Hello,
i was wondering if anyone had see these restrictor systems zbox has. i was thinking of getting one for my motorised bike but the only thing is my motor isn't a zbox i bought my motor of ebay, would that be a major problem and does anyone have instructions on how to install these things so i know if it would be to hard to install for myself? Here is the link. the system is at the bottom of the page the reason of wanting one of these is to make my bike legal in NSW australia

Thanks in advance -Bazz

I hope you realise that a 200 watt engine is less than useless.

I also hope that you realise that it's up to the discretion of the police officer to issue an infringement notice (even if your bike complies with the law), then if contesting the fine in court, it will be money coming out of your wallet to fight it through the legal system, of which the police force can simply appeal the decision as many times as they want till you run out of money trying to fight the case in court.

A friend of mine is a Highway Patrol Officer and those guys can make your life very difficult if they don't get their way.
 
Has anyone actually got one of these 200w motors or the restriction kit? what does it include? what is the difference between a 200w motor and our normal motors? can anyone post pics of their 200w kit?

i want to make my kits look as close to a 200w one as i can to help talk my way out of any encounters with mr law (i realise they can do me regardless but i want to give myself the best chance i can)

I agree. couldn't have put it more succinctly myself. Having said that, 200 watts is barely going to move the bike on level ground, let alone powering it up the the most imperceptible incline.
Every time i ride my bike i know that at some point a police officer is going to do me good and proper and in Victoria (Australia), i'll be up for a minimum of $2,000 worth of fines when it happens; and it "will" happen - just a matter of time, but i enjoy riding my motorized bicycle more than what the fines are worth.

For that reason i need my engine to look as stealthy as possible (from the rear of the bike), which eliminates the option of fitting an expansion chamber.
 
I haven't seen one, but the kit likely includes flat restrictors that bolt on between the cylinder head and the manifolds (intake and exhaust). NASCAR uses a restrictor on the intake only (similar to an intake gasket that has a smaller opening than the engine port. I'm guessing the exhaust is also restricted on the Zbox to help maintain some torque production. Exhaust restriction can increase torque while reducing horsepower.
If you already have a gas engine, I would give the zbox restrictor a shot if suitable documentation is shipped with the kit to convince law enforcement of the engine performance (or lack thereof).
Otherwise, as much as I would like to know how well the Zbox 200W kit performs, I think you are probably better off with an electric kit in OZ.

You know for something that MIGHT get you out of trouble with the police depending on who you get, Alot of people dont have them
 
dont worry about it?

while my first engines where zbox, since finding identical motors for half the price, i havent been back.

sounds like a plain old baffle on both sides, and for $90, you could make the same thing with an old cordial bottle on the intake and a piece of steel with a hole drilled for the exhaust.

total cost, nothing...

and then...unless you act like a doodlebrain...cops just laugh.

got a helmet on? stopping at red lights? pushing it, unpowered through shopping centres? they couldnt care less.

doing 70 in a school zone, no helmet, facing on coming traffic, tellin the lil kiddies on iphones to open their eyes, all whilst being a known criminal element...just catch a bus.

i live rural. so one, its sort of a necessity when the license is taken, a hobby otherwise.

if you live in a built up area...start actually pedalling, or show some respect and go electric.

electric has the benefit of producing maximum TORQUE at low rpm. unlike petrol engines that need to run at a certain rpm for a certain torque output.


whats the difference?

they measure the OUTPUT power. power is torque per revolution per minute.

you can dump, say, 48 volts at 100 amp through a motor, while its shaft isnt turning...

thats 4800 watts on the INPUT. now that would make for a nasty electric bike!

but as the shaft isnt TURNING, the output power...is zero! at a complete standstill, anyways.

meanwhile...the torque is there, just trying to twist things into pretzels or move you...


once rotating, then the power input needs some moderating. you can still have gobs of torque at low rpm, and keep within output power.

at high rpm, torque has to obviously be reduced to keep within power restrictions by drastically reducing the current available to the motor.

problem is finding an electric motor and battery capable. and engineering a speed control with the appropriate circuitry. things like cars and planes in rc want smooth throttle control with max power at all rpm...

i notice the new version of one of my esc i tried finding the manual for, has a programmable governor. its only good for 300watt max.

its VERY EASY to intergrate a hall effect twist throttle via two 555's into an RC esc throttle. just pwm :)

um... oh!

just find a 250 amp ESC with governor function.


look at the SPECS!

7992 WATTS!!!!!


thats ten freakin horsies! and a very very small pony.

This is exactly my thinking, i know how useless an actual 200w would be (my cordless screwdriver has more for gods sake) but im willing to bet 90% of police officers have never seen an actual 200w kit so if i can fudge some documentation then im up with a chance of getting away with it

i always ride with a helmet on, and on dedicated bike lanes or bike paths as much as possible, i have lights on at night, and im always pedaling (my legs arent doing much most of the time though lol) but even so ive been pulled over once and the cop tried his best to do me, after arguing my case as politely as possible (with no real 'proof') for over half an hour i got away with it but i might not be so lucky next time
 
Yeah exactly that's what I'm thinking myself bobo. Cause when you do get these kits they come with a note of compliance sayin that they are legal. Now with saying that, if some copper is trying to fine as many people as they can to get more revenue, they aren't going to care what piece of paper says, they are going to give you a fine. But it can go the other way as soon as they see that paper they just say ok bye hop in their car and drive away so it mainly depends on who you get.
