I found a picture of  the finished custom trike that i made the seat for......now those are BIG WHEELS!!!!!

Trike made by http://www.gworkscustomcycles.com.au/

 

that is wide!

FFS! A decent revving and you'd be on your back trying to prise the fuel tank off your crotch! Imagine the stones will flick up

I would say it's still a 'work in progress'. Does not look like it is registered and doubt that it could be registered without guards over the wheels

 

nice though...
