Summary
Yes, when part of the commute happens off the bike: a train leg, a small apartment, an office with no bike room, or a car trunk. In those cases the fold is the reason to buy it, and the details that matter are the bike's weight, its folded size, and how quickly and cleanly it folds. If the bike would ride unfolded every day and park in a garage, a conventional commuter e-bike gives you larger wheels and less hardware for the same money.
The fold has to solve a problem you have
The fold is useful when a full-size bike cannot come with you or cannot fit where you live. Riders who fold twice a day, at the station and at the office, get daily use out of it. Riders who never fold carry the extra joints, latches and smaller wheels for nothing.
Small when folded is not the same as easy to carry
A bike can fold into a tidy package and still be miserable to lift. Rolling a folded bike across a lobby is one thing; carrying it up two flights of stairs is another, and there the complete weight decides how far you get. On models with a removable battery, the weight with the pack out is often what actually gets carried.
Closets, trunks and trains have their own limits
"Folds small" is not a measurement. Measure the closet, the corner of the office, the elevator, or the trunk opening, which is often smaller than the cargo floor behind it.
Trains have their own numbers. Amtrak allows folding bicycles under 34 x 15 x 48 inches on board in place of a piece of luggage, and only "true folding bicycles" count. Its rules for electric bikes are separate: lithium-ion batteries certified by a nationally recognized testing laboratory, a maximum weight of 50 pounds, tires no wider than 2 inches, a motor under 750W continuous, and a top motor-only speed of 20 mph. Many folding e-bikes with 20 x 4-inch fat tires or weights above 50 pounds fall outside those limits. Amtrak does not say how the two sets of rules combine for an electric folder, so a rail commute built around one needs a direct answer from the railroad first.
What makes one fold slower than another
A demonstration in a shop makes almost any fold look quick. On a platform with a work bag on your shoulder, the details show: pedals that fold or stick out, a stem or handlebar that has to be adjusted, a magnet or latch that holds the halves together or leaves them to swing apart, cables that get pinched, and a folded bike that stands and rolls on its wheels or has to be carried.
What small wheels change
Folding bikes usually run 16- or 20-inch wheels to keep the package small. Small wheels drop into potholes and over cracks more sharply than full-size ones, though wide tires, lower pressure and suspension can take much of that out.
