Befang 8fun motor from woosh krieger

[Ebiker+]

I need some help from those in the know. I have a woosh krieger ebike that i got when i had epilepsy so could not drive for a year.
Used bike a lot to get around but burnt first motor out then second on the spinndle broke inside motor
And when took it apart the spinndle was so weak a material it had shattered
Can only find info saying its a befang 8fun motor.
I am looking for something better just to get 20mph out of it as 15mph i can peddle that backwards, and as i have a motorbike licence and can now drive again i am trying to find a better motor to fix this bike. Found Andy from woosh not overly helpful and could only tell me nothing else would fit.
Its a mid drive, ive seen the befanghd which sounds like it may fit but not found price very good at over £600
Thank you in advance for any help

The bifang mid drives can all hit 20 mph if derestricted, and you can get 15 mph on your own. Even the BBS 01 can do this.

I know i played with control box on kmh and it put mph up to 20mph but thats what caused my motor spinndle to break as bbs01 are not strong enough

...and the rest with the BBS02 D8ve...easy 30mph with a 38t front chainring here.

The BBS02B 48V 750W can be had for a shade under £400 (UK sourced), but they are illegal (bring on the power-police)

My bbs01 hasn't broken that way but I did fry the controller, now done over 2100 miles and the motor is ok. It gets some abuse at times in all conditions and is good for 24mph with 42/12.

According to the Woosh web site, the Krieger uses the TCM motor. I don't know if this motor is interchangeable with Bafang BBS motors. So perhaps as Andy has told the OP nothing else will fit. Sounds like one for Trex to answer.

Im ripping everything out so im not trying to fit into items already on bike except the whole through the frame only the parts that are interchangable will be used.
I have to do this as dont trust the crap that is being used this is why im asking for help to solve

Just found this but it maybe biased towards woosh bike

Just to note re. the above picture; two slightly longer bolts are required and it IS possible to fit the lock ring with (standard 68-73mm) BBSxx motors on 73mm bottom brackets.
That said, it is likely specific/special tools may be required to do so and to ensure correct torque has been applied with a torque wrench.
If the lock ring is not being fitted, it's important to ensure torque of the main securing ring is 50-60Nm and to check it periodically during the first few hundred miles.
Bafang specific tools pictured below. (Fit half inch drive).

Looking at the way the downtunbe meets the bottom bracket on the current Woosh Krieger, it looks unlikely that a BBSxx will fit as well as the TDM motor. The frame looks designed to allow the (smaller) TDM motor to fit internally within the frame and this compromises it's ability to accept a BBSxx fitted to the exterior/underside as a replacement (it appears it would hang very low if it did fit).
Happy to be educated by anyone with access to better images or that has done the swap...
