PassBox is a cycling safety study that measures how close cars get to your bicycle.

PassBox attaches to your bike and uses the same precision ultrasound technology used by police in the USA to detect passing events.

PassBox is collecting our third and final data collection in Melbourne. 

If you live in Melbourne, we need you to volunteer to put PassBox on your bicycle for two weeks. PassBox records all of your usual cycling and helps us understand what makes cars pass close. 

As a thank you for participating all participants will get a $50 bike store voucher and a one year cycling Australia membership including insurance. 

Help make cycling safer in Melbourne, volunteer now.
