Causes of jumping teeth on electric mountain bikes

Causes of jumping teeth on electric mountain bikes

When you are riding, have you noticed that the bike chain has clicked and clicked on the gear shift several times? It turns out that the bike chain has skipped teeth. At first, you will think that the chain has exceeded its service life, but in fact the chain has been stretched and caused the skipped teeth. , If the chain has not been maintained in the past, and occasionally a little oil is applied, the sound of the chain will appear. In fact, electric bicycles need regular maintenance and maintenance, especially the wearable transmission part, and the chain is of course one of them.

It is also possible that it has nothing to do with the bike  chain, but has to do with the chainring and flywheel. Once these two items exceed their service life, sharpened gears will cause tooth skipping, but this reason has not yet been verified.

The last phenomenon is also possible, it is too loose the transmission line, or the gear skipping caused by the shift of the transmission caused by too tight, the normal reason must be a little more cause of the chain, but these two situations cannot be ruled out.

But no matter what the reason is, we have to check. First, check that the chainring or flywheel tooth or chain has the same, two or three types of wear and serious wear. Although the chain is in place, it can’t hang under increased force. Jump chain appears. In this case, it is recommended to replace the more severely worn parts.

Then look at the bike chain to see if a certain section of it is not compliant, whether the chain is not in place, and the bike  chain jumps after turning to a certain position. You can use this link to smooth the chain. Generally, this situation is caused by the chain.

Secondly, under the condition of increasing force, the rear edge of the chainring or flywheel tooth will press against the new bike chain, so that the chain will not fall in place, and the chain will jump after turning to a certain position, so as to better sharpen the rear edge of the tooth.

Finally, look at the positioning of the rear derailleur. When the force is applied, the chainring or the tooth tip of the flywheel is against the bike chain, so that the chain does not fall in place, and the chain jumps after turning to a certain position. You can use the method of adjusting the rear dial. This situation is more common. It is generally a problem with the transmission cable. If the fine-tuning screw is adjusted and the teeth are skipped, it is recommended to replace the transmission outer tube and the inner cable.
