A Queensland report has found that half of the e-bikes and e-scooters in the Australian state do not meet legal requirements. The finding covers the two main categories of electric mobility devices involved in the study. It comes as owners approach the deadline to obtain a sticker proving that their vehicle is legal to ride. The result means many riders may still need to regularize devices they already own. Without the required certification, an otherwise roadworthy e-bike or e-scooter can remain non-compliant. The findings leave authorities facing a sizable task as the deadline draws closer.
