Niche motors reliability

Ten motors, one honest pattern: the Pinion MGU's gearbox has been near-faultless with the gripes living in its FIT software ecosystem; the Flyon-era TQ HPR120S fails at the wiring loom, not the motor; the Polini's story is serviceability itself; and six smaller motors simply lack the owner data to judge at all.

Where the data is thin this page says so: the absence of failure reports in 200-odd posts is not a reliability record.
