HI guys.
i can not believe the ruling from that judge in NSW?
Horsepower is a given unit of weight moved over a given time and distance.
1HP is exactly 0.45359237 m·kgf/s
that's meters, per kg, per second.
we want 1/4 of that to be under 200w
so, to find out your bikes actual horsepower output with a few hundred years of science to back it or yourself up in court if you ever need it. - weigh yourself with your bike. get on it and ride a set distance and measure your time.
as an example. My combined weight is 100kg, 220 pounds- doing a 1/4 mile in 60 seconds. is 0.24 HP that is under 0.27hp... or 200 watts. im geared to do that time.
Remembering just to keep it all quantified, a brand new police car would struggle to do it in 15 seconds!
Tas legislation:a pedal cycle with an auxiliary motor (or motors) with a power output (or combined output) of not more than 200 watts.
If our legislators or the courts / police or anyone else wants to measure the output of the motor alone- they need to call for torque. the rotational energy of the motor! not HP, they are different measures!
i would hate to see anyone get in trouble because of a very non scientific court ruling. hopefully the above helps us all get /stay out of trouble. ;-) too
The above is just using a very well known measure of power using science to back it up.
it is very provable and repeatable! And, is exactly what they asked for in their legislation!
There is also nothing in regard to speed on your bike in RTA NSW apart from wheelchairs and mobility scooters, so that judge not only made up his/her own bit of backyard science, he added new laws and conditions as well, bypassing legislative council, that may affect everyone in the future?

I would if i was Mr Bozinovski get a real lawyer (no offense to his other one) but they obviously did not do their job! IMO and get an appeal going straight away.
Kindest regards
Phillip
