Range goes way up – electrification can turn a 10+ mile commute from something intense (where you need a shower when you arrive) into something manageable.

It allows bikes to be a substitute for far more things that you'd otherwise use a different mode of transportation for.

Put slightly differently, electric bikes (and scooters for that matter) make those transportation forms accessible to a much larger number of people.
