I bought a 6 speed C line with dynamo for Christmas and I love it! Really fun to take the train and discover new areas. 40km yesterday between France and Belgium.
Easy to put in the car as well. We have also normal bikes and a bike rack but as we live in the city center with a parking spot nearby we use them only for multiple day tours. The Brompton is always ready to go!
My wife rides an electric one since a few years for commuting. On a tour like this she uses lowest assistance and only about 20% of the battery so range is not an issue at all. Rolling resistance is really low apparently, you could ride motor off. When going to work she uses medium assistance and the frequent stops consume more.
