As they were half-way down the slope along Jalan Wat Siam last Sept 7, Madam Lee Yan Inn, 41, had asked her 15-year-old daughter whether she wanted to go faster for more thrill.

The girl did not reply.

As the bicycle gained speed as it was going down, it jerked up suddenly while going over a hump, causing both to fall off the bicycle.

Madam Lee suffered serious head injuries and was conveyed to Changi General Hospital where she died 11 hours later of a contused brain due to a broken skull.

Her daughter suffered some bruises on her right hand, right shoulder and legs.

An investigation report tendered at a coroner's inquiry on Tuesday said Madam Lee's husband, Mr Tiew Sin Keng, 44, was cycling behind them when he noticed that she had picked up speed while cycling down the slope.

He was cycling half-way down when he saw that his wife's bicycle was already nearing the foot of the 116m-long slope.

He subsequently heard a loud scream and saw his wife and daughter flung out from the bicycle.

Mr Tiew told police that this was the second time his wife had cycled within the island. Nothing happened when she was there in 2006.

State Coroner Victor Yeo recorded a verdict of misadventure on Madam Lee's death on Sept 8, saying it was indeed an unfortunate cycling accident.
