【題目】 If you’re looking to buy a gift for your children, why not keep up with the trend and get the best hoverboard?
What is a Hoverboard?
A hoverboard is a two-wheeled personal transportation device. It’s electrical, portable and became highly popular in 2015 in reference to a popular 1980’s movie. Typically, this self-balancing device operates like a powered skateboard.
How Does a Hoverboard Work?
The device may have many designs, but the mechanism itself isn’t complicated. Basically, a standard hoverboard contains:
Battery: stores the electrical power. Almost all hoverboards use a high-watt lithium-ion battery.
Gyroscope (one for each wheel): allows riders to tilt (傾斜) the hoverboard while maintaining balance and adjusting their direction.
Motor (one in each wheel): provides the power to the wheels to keep the rider balanced and upright.
Logic board: functions as the hoverboard brain. It processes data — your speed, tilt, etc. — and sends information to the motors. This unit controls the power of the board so riders can adjust their speed.
All the above components work together to control the power and tilt of the hoverboards so the rider is balanced, upright and moving at a controlled speed.
Why Buy a Hoverboard?
Undoubtedly, hoverboards are cool. You’ve probably seen kids riding one around the house. They’re a phenomenon and everybody wants in. So, why deny your kids and prevent them from being part of this trend?
Where is a hoverboard legal?
Despite their wild popularity, hoverboards have yet to become “street-legal”. Currently, some places prohibit anyone under 16 from using these devices, and hoverboards are banned in academic institutions and public places, like campus buildings, parks, shopping malls and subway stations. Some places have also put speed limits on the devices and restricted their use to bike paths. However, open areas — including your yard — are free of these restrictions.
