There have been many interesting transport inventions. Some become popular, but others flop!

The personal hover scooter floats above the ground. It travels at around 30 kph. But it isn't popular. Maybe that's because it's too expensive. Personally, I think it's too hard to park!

The monowheel is a single-wheel bike. The driver sits inside the wheel and pedals to go forward. It has one major problem – it can fall over very easily. I think it looks rather weird.

The Segway is a success. It's a two-wheeled vehicle. The driver pulls the handle to go back or pushes it to go forward. It's not as popular as the inventors hoped, but you might see one in an airport, or park. I guess it is a convenient, green way to travel.

Which new inventions will we use in the future? Which ones won't we use? It's hard to know!
