Thanks for the advice! I'm in Europe :)
What I'm afraid of is pushing myself so hard that I have to go home early :( I like biking long distances which makes me afraid to push myself too hard, which would (possibly?) severely cut my distance capabilities.
Unfortunately, I have no car :(. Most ebikes on the road by me are ridden by couriers and they're just speeding along the road way going 2-3x the speed of me - they're quite popular here.
A lot of the times I push myself to pick up speed so I can coast for a while after, though this is probably counterintuitive in a way.
