All pocket bikes run a centrifugal clutch, suppose that could sound complicated for a beginner so consider it an automatic single-gear bike. Haven't heard much from Canberra at all unfortunatly, as Tz said someone will know. Good luck with your new bike, they require a lot of maintenance and small modifications to get them running smooth and reliable so I hope you've got the commitment
Edit: Turns out there was once a club in ACT but it seems to have shut down. Here's the link to the ACT rider's page anyway. You can read all about your local riders and such there.
