The new bike-sharing phenomenon is a lifeline for all those frustrated city workers who have had enough of their daily commutes. With so many bike-sharing services to choose from, more and more people are leaving their cars behind, ignoring public transport and jumping in the saddle instead. But with their heavier wallets and extra convenience, there must be some people losing out?

Bike-sharing company OFo announced its largest ever injection of capital last week. It received 450 million dollars from a trio of private investors and, in the process, became the first bike-sharing company to be worth more than 1 billion dollars. Ofo has more than 20 million users in nearly 40 cities in China, Singapore and the UK.

However the bike-sharing boom hasn't been well received by everyone. He Changlun, a bike store owner, has run a very successful business for the past five years. But this new bike-sharing service has really caught him off-guard.

"I haven't been able to sell my traditional bikes since this bike-sharing service began. We have only sold a few bikes since the start of the year. We might have to think of moving our business to other cities,” He said.
