SINGAPORE - He had just bought the bicycle from a second-hand seller.
But when student Sean Lim En Wei took it for a spin at a carpark near his Woodlands home last June, it could have cost the 17-year-old his life.
Its brakes were probably faulty, State Coroner Imran Abdul Hamid said at Friday's coroner's inquiry into the teen's death.
The Jurong Junior College student had left home at 8pm after dinner with his family on June 9.
Together with a friend, he cycled to a multi-storey carpark at Block 625A, Senja Road on his red bicycle.
Sean's friend, who was not named in the inquiry, checked Sean's bicycle and was concerned about the state of the brakes. But Sean cycled away from his friend, leaving him behind.
As he cycled down the ramp, from level 5B to 5A, he picked up speed.
He was cycling at a minimum of 10kmh - his actual speed could not be determined - according to a report by an accident reconstructionist.
The coroner's court heard that Sean could have tried to brake, but failed to do so due to a "possible brake problem".
Instead, he could have used a parking lot kerb at lot 547 to stop himself.
