Jackrabbit’s micro bike (or scooter?) lets you do basically that. While Jackrabbit has a top speed of 20 mph, ti weighs just 24 lbs. and can be compacted even further by folding the handlebars down and taking out the seat post.
If you’re ready to make the move to a micro bike, you can buy the Jackrabbit right now, with an expected ship date of January 2022. Not in time for the holidays, but if little e-bikes are your thing the Jackrabbit looks well worth the wait.
