This was one of the reasons l wanted folding Ebikes, less hassle
A folding bike, due to the requirements of its design, has folding parts and hinges, that no matter how good they are made, are never as solid as good, solid/tubed metal.
They will over time, even if lubricated, wear and slowly get looser.
Their lubrication will get on your clothes and skin.
They also add weight!
Carrying shopping can be a trial with a folder, and certainly cannot compare with the amount of shopping my bike in two panniers and a rack, though I have not needed a basket up front till now.....
For me personally, there are no plus points in a folder.
On a normal bike, dropping the front wheel out, with a quick release, shortens it dramatically. Then turn the forks 180° and the handlebars 90°, and you have close to a folding bike length and width! Often with far less aggravation....
