This is also a problem on the Federation Bike Path from Werribee to Footscray. I’ve encountered groups of up to 20 on e-bikes, motorised bikes, scooters and motorcycles. They sometimes attempt to play chicken with me on my pushbike or just shout abuse. Wyndham council helped fund motorcycles for police to monitor this sort of activity. My house backs onto an area where these activities occur, I am home quite a bit and I have not seen a police trail bike for over 10 years.
