The acting Queensland Transport Minister, Steven Miles, has announced the government's decision to change the law concerning power-assisted bicycles.

Illegal high-powered bicycles are commonly leased or sold to unassuming tourists in the Gold Coast and present a safety concern for pedestrians on the footpath.

Mr Miles said bicycles on the footpath must have pedals as their main source of power and new laws make it clear the motor cannot operate without the rider pedalling at speeds greater than 6km/h.

The Minister encourages companies hiring out these vehicles to ensure their devices are legally allowed to be used on footpaths.
