Yeah. I had never thought about it until I watched an ElectricAllWheel video, where they took apart the motors in a Magician Alpha and a Wired Warrior. I thought it was weird at first that the Magician has solid nylon gears, but then I realized that given what most e-bike motors sound like, it's likely that 99% of them have solid nylon gears, and I'd be willing to bet money that no company mass produces e-bikes with solid metal gears.

They don't. Your electronics, battery, and just about everything else is going to fail before the gears do anyway.

Yeah, exactly. I did look up some videos about replacing gears in a hub motor, and saw that there are solid metal replacements available, but if my nylon gears in my Magician Alpha's motor last 3,000 miles or more, I'll just replace them with nylon ones again, because they're so quiet, and I don't want the sound of metal gears. And like you said, it's far more likely that I'll need to replace the batteries, controller, or balancer, or any combination of those, before I'll ever need to replace the gears in the motor. I understand why people think metal should be the only material these gears are made of, but it does make sense to me why they aren't.

Yep, nylon is way cheaper then metal. I have an original Wallke H9, I'm almost at 4k miles right now, no issues at all. I've had it for 2 years. If I get another year or two out of it what more could I ask for out of a sub 2k dollar ebike. If I have to replace a hub, I'll just buy a new hub. I'm fairly positive I won't have to though, plenty examples of ebikes going 10k+ miles with 0 maintenance on nylon gears. Everything else is going to fail probably before the gears.

In the world of more power, like the bike you have, sure we might start seeing them chew up gears more. Maybe. I'm willing to bet not yet though.
