"Le marié est entré dans l'église en trottinette."

Translation: The groom entered the church on a scooter.

[Lng52-._]

Could you also say, "Le marié est entré dans l'église sur en scooter"?

[Jojo553168]

It would be sur un scooter or en scooter. But that would not mean the same as trottinette.

Un scooter	Une trottinette

[auyuittuq]

you could say "en scooter", the sur isn't needed because 'en' already tells that the person uses it.

Why is it "en trottinette" instead of "à trottinette"? You are not in a scooter. You are on it.
