How to Fix or Repair Ebike Chain?

Maintenance of Electric Bike

If you use your ebike frequently, the parts will eventually deteriorate. A chain on an electric bicycle will “stretch” after a certain amount of kilometers and has to be changed. 

Proper chain maintenance is even more important for electric bikes because they experience more torque and more damage than ordinary bikes. 

The ideal methods for keeping an e-bike chain in good condition are to keep it clean, lubricate it frequently, use the right chain lubricant, and do routine checks for problems with the chain. 

What is the best way to measure chain wear? 

There are a few fast and simple methods you may use to assess how worn or stretched your chain is.

What is the best way to measure chain wear.

The length of a new chain, from center of pin to middle of pin, should be precisely 12 inches across 12 links. One percent elongation between links is the value that is most frequently agreed upon for a worn chain. However, you should change the chain earlier than this. 

The time to replace a chain would thus be any time after 12.062in (0.5%). Anything longer than 12.125in (1%), however, has likely been worn to death and must be replaced with a new cassette. 

The use of a chain measure equipment to measure the chain is the most advanced and precise method of evaluating ebike chain wear. It is simple to operate. 

What is the reason for chain break? 

The chain of ebike is broken

● Your chain will most frequently become destroyed if it is subjected to excessive stress.

● A chain might become useless even before it totally breaks. A single twisted or bent link might occasionally be enough to cause shifting to become erratic and result in a very unpleasant riding experience.

● Chain slack. Yes, it really exists. Despite being composed of metal; your chain will eventually get longer as it wears down. Chain-rings and cassette will deteriorate as the chain wears, too.

● Despite being the least frequent way of chain breakage, a direct, forceful impact on the chain might nevertheless result in substantial damage.

How to fix e bike chain

1. Select the bike’s lowest front gear 

⮚ Before stepping off, move the bike into the lowest front gear. 

⮚ When the front gear is at its lowest position, the biggest chain-ring will support the chain. 

⮚ Do not stop pedaling. This action might realign the chain on its own. 

2. Dismount the bike and raise the back tire 

If Step 1 didn’t work, get off the bike and physically spin the pedals while lifting the rear tire.

3. Forward-pushing the rear derailleur to relieve tension 

⮚ If Step 2 is inadequate, move the rear derailleur forward to release the chain tension. ⮚ Lift the chain to reposition it on the chain ring. 

⮚ To adjust the chain, lift the back wheel and crank the pedals with your hand. 

⮚ Due of how greasy bike chains are, your hands will become filthy. If latex gloves are not easily 

available, consider using a leaf or twig as a substitute. 

4. Slipped Chains 

⮚ Your chain can be too long if it slips regularly. 

⮚ Put the chain on the outside chain guide of the chain breaker. 

⮚ Turn the handle of the chain breaker to partly release the chain pin.

⮚ Use as much effort as you can without fearing that you’ll break something if the pin looks stuck.

5. Remove the chain breaker 

The chain breaker may be taken out by drawing the driving pin back. Separating the chain is necessary.

6. To delete a link, repeat steps 4-5 

Then repeat steps 4-5 to delete the link: Two halves, one broad and one narrow, make comprise a single link. The chain cannot be put back together until both are removed. 

7. Re-fed via the correct pulleys 

⮚ If the chain comes off the rear derailleur, it must be refed through the proper pulleys. ⮚ The guide pulley, which is the higher of the two pulleys, should receive the chain. ⮚ Thread the chain through the derailleur cage between the tension and guide pulleys. ⮚ Thread the chain through the tab. 

⮚ After that, feed the chain through the tension pulley. 

8. Line up the chain’s exposed ends 

⮚ To make a new chain, line up the chain’s free ends. Put the chain on the chain breaker’s outer guide with the pin facing the driving pin. 

⮚ Turn the driving pin once it is evenly spread apart from the face plates like all the other links.

9. Move the newly-reattached link around. 

⮚ Wiggle the link after reattaching it. 

⮚ Place the chain on the internal guide of the chain breaker and turn the driving pin just a little. Verify that the appropriate looseness is being achieved as you proceed. 

⮚ As previously, don’t take the pin entirely out. 

How to select Bike chain size? Which is the best size

Many mountain bikes have 10, 11, or 12 speeds, and a chain will be plainly marked as such when purchased. Simply count the number of gears on the back cassette and multiply it by the number of chain-rings up front to determine how many gears, or “speeds,” your bike has, then choose the equivalent chain. 

Bike chain tools 

1. Chain Tool 

You must have a chain tool in your riding equipment. Make sure you have a chain breaker with you on every ride, regardless of whether your multi-tool includes one or you like to carry a separate one for convenience. Using a chain tool, you can easily take out and replace any damaged or broken links. 

2. Third Hand Tool 

A simple bent piece of metal is used as a third hand tool to clip the chain’s two free ends together and keep them there while you rebuild the chain. You can always construct your own chain tools by cutting and bending an old bicycle spoke to fit. Some chain tools come with them. 

When both of your hands are engaged attempting to operate the chain tool and keep all those tiny components in place as you reconnect them, this compact tool is a big aid. 

3. Spare Master Links 

A chain’s two unconnected ends are joined by the so-called master link. If you need to take off or replace a chain from your bike, you may quickly open and shut this connection. If any other links are damaged and need to be removed, a spare master link is a wonderful backup chain link. 

A master link can fix any damaged link and get you back on the road, therefore you should always have at least one spare in your repair kit.
