Dozens of young ebike riders have raised alarms after riding over a golf course green in north Sydney. On Friday, about 60 ebikers rolled across the fairways of Long Reef Golf Club, causing concern over turf damage and safety. Police were alerted but found the riders had already left. The next day in Melbourne, around 100 ebikers took over city roads before meeting up at Docklands. These “fat bikes,” known as the monster trucks of cycling, are popular with youth but have sparked safety worries. Peter McLean, Bicycle NSW chief executive, said, “There’s lots of benefits that go along with them, but when we have really high powered ebikes and people driving them dangerously and without helmets, then they certainly pose a significant risk.” Ben Russell, General Manager of Long Reef Golf Club, said there was no major damage but confirmed the acts were disruptive. He added, “Over the past 12 months, the club has experienced an increasing number of vandalism events involving ebikes entering the course after hours, skidding on greens and fairways, and damaging maintained turf areas.” To combat this, the club is installing mobile CCTV towers. Victoria police are investigating Saturday’s Melbourne incident where riders were caught speeding, riding on the wrong side, weaving among traffic, using footpaths, and running red lights. Pedestrian Council CEO Harold Scruby highlighted the dangers, noting many bikes are illegally modified and resemble motorbikes on footpaths. In response to growing worries, NSW Premier Chris Minns recently announced plans to cut ebike power to 250 watts to limit top speeds following a fatal accident. McLean said a national regulatory framework is needed to control ebike imports and promote safety. Transport ministers agreed last November to work on laws to keep ebike use safe and consistent across Australia.
