I got an e-Muli, which is a sorta “short john” but where the front basket folds and handlebars pivot 90° so parking it is a bit more slim, more or less the footprint of a normal bike. It’s amazing — a little heavy so probably not luggable up stairs, but small enough when basket is folded that I prefer it even on errands where I don’t need the cargo space, just cause it’s electric (nice to throw a backpack in the front basket and close it, too. A little pricey since it’s made in Germany, but absolutely worth it: https://muli-cycles.de/en
