Amateur; thanks for your reply! I will look around. I think 34kW peak and 16kW continues would be enough dor my project. Need something of capable of doing Vmax 70-80 mph, but I am more for acceleration as for Vmax.

it's the front, the rear is just spring loaded.
what's different to the systems I know (mopeds), is that the clutch is at the rear and not at the front.
Thanks - that makes more sense: they have a centrifugal clutch (strangely at the rear), in addition to the variable pulleys (with the control at the front as it should be). As I recall, snowmobiles just let the belt slip on the input pulley until the engine turns at high enough speed to cause enough clamping force (they even call the pulley control system the "clutch"), and this is much better. That clutch (mounted at either end) is certainly not required - or wanted - with an electric motor. A non-slipping belt-type CVT might work well, keeping the motor in a more useful speed range, although with the right motor it isn't necessary.

An off the shelf CVT (comet 20, 30, 40 series etc) could be modified to more appropriately work with an electric motor. This would be done by modifying the driving pulley of the CVT so that it would simply grip the belt in it's relaxed state. The spacing of the pulley halves is determined by a spacer on the shaft, this would need to be ground/turned on a laithe. Likely a little guess/test would yield the best results! Non slipping CVT's are common in industrial applications as opposed to vehicles.

Neematic clone

As some of you may find out, my last project was literally cut to pieces.
After a loss of inspiration to finish my first project I came across a picture of the a Neematic bike and was floored by it's stunning Beauty. I am particularly captivated by the trellis style frame commonly seen on Ducati motorcycle's.
So here go's round number two.
