Electric bikes are getting more and more popular here in Norway (and we got hills and cold weather). Studded tires and an electric motor doing most of the work helps.

I know no one commuting on an electric bike...

I commute to work on an ebike when its too hot to use a regular bike. They are truely amazing. Riding an ebike was what got me started on riding to work.

a LOT of people in eg. Amsterdam use them daily. And I see more and more of those every morning and afternoon when I cycle to/from work.

I know a couple who do in Oslo, and I’ve seen others.

Holland has a lot of wind though, that can be very annoying as well. (And somehow it will change direction during the day so it will always be against you..)

e-bikes are massively solving the "last hill" problem with bikes.
