200watts, and keeping it under 50kph it legal.
over that, pretend to pedal, dont attract attention to yourself. you will be good.
go to the local trophy shop and get a plate convincingly made engine plate, that has the following engravings on it:
200 watts engine output
a serial number
anything else that will make it look pro
failing that checkout these fully legal 200watt petrol ht engines.
by memory, just the RS 200watt certified engine is about $160+p&p by itself.
I dont have a problem with the feds in the ACT. I just dont do any lewd acts in front of them.
