Electrically assisted bikes, trikes, etc.

For riding on private land and trails I am thinking of moving the speed sensor from the rear wheel to the crank. I fully understand that this is not legal on the road and could invalidate any warranty, so please don’t feel inclined to remind me of these things. The consequence is that the bike electronics are tricked into thinking that cadence is actually speed and because cadence is a lot lower than rear wheel revolutions it allows the 15.6 mph limit to be exceeded. One inmediate problem is that the speed display is wrong but that can be overcome by using a Garmin. My question however is how would this modification impact the delivery of power and the application of torque?
A friend tried that and after a few hours he got an error code and had to switch it back
I wish it were as easy as riding a bike
