It's quite cold a lot of the time in Northern Europe, and people who are cycling to commute there often really aren't going very fast so won't sweat much.

You can also get "moisture wicking" clothes, that might help with a certain amount of sweat.

There is quite a lot of e-bike use in Amsterdam and Copenhagen. Google "bakfiets" - it's a whole "suburban parents with a family size e-bike" cliche (but a good one!).
