Model of Suzhou Bafang Motor? Need to order spare gear wheel

[niklas]

I planned to order one of these replacement gear wheel for my bike.

In order to pick the right gear wheel I need to know the motor model:

• BPM
• BPM2
• SWXH
• SWXK
• SWXK2

Can anyone tell by the pictures what the model might be, or know where to look for the model of the motor?

I found one sticker, but unfortunately without model number:

I believe you can eliminate the BPMs..it looks very familar to mine, from 24v Clean Republic front driver, it is one of the SWX's, not sure which one.

Thanks, only two more to eliminate...

It's a Higlands golden pigeon ebike with premounted motor on rear wheel. More ideas?

Thanks docnjoj! Is this the ecrazyman keywin?

I got some a while back including steel ones.

Seems interesting with steel ones. Are there any downsides with those? My nylon gear wheels lasted for less than a year, would be nice to avoid replacing them every year.

All I saw was 1 gear. So count the teeht and see if they are the same count.

Also the metal gears are much noiser. Have one in a BMC and they are much louder.

Mine have are 36 tooth gear wheels, but the replacement gear wheels at greenbikekit explicitly says 24 tooth.

Also the metal gears are much noiser. Have one in a BMC and they are much louder.

Ok, so how long would you guess that they last, based on the fact that my nylons last less than a year?

Thanks a lot for the info, do you know if those 12mm gear wheels are compatible with motors originally made to use 10mm gear wheels?
