Thanks for your help.
My idea is that the axle from the Motor is 90 degrees to the driving axle. So the M-Motor Comes from the top .On the axle from te M-Motor
should be a 20 tooth double bevel (piece number 32269) and on the drivin axle a 12 tooth bevel (Piece number 6589).
And I want to use this idea for the 2 axles on th rear wheels.
