It's called a "Trikke"

It's called a "Trikke, and it looks like a three-wheeled scooter. Only you don't scoot it. And it's a lot safer. Both feet stay on the Trikke (near the back two wheels), and you propel it by rocking from side to side.

It's definitely not what you'd call an "effortless" means of transportation. But effortlessness is not what the Trikke's all about. It's about exercise and fun - and anything that's able to put those two experiences together is worth serious consideration.

It's best on flat, dry surfaces. Since you have to move the vehicle right and left in order to move forward, it takes more sidewalk room than a bike or scooter. But it's one of those things you can get better and better at - until you get good or wacky enough to consider Extreme Trikking, as demonstrated in their collection of videos.

Three different Trikkes are available - one for kids and people who want to do skatepark things, one for the more mature, looking for exercise and transportation, and a third people who don't want to make up their minds.
