The time has come to retire my Bafang BPM code 12 Rear Motor (Sensorless only)
This is a geared rated 350-750w rated rear motor.
Its laced in a double walled 700c wheel with DT Swiss 12 guage spokes I believe. The rim has seen better days though and from my last bit crash it has a flat spot I cannot get out.
The motor has been through alot including a winter in the UK. I have put roughly 5000 miles on the little beast.
I've over volted it and put it through its paces.
The rear motor is 250 rpm @ 36v nominal. I've predominantly ran it at 44v 23amp most of its life. However I have pushed it to 66v 30amp. The windings are perfect if a little mucky.
Its had its bearings replaced with some decent industrial UK brought ones. There very free running. Please see the below thread for pictures.

All gears are intact and clutch works but its not silent. Sometimes there's some graunching. I currently use this on my bike and it works exactly as it should. But by no means is it perfect.
I AM SELLING IT AS SPARES OR REPAIR.
The Price Reflects this.
It would make an great off road build where silence isn't a problem or if you want to test it to destruction.
Heres a video of me on my commute @ 44v

If anyone has the same motor it would make a good spares as the gears and clutch and bearings are still worth what I'm selling it for.
I'm asking £50 laced and P&P
£45 Motor only and P&P (postage will be cheaper though)
I would swap for a perfectly working Rear Bafang 250w motor Or other rear geared motor.
Let me know if this is of any use / interest to you.
Based in Birmingham for collection.
