Electric Unicycle
Electric unicycles are a transporter with a single wheel (you could have guessed by it’s name) that balances itself with gyroscopes and accelerometers , so it’s pretty hard to fall off it. I use mine to get to my work, as it’s 30 minutes away and by bike it’s not convenient because I don’t have a place to leave it for 8 hours, but with the unicycle I got from https://myewheel.com/ I just pick it up with me in my office. Pretty cool thing all around.
