In the 80s Honda had the idea of a tiny collapsible motorcycle that could be stored in the back of a tiny hatchback. Today they have an electric version of that original bike.

The old bike had a suspension and higher top speed. The electric bike has faster off the line acceleration, folds up to a much more compact size, weights less than half the original bike, and doesn’t stink of gas if stored in the back of a car. Considering the same dry state of many roads and sidewalks,…I don’t see this being a viable park and ride vehicle option. Watching them ride in the parking lot make me think of zipping through a large airport. Not positive, but it may be small enough to take as a carry-on.
