Planetary gears

Post by johnuk37 »

Hi I hope someone may be able to help.
I have an oxygen s cross MTB mk 2 bike.
I need to buy some new planetary gears for the motor as they are getting worn but have searched on the internet and can't seem to locate any.
All the ones I can find have straight grooves but the grooves on mine are set at an angle and must be hard to source.
Hope someone can help.
Thank you.
John.

Is it a Bafang/6fun hub ?
Single gear or two stage reduction gear ?
How many teeth and gear dimensions ?
A pic would be helpful.

Helical gears aren't common in hub motors unless aikema hubs.
