@younata@pete@meganL@AngelaAntunovic@ascentale power = torque * rpm, so it's a question of how the motor delivers that power, high torque vs high rpm. I've had a bbs02 on an xtracycle edgerunner for a decade, and gone through chains no faster than one should expect for rainy miles vs lube schedule, but I'm geared lower, ~100rpm climbing. Bosch torque-activated drive ads about one extra person standing on the pedal, if you're mashing hard enough to activate, it's 2x tension on the chain.
