Methods Of Daily Repair And Maintenance Of Electric bike

Whether you're a electric bike commuter, weekend road fanatic or mountain electric bike enthusiast. Learning to maintain and repair your own electric bike is rewarding. These skills will unlock new freedoms, save you money, and potentially someday get you out of trouble on the road. GUNAI has sorted out 23 common bicycle fault repairs and detailed explanations of skills, hoping to be helpful to you.

Maintenance Methods

➡1 Store your batteries properly

The battery is one of the most expensive components in an electric bike. A battery replacement can cost you upwards of $1,000, so it pays to keep it in good shape.

The first is to consider the conditions for storing and charging the electric bike. For example, Shimano recommends a safe temperature range of 0 to 40ºC for charging and -10º to 50ºC for operation. While batteries may operate under extreme conditions, for the life of the battery it is best to keep it at approximately 20ºC. If the electric bike is stored in a cold place during the winter, such as an unheated garage, it is best to remove the battery and bring it indoors.

In terms of storage, the electric bike is electric and water ingress would be a potential problem. Storing your electric bike indoors is the best way to keep your electric bike in tip-top shape. For that matter, any bike, electric or not, should not be stored outside, even covered, as moisture, rain, etc. can cause corrosion and the seals can dry out, which can often damage the bike.

➡2 Clean your electric bike regularly.

This should be necessary, especially if you use your e-bike on a daily basis, or if your e-mountain bike is on the road. The battery and motor are safely sealed, so you don't have to worry about water getting in.

However, when cleaning an electric bicycle, you cannot use a high-pressure water gun to rinse it. Doing so could allow water to seep into the bike, potentially damaging its electronics.

➡3Keep mechanical parts lubricated.

In order for your electric bike to run smoothly, you have to make sure all the mechanics are working properly. By regularly lubricating moving parts such as your chain, you can ensure that the chain doesn't wear down any faster.

Lubrication will help effectively prevent friction plates and rollers. Metal tends to wear out faster when exposed to dirt, so keeping your chain clean is crucial.

Keeping it lubricated will eliminate annoying squeaks and maintain a smooth ride. Additionally, lubricating the chain can save an e-bike 5-10 watts of energy, depending on the brand.

IMPORTANT: When applying lubricant, make sure that no lubricant gets into the wire port.

➡4Check the bolts

Do a quick check to see if there are any loose screws, bolts, nuts or anything else on the bike. If the bolts have too much play, tighten them up a bit and see if you can find the cause of the looseness. Do not overtighten the bolts.

➡5Brake pads

Take a good look at the brake pads on your bike every few weeks to see how they are holding up. It's essential that you have effective brakes or else you could end up in a serious accident. Brake pads can easily and cheaply be replaced whenever necessary.


Repair Methods

➡1 Every time the inner tube is mended, it becomes deflated just after putting it back in

If the hole in the inner tube is on the inside, the pad may be misaligned, causing the tube to be cut by the spokes; if it is on the outside, there may be some small, sharp foreign object in the tire. Carefully feel the inside of the tire with your fingers to find the foreign object and remove it.

➡2 Reinstall the tire, but it cannot fit into the rim normally

Let off the air, twist the tire back and forth, and knead the tire into the correct position with your bare hands. Push the electric bike tire from the outside to the middle and check if there is any inner tube sticking out. Make sure to re-inflate the inner tube when it is fully seated in the outer tire.

➡3 Adjusting the rear derailleur still can't improve the noise and inaccurate shifting

The cassette lock ring may be loose, causing the cassette to vibrate slightly and rattle as it turns. Special tools are required to tighten the lockring fully, but you can use your fingers to tighten it as far as you can, enough for a safe ride home or to the nearest bike shop.

➡4 You installed the left and right pedals backwards

You can remove the electric bike pedals, but you'll probably have to replace the crank; the crank's threads are softer than the pedals' and are more likely to break. Always check the threads before installing the pedals. Usually there will be an "R" or "L" on the axle of the pedal to represent "right" or "left".

➡5 When using certain gear ratios, the pedaling appears to skip gears

There may be something between the electric bike sprocket. If you can see clods of mud, weeds, leaves, twigs, or any foreign objects stuck in the flywheel, dig them out. These things prevent the chain from engaging properly with the cassette. If there is nothing, the sprocket may be worn out. This phenomenon usually indicates that the chain and flywheel need to be replaced.
