Ebikes or pedal-assisted electric bicycles are growing out of control in many countries, creating danger for other road users, robbing motorcyclists of parking and giving all riders a bad name.
There are now calls in Australia and around the world for regulation or registration for these vehicles.
In China it is so bad, more than 10 major cities have restricted or banned them, despite the bikes providing cheap and easy transport.
Many see them as a green transport alternative that free up the city and provide cheap transportation with some health benefits.
However, some Chinese authorities claim ebikes are dominating bike lanes, endangering bicycle, motorcycle and scooter riders as well as other motorists. They are also riding on footpaths and paying little attention to road rules.
Many other countries are now finding similar problems with the burgeoning growth of ebikes and the EU has complained about China dumping bikes in Europe.
There is a fear that they will grow even faster in the post-pandemic world where people eschew public transport because of the dangers of infection.
