"Loop is a high-speed underground public transportation system in which passengers are transported on autonomous electric skates traveling at 125-150 miles per hour.

Electric skates will carry between 8 and 16 passengers (mass transit), or a single passenger vehicle," the infrastructure and tunnel construction company says on its website.

The electric skates are faster than conventional subway cars, and are autonomous vehicles.

As the Beijing 2022 Winter Olympic Games kicked off on Friday, over one million people flooded the official Tmall store of the Olympics and rushed to buy a Bing Dwen Dwen mascot, the cuddly Panda on ice skates, and other merchandise, according to a report by the e-commerce giant Alibaba.

Compared with ski sports, ice skating products like figure skates, speed skate sharpeners and ice hockey sticks surged by 553 percent, 420 percent and 328 percent year-on-year, respectively.

The upcoming Beijing 2022 Olympic and Paralympic Winter Games have fueled interest in winter sports, as evidenced by the large number of people browsing related products and queuing up to try the alpine skiing simulators and skate on the artificial ice rink at the fourth China International Import Expo in Shanghai.

"We are seeing with personal mobility that some people like to skate; some people like to scoot, and some people like to ride," said Swagtron Chief Operating Officer Andrew Koven.
