Chinese dockless bike-sharing company ofo has announced plans to put 150,000 of its bicycles on London's streets as rival Mobike bring more of its bikes to the British capital.

Mobike rolled out 200 of its silver-and-orange bicycles in Islington, three weeks after competitor ofo dropped off 100 of its yellow cycles on the streets of the same North London borough.

The two bike-sharing companies are the largest in China and the main protagonists in the country's "bike wars", in which dozens of startups have competed for market share in hundreds of cities.

The two companies had launched in London boroughs previously - ofo in Hackney and the City of London and Mobike in Ealing - though Islington is the first place in the capital where the companies have crossed paths.

"We welcome competition in Islington, just as we did in Oxford when Mobike launched there several months after us," says Joseph Seal-Driver, general manager for ofo in the UK. "It's healthy and ultimately benefits the public."

Elsewhere outside of London, Mobike operates in Newcastle and Manchester and ofo hires out bikes in Cambridge and Norwich.

Steve Pyer, Mobike's general manager in the UK, says Islington is a good fit for the bike-sharing program because the borough has a "strong cycling culture".

"Islington is an important milestone in growing our presence in London," Pyer says.

The program differ from London's Santander Cycles - commonly called Boris Bikes - in that they do not use docks. Instead, riders use a mobile app to locate and unlock bikes and can leave them at recommended sites around the city.

Ofo announced on Nov 27 that it will work with the London Cycling Campaign, a cycling charity in the capital with 12,000 members. The charity will advise ofo as it rolls out the 150,000 bikes it plans to make available in the coming years.

Speaking during a visit to London in early November, ofo co-founder Zhang Yanqi said the fleet of bikes will include "e-bikes", or motorized bikes powered by electric batteries.

The company plans to bring some of them to London next year.

Zhang said he would like to see bike usage in London on a par with levels in Amsterdam.

Currently, around 2 percent of all journeys made in London are by bicycle, compared with 30 percent of journeys in the Dutch capital.
