An international exhibition of electric vehicles opened in Tianjin on March 24, during which intelligent bicycles which make cycling more convenient and easy have attracted visitors' eyes.

"Cloud bicycles", which can be obtained simply through swiping magnetic cards, caught people's eyes, particularly seniors who are not used to using smart phones to scan QR codes on public bicycles, which has become increasingly popular among urban young people.

People only need to swipe cards to trigger censors on the bikes, and the lock will be opened automatically. It plays a voice prompt when the rider is venturing out of the limited range.

A concept intelligent hybrid-powered vehicle at the exhibition also attracted many visitors. People can ride the bicycle by themselves and when the travel distance is long, riders can switch the bicycle into an electric one.

Meanwhile, the vehicle can monitor and record riders health condition.
