So how does one set up an e-bike race so that it tests the bike rather than the rider? Or, rather, so that the machine's contribution is more important than the rider's physical power.
Phrased like that, the answer becomes clearer. It may never be possible to fully discount the rider, but making him a minor component is possible.
An e-bike operates over a range of conditions - different speeds, above and below cut off (if there is one), hill climbing, etc. There are some regimes where the motor power dominates, and some where the rider power dominates. All that is required is to configure the race so that it emphasises the right parts of the envelope and avoids the wrong ones. It really is that simple.
For instance, at 20 mph on the flat on a UK road legal bike, it is all rider power. But the same bike climbing a steep hill might put out a peak power of 500 W, compared to the rider at 100 W.
So the very worst thing is a simple course on the flat, with no slowing down and accelerating. Restricted bikes are pedalled above their 15 mph cut off speed and de-restricted ones are pedalled up above the voltage cut off speed.
But consider another type of course; alternating hill climbs and descents. If the climbs are anything other than trivial, then the motor contribution dominates on the way up, even over professional muscle. Going down the other side, we are probably above the speed that even a de-restricted motor can contribute. The motor power will be nil, but then the rider's input is negligible too. Gravity is doing all the work.
An uphill and downhill course works for both restricted and de-restricted bikes, there is meaning and validity to the exercise. The important things are now the bike performance and the rider skill. Suddenly most of the questions are answered - there is a point.
It looks like it really is that simple. And that was only one idea for a race - we must be able to dream up others.

PS. The uphill and downhill course is not just a theoretical exercise, it is not so far removed from what a few of us are doing next month on the Tour of Britain course. This was the challenge laid down by Mr Ching; initially he got a cynical reception, but when I started thinking in detail about how best to get round the course, I suddenly caught on and signed up. Mr Ching was unfairly criticised for what we should now be viewing as an inspired suggestion.
