Ok, the motors I make are for my own use and are not accurately made (I use simple tools), but the
potential is definately there. This is my triple stator base on a bicycle axle (meant for chain
drive to rear wheel or mid-drive):

I really like the look of the brass spacers and the copper showing through the acryllic glass stator plates.
This motor was made with simple tools, a jigsaw and a drill press.
If you have access to more advanced tools (cnc router would get you very far) the sky is the limit.
The triple stator version as shown above should make about 3 hp at 1000rpm. If you make it
better ballanced (cnc!) and you can spin it up to 7000 rpm -> 21 hp ! Make it a little bigger, maybe
1.5 times the radius -> power doubles again so now we're at over 40 hp ! go to 6 disks instead of 3 -> 80 hp !
So... instead of using a bicycle axle, if you make your own axle which feeds out the end of the
motor you can connect it to a gearbox. The example of Moto Guzzi (or BMW) makes it relatively
easy to mate the motor to the gearbox and you don't need belts or chains, and the input-rpm
of the gearbox is in the realistic ranges (few 1000 rpm)... Also an old guzzi or bmw should have
enough room in front of the gearbox to put a nice big Axial Flux motor, and an older bike still
has a classic frame good for simple motor support.
