This is an Ultegra 11s chain after 1000km of wear from a 1500W mid-drive. Used to ride a Tangent back in 2016. T’was shredding till it went *clunk*.

    Yeah I replace my ebike chain every 1200km (every 9 to 12 months) even if it doesn’t look like that and only uses a 500W motor.

      I have a “1500W” mid-drive and it lasts maybe 6 months, if I don’t fuck up and shift under load. I do need to clean it more but… Next ebike is gonna be a belt drive.
