of debris has made its way into the motor. This is particularly true of vehicles with earlier configurations of the geared hub. When you reduce your speed, the unusual sounds become more noticeable since the wind and the spinning wheels can no longer shut them out. If you give your vehicle's engine a thorough inside cleaning, you may be able to dislodge any stones, pieces of metal, or other debris that may have worked their way in while you were driving down the road.
The Proper Way to Clean A Motor With A Geared Hub
A geared hub, much like every other kind of motor, has electric parts inside it. When attempting to clean it with water, use extra caution; you cannot use a hose on an electric bike in the same manner that you would on a conventional bicycle. Make sure that your bicycle is totally turned off, and then remove the batteries and any displays, if there are any. Take a rag that has been slightly dampened for cleaning, and apply it carefully. Degreasing the chains or the motor should be avoided at all costs since it might cause grinding to occur.
There are two rings of magnets known as the stator and the rotor located inside the direct-drive hub motor of your electric bicycle. When the speed of the motor is lowered, the "teeth" on the rotor and stator may sometimes come into contact with one another, which results in a clicking sound. Even though cogging is a problem that occurs in very few contemporary models, sensorless direct drive motors are nevertheless susceptible to experiencing it on occasion.
How to Diagnose and Repair Cogging in a Hub Motor
If the starter settings on your electric bike are not correctly adjusted, mainly when it is under load, you may experience bogging. Adjust the settings on your motorcycle to send more power to the engine when it first starts up. This adjustment to the parameters will probably result in less bogging. If you are still experiencing the problem, you may benefit from upgrading your direct drive to one that has a sensor. Compared to their more modern equivalents, sensor less devices are far more likely to experience cogging.
How to Eliminate Squeaks and Other Sounds Coming from Your Saddle
If the only time your bicycle produces sounds is while you are seated on the saddle, there is a very likely possibility that the noise is from the seat rails or the seat tube. There is a high probability that annoying sounds will emanate from the connection between your seat post and the seat tube of the frame. To our relief, there is a simple solution. Remove your seat post from the frame, clean it, and then clean the interior of the seat tube as well.
Put a little layer of oil over the inside of the seat post collar of an aluminum or steel frame that you are riding, and then slot the seat post back in, being sure to torque it to whatever the manufacturer suggests. If you are riding that frame, you should be good to go. You should follow the same procedure with carbon grip paste if your frame is carbon. When this is done, the majority of seat creaks are eliminated.
If this does not make a difference, the problem may lie with your seat rails. Remove your saddle; take care to make a mental record of the location it was in before being removed, and then clean and gently lubricate the rails and the clamp. When you weigh the saddle, make sure there is no strange flexing or play in it and that both bolts on the clamp have the appropriate amount of tension applied to them. If you maintain the rails and the seat tube, you should be able to get rid of the majority of the creaks that only occur while you are sitting.
