Скачать или смотреть Jyrobike : This bike balances itself

Training wheels are great for getting kids rolling, but they don't really develop the balance required for real riding. Jyrobike takes a different approach to the learning process, providing a more authentic cycling experience while still offering the stability new starters need. That's because it's self-balancing, and though that sounds too good to be true, the technology that makes it possible is actually quite simple. Contained within the front wheel is a weighted, motor-driven disk that gets up to several thousand revolutions per minute (RPMs). This spinning disk, which emits a dull hum when at full speed, exerts a gyroscopic force that pushes against the turn and lean of the front wheel. As the rider tilts towards the point of no return, the front wheel corrects and as a result, nudges the child into a balanced body position. Watching someone ride a Jyrobike doesn't give you a good idea of how stable the thing really is, but we were incredibly impressed by a live demo. With just a small amount of forward momentum, the prototype easily shrugged off sideways slaps with only a slight waver.
