Not sure this would work
I hate to besmirch the Zak. But where's the circuit for this to work? The metal bar is one electrode but to whence would the juice flow from it through the victim?

Do your bike molesters take off their shoes and socks and obligingly stand on the un-rolled tin-foil that you have placed around your bike?

This was about 20 years ago (yipes!!)
so the exact method is hazy but, from how I remember it, there was some sort of capacitor in the box that stored the charge ready to unleash. All I had to do was connect the device (with wire / jumper-cable clip things) to something metal I wanted to be "live".

I can assure you, it did work (without the need for obliging victims - I guess the same way electric fences work without the need to wrap your cattle in foil.)

I must enter a subject
Yup - you'd defo need a capacitor and some form of step-up device for the voltage would probably help too.
