Have you Onewheeled?

The OneWheel:
It's a powerful smart device that you ride kind of like a snowboard (more like snowboarding than skateboarding) It's got one big wheel with the motor and gyro. You lean forward it goes faster, you lean back it slows down. If you lean back enough it will stop and then you can even go the other way. This thing had head lights and tail lights and if you change directions the lights change.

The App:
There is an app so you can connect the Onewheel to your phone, it tracks your milage, speed, battery life, and type of riding (yes there are different settings for different terrain).

The original one wheel gets about 5-8 miles of riding and goes about 15mph. The newest Onewheel get about 12-18 miles and goes 20mph. It doest just ride on the street, but it rides on grass, gravel, sand, trails, and even snow (to some extent). It even cruises up steep hills. On top of all this, it is so much fun! The price tag is a bit steep, but there was a lot of R&D to make such an intuitive device and I find it worth every penny! It's one of those things you have to try to justify it.
