A better bicycle rack
Most bicycle bays in HDB void decks make it hard to lock up anything more than one wheel - so you could come back to find the rest of the bicycle gone.
Five young grassroots volunteers came up with a solution: a rack with metal bars that can be locked around the bicycle frame.
The front wheel can also be secured separately.
"This makes it much harder for theft cases to happen," said Or Jia Yun, 19. She and the rest of the team, all students aged 19 to 20, are members of Woodlands Community Centre's Youth Executive Committee.
Her team-mate Anas Rahamat, a keen cyclist, hopes the HDB will put their design into use.
"I've been thinking about (bicycle safety) even before the competition," he said. His brother's bicycle was once stolen from a rack outside a shopping mall.
The HDB, for its part, has called it a "simple yet clever design that is easy to use".
