I'm long electric cycling. 

Bikes are a technology, electric ones are better.

Tour De France and others would be 10x more interesting with electric bikes and constraints like only battery per race and a weight limit.

Tradeoffs and strategy become fascinating while improving the tech. Athletes still have to athlete.

No way! 
Cycling is about pain.
You and your bike.
Nobody wants to watch e-bikes…

Sprints are already extremely dangerous. 

You don’t want to make them any quicker.

Are you a road cyclist yourself?

Greg Lemond, a famous cyclist, had a famous quote "it never gets easier, only faster".

I would bet a lot of money that cyclists would still need to exert maximum energy to win, and the only thing that is changing is that they are going faster than before.

Like going from a heavy bike in the 50s to a modern one today.
