Zhong Li Fong, 38, crashed at 1am in front of Ujareon Village in Pa Khlok.
A friend of Mr Zhong, who was riding another bike behind him as they made their way back from Patong to Cape Yamu, where they were staying, told police, “He was driving through some curves when he went straight on into the ditch and hit a pipe on his way down.
"I think he must have fallen asleep because it was quite late.”
Mr Zhong was initially taken to Thalang Hospital and was later transferred to Vachira Phuket Hospital.
