Riding an electric scooter is now officially legal in Queensland, but a change in regulation has come with a new $130 fine for anyone caught misbehaving.

The new rules, which come into effect on Friday, include a speed limit of 25km/h for "rideables", which must have effective brakes and nothing sharp that could injure a pedestrian.

Helmets must be worn while riding and users cannot carry a passenger.

Children under 12 are not allowed to ride and people aged under 16 must be supervised by an adult.
