Teenagers going on regular “ride-outs” in Perth’s northern coastal suburbs have been warned their e-bikes are actually illegal and will be confiscated and crushed by police if they are caught. WA Police Commissioner Col Blanch put riders on notice on Tuesday, confirming that, in the eyes of the law, e-bikes with a maximum speed of more than 25km/h were considered unregistered motorcycles. Riders must also be over 16. The ride out in North Beach at the weekend. “They are going to be seized and destroyed every single time, there is no giving them back, they are always heading to the crusher because they are not able to meet the registration requirements of state vehicles.”
