OK, so AFAIK, Vicroad requires any motorised vehicle, including 50cc, registed; unless the vehicle produces less than 200W (which is f**k all). That means paying the registration + TAC each year and the vehicle requires a number plate, right? More or less, it falls under scooter category. What about getting an engine like ZBOX and stick it on your push bike? Even if I wanna do the right thing, I cannot registed my 'push bike with an engine' anyway, right? They have to be compliance with ADRs and Vicroad legislations... I'm thinking of 'motorise' my flat bar 700c road bike with a Zbox and only use it for commuting to work (20 kms round trip). At the same time, I'll be saving up for a 'good' motorbike and use it as my main vehicle. Btw, I can cycle to work (have done it before) but it's not easy accessing to shower facility at the moment.
