My street lacks a bike lane. The hill is 10% grade and 35mph speed limit. I must ride in the right hand lane with traffic. I have no other road. I am considering this 3500 watt bike with a top-speed over 35mph.

Perhaps the bicycle tires are not designed to wear with the amount of force from a 5kW motor? Moped tires may be designed for that type of wear. I understand this bike does burnouts. Car tire codes and speed ratings.
E-Bike ready. The main sizes are approved and tested for E-bikes up to 50 km/h. The following sizes carry the ECE-R75 mark: 60-507, 60-559.
Adding turn signals, horn, lights and other legal requirements is easy.
Would they have to pass DOT regulation for them to say "on-road" use? There must be some test they would fail, like the tire tube overheating on hot pavement at the RPMs to reach 45mph.
USA bike tire standards are only 30mph, even though the tires are capable of much higher speeds, twice the test standards.
What is the worst-case scenario with a chain drop? Can a dropped chain bind up and break when the throttle is fully powered on a rear hub motor? If so, how to prevent chain from binding?
Is it possible for the rider to be thrown off the bike, like a motorcycle hi-sider, if the chain binds up?
What are other common dangers with a powerful rear hub motor, chain and throttle?
If the chain simply breaks, due to wear, could the chain get wrapped inside the spokes and cause a loss of control?
The bike has a Schlumpf drive, so is that the safest way to switch gears at very high speed?
