Shanghai's transportation commission is investigating a media report that the ofo bike sharing company is furtively putting new shared bikes on the streets in defiance of a ban that the commission made regarding shared bikes last August.
Ofo is to be questioned on the claims later this week, the commission said.
A press report said new ofo bikes were spotted in the center of the city, some of which had been disguised to appear as used bikes and therefore not subject to the ban.
"We are not adding more bikes. We have reduced the number of bikes in Shanghai by 50,000," said Liu Wei, of ofo's publicity department. "The bikes in the report were replacements for scrapped bikes."
