Maybe that’s why the “elektrische bakfiets” (electrified cargo bike) is really popular here in the Netherlands. I’ve got one and don’t even live anywhere near an airport, closest one is at least an hour by car.

Depends how much luggage exactly, but bakfiets and cargo trailers can be pretty roomy. Ebike is always helpful.

And that's before you get into tricycles.

I've biked to the airport lots of times. It depends on where you're going of but for short-ish trips a backpack is often though. And I did also once bring a suitcase on a (non electric) cargo bike. Worked fine.
