Yaban S11e E-Bike 11-speed electric bike chain

The chain has markings on both sides, so it's complicated to know which way to mount it. Moreover, on the box, it is advised for safety reasons to read the manual, but there is no manual either in the box or on the company's website! The chain seems to be of good quality and comes with a quick link and a pin to be mounted with a chain tool, like on Shimano; it is actually easier to mount than Shimano because it is possible to remove the small pin that was used to center the axle by unscrewing it. The problem is that the axle that remains in the link is hollow, which may not last too long. I may not have mounted it correctly, but I could only have known that by reading the manual, which I still haven't found! (Translated review)

This special chain for e-bikes does not meet my expectations! Although it is compatible with SRAM, it replaces my original KMC very poorly. This chain clicks continuously, it is not flexible enough for the 15-tooth motor output sprocket. (Translated review)

Superb quality and easy assembly. Quite light but very durable. Smoothness and precision. I recommend. (Translated review)
