A young man in Wenzhou, Zhejiang Province, climbed the stairs of a 33-storey building by bike last week.
The unusual bike ride took 24-year-old Zhang 33 minutes and 48 seconds to complete.
Zhang is already the holder of four national records for extreme sports.
He is now planning to climb the 420-metre Jinmao Tower in Shanghai by bike by the end of this year.
