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.

*only one battery per race. 

Would you take 5% boost for the whole race or be 2x faster for 10% of the race? but have to carry the extra weight up the mountain?

probably advances electric bikes the same way F1 advances car tech. makes cycling more broadly exciting.
