I haven't proposed any specific gear model. I have yet to find one "off the shelf".
I did check with local gear shops moths ago. They want $500 to analyze the gear.
And even more money to fabricate it from scratch.
Shame. That lil motor packs a lot a power.
Would be nice to have gears that can handle it.

A stainless set of 3 gears could wear out the pinion and sun gear quickly, possibly. This could be something to think about...
it would be interesting to see if the new composite gears for the BMC are the same size. maybe there is some way to convince bafang to manufacture with the composite gears from the start.

If nylon can make it as far as it has been described here, then non anodized 6011-t6 can handle it with no problem. It would wear over time because it is softer than steel, but still last a while.
