the RTA is the place to check up on these things, for the real details, which can be printed out, laminated, and stored on the bike for rubbing in the faces of ignorant pigs.
as far as im aware, last time i checked...
no max speed limit anymore (used to be 30km)
no max capacity (used to be 30cc)
still retain the 200 watt max output.
bicycle has to be designed solely for human power, motor is merely an "assist"
by this reasoning, if you can restrict a 350V8 down to 200 watts, and mount it to something that can be ridden without the motor...perfectly legal
scooters are a no no.
and like every other vehicle on the road, be it a b-double, old-lady-walking or a 10-horse-wagon...you have to obey the road rules (unlike the junkie twit on highway patrol the other week with no helmet, wrong side of the road, a known dealer, carrying large quantities of illegal substances... giving us all a bad name!)
its because of all these sorts of idiots that the laws are so...grey, and definitely unfair.
write to your local member of parliment... once again, there are idiots out there that constantly send letters to politicians....thats why we have so many stupid laws. stop being complacent! send a letter or ten yourself! they dont know youre annoyed unless you TELL them!
ok, end rant!
