At the point where you’re happy traveling at or below 15mph for 1.5mi total a day (so two trips of 3/4mi), the effort involved is nearly nothing.
Just for handy reference, 10mph is a mile every six minutes. So we’re talking about bike trips on the order of about five minutes at a very low intensity.
And as a sibling noted, foldable bikes exist and are smaller, lighter, and cheaper than this.
Being heavy when riding isn’t that bad but being heavy when carried up stairs is.
I love the novelty of this; it’s James Bond’s scooter. It’s a wonderful concept, collector’s item but not a serious means of transport.
Personally, I’d rather have a 7.45kg non-electric Brompton than a 19kg scooter with a short range.

Another concern I'd have is tail spray from the back wheel in wet weather, I've had clothes stained from a similar mechanism in the past.
Most commuter bikes and folding bikes come stock with fenders which eliminate tail spray.
