The fire wrecked almost all the motorcycles parked in deck D which is above a 24-hour coffee shop.

Undergraduate Kim Lee, 24, who was up late studying for her exams in her flat, said she heard loud popping noises coming from the carpark opposite.

'At first I thought there was an army training going on at a camp nearby but I looked out of my window and saw a huge fire coming out from the deck where the bikes were,' she recalled.

Ms Lee quickly woke her boyfriend, David Tan, 25, and called the fire brigade. They both own a motorcycle parked there.

They then rushed to the carpark, and with the help of about 10 others, tried to tame the fire with the hoses situated there but were overwhelmed by the huge flames.

'It was all ablaze like an enormous barbecue. There was just too much smoke and too much fire and we really tried our best to save our vehicles,' said Ms Lee.

Ms Lee and Mr Tan lost a class two race motorcycle that cost up to $18,000 with insurance. It was Mr Tan's main mode of transport.

The Singapore Civil Defence Force (SCDF) said that they received a call at about 2.30am and dispatched a fire engine, a red rhino and a support vehicle.

The fire was under control 15 minutes after SCDF arrived at the scene.

The cause of fire is being investigated.
