Low-powered OEM rear-drive...

[eddywanderer]

. . . motor/hub gears: Has anyone around here taken a stock Townie 250W hub (or similar kind of thing) apart and noticed whether the planet gears are plastic or metal? Would plastic ones be plenty reliable enough and have a decent lifespan when driven by a low-powered motor like the one I have?

Danke schoen . . .

Gears are almost always a nylon composite. Quieter and cheaper too, If metal were cheaper, I suppose we'd be hearing the motors sing louder.
.
On bafang motors, which is probably used on a factory Townie, the gears are readily available and not too hard to replace. In fact, on my first 250W motor on a Bafang SWXH model, I bought a set of gears because I thought a 250 would shred. Nope, not unless your drive like the Beach Boys with your pressure plates burning, etc,

In which case, maybe keeping a spare set around would be at least of psychological benefit. ;-) Thanks.

BTW, anyone who can drift through corners while laying rubber on this kind of bike must be a magician. It's got all the blinding horsepower of a cordless drill.
