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.

After collecting data in Melbourne, Geelong and Bendigo - we are now in Perth. 

If you live in Perth, 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 free one year cycling Australia membership including insurance. 

Help make cycling safer in Perth, volunteer now.
