Recommendations for men E-bike for max 3k Fr.-?

Looking for an electric bike (city, maybe some trails in nearby forests, no need for mountain bike).
Speed is not important, 25km/h is fine. Ideally it can go about 100km. Used mainly on weekends.

Also need to hang a croozer with 2 kids.

I was thinking at those from Decathlon but also Leonardo from Jumbo.
Any recommendations? Can also be second-hand if it's not too old, I don't mind.
