Nearly 400 three-wheeled electric scooters developed by a Chinese tech firm are now available for rent on the streets of Miami and five other cities in the United States, the Shaoxing Daily reported on Aug 9.

The black-and-yellow scooters called iMigo produced by Zhejiang Doohan Technology Co can run up to 100 kilometers on a full charge, with a maximum speed of 45 km per hour.

Similar to popular bike-sharing services such as Mobike and Ofo, the scooters have chips installed in them that allow them to be located and unlocked using Doohan's mobile app.

The company claimed it has released more than 1,000 such scooters in China and abroad so far. The number is expected to rise to 3,000 by the end of 2017.

The rental cost is $3 per hour in US, and 100 yuan ($15) per day in China.

"With concepts of 'shared economy' and 'intelligent manufacturing' on the rise, there is no reason for Doohan not to cash in on the new opportunities," said Huang Jingliang, the assistant to the company's chairman.

Based in Shaoxing, Zhejiang province, the tech start-up owns nearly 30 patents for its e-scooters, including core technologies in the balancing, damping and smart control systems.

The company also offers customized design services to its clients. It added sirens to a fleet of scooters provided for police in South China's Guangxi Zhuang autonomous region.

"With first-class design, manufacturing and services, Doohan is a prominent example of big data and smart technology application in Shaoxing," said Zhang Xiaobin, secretary general of the Shaoxing Industry and Internet Association.
