You can hear a soft sound as they approach. They look similar to skateboards but are actually quite different. They are longboards and are rapidly becoming a more common and stylish way to quickly get around.
Longboarding began in the 1950s, originally known as sidewalk surfing because riders would move in a way that resembled catching a wave. The boards got their name because they are much longer and wider than skateboards, usually between 90 and 150 centimeters in length. Every kind of longboard consists of trucks, four wheels and a long deck. The size and shape vary, however, depending on how a rider plans to use it. Unlike their shorter cousins, longboards are not intended for doing tricks. Their most basic use is for travel. Commuting (往返) via longboard is now common on college campuses in the U.S.. However, they are good for far more than travel.
Most longboarders enjoy the feeling that the board gives, a feeling similar to surfing. But some adventurous riders want more than a feeling. The sport of speedboarding appeals to these thrill-seekers who are looking for an adrenalin (肾上腺素) rush. Speedboards are designed for riding down hills at high speeds while keeping balance. Since the sport can be dangerous, riders usually wear suits and helmets, in the event of a fall. Those who don’t have the need for speed put their longboards to other good uses. Riders can compete in slalom (障碍赛) racing or long-distance riding, both of which require accuracy and strength.
If you want something completely unique, there is even longboard dancing. This stylish set of moves is performed while rolling on a board.
For feeling, speed or style, give a longboard a try. You might just discover you enjoy the ride.
