Your right Queensland clearly state that the use of a petrol assisted bicycle to make the 200watts is prohibited but NSW says you can use a petrol motor to make the 200watts.
Fully aware that when they made the law it would mean that most petrol motors would be excluded.
What petrol Motor do you know of that will push a bike that is 200watts or like 9cc
It doesnt phase me either way. but instead of this go into a police station with a pic or even take ya bike and ask em for yourself.
