Go on a segway experience with these personal transporters. Segways are mad little self-balancing things that will have you in stitches...not literally of course, but they really are fun to ride.
The technology behind them is quite amazing, but that's not what you'll be interested in when you opt for these adventurous experiences. As soon as you get the hang of how they work you'll be whizzing round with a big smile on your face!
