That's an impressive build (OP) and good choice of bike.
You mentioned blurring the line between ebike and e-motorcycle.
The thing is, inertia becomes a friend in certain situations. Take big wave surfing for example. When the waves are twenty feet (generally considered the size in which performance is pretty much irrelevant and surviving the take-off and maintaining speed is the focus), you want a big, heavy board. It paddles faster, cuts through chop better, and sticks to the wave better while keeping your speed. The guys who surf Mavericks in California or Waimea Bay in Hawaii (and other big-wave spots) are trying to paddle hard, fast, catch the wave, make the steep drop after standing up, and reach the shoulder of the wave (the outer portion that isn't breaking) and avoid the huge mass of pounding, whitewater just behind them. It's the thrill of the drop that they're after, and the ability to turn sharply isn't that important.
However, on smaller waves (in the pro category that generally means ten feet and under), you want a light, thin, smaller board designed to turn on a dime so you can perform radical maneuvers as close to (or inside) the breaking section of the wave. You generate your own speed through "pumping" your board in the water.
So, a bike is the same way. If you really want to go fast...really fast....then you want a ton of power and a lot of weight. Get a motorcycle. Electric or gas, a motorcycle is much safer than a souped up bicycle.
That's just my opinion. I've ridden a friend's ebike that was 96 volts and I had to really nurse the thumb throttle on take-off to avoid a wheelie and eat it. It could hit about 45mph or so, and I wasn't comfortable.
Heck, mine hits 29.2mph, and I don't like that speed.
Having some power is cool, though, but unless you're experimenting, etc., why would people want to go so fast? Maintaining 30mph for even a few minutes on a bicycle isn't safe. Too much can go wrong (I'm not really talking about dirt and stealth bikes, etc. They are built for that).
Just my opinion.
