@matigo I have the type with a rectangular top tube, inside which goes the battery. Every time I want to ride, I have to release two catches, fold the bike, insert battery, lock with key, yank the loop on the battery to make sure I locked it properly, unfold the bike and snap the two catches again. There are different degrees of faff: mine is a lot of faff; if it’s electric but the battery is outside the frame it’s a bit less faff; if it’s not electric, there’s even less faff. But most folding bikes (not mine though) get you to fold the seat and bar too. The thing that always catches people out with folders is the weight. They see a picture of one and think 'ooh, that’s nifty. I’ll get one and store it in the hallway in my flat'. Then they get a shock when they go to lift it (especially the electric ones).
