Nice to see another kiwi here mate!
“I could put a shaft in it” cracked me up.
Ive had eyes on a not hugely dissimilar design for a while, but im no suspension designer and despite some playing about in linkage, im scared of the rear brake. How are your rear braking forces looking? Are you Worried?
There’s a few of us around….. turns out there’s a few bikes that look the same (most are NZ too), look up Caeli in Linkage for some fun file names. I’m focusing on the drive side for now, I’ll tell ya in a few months lol
Never seen that done with a belt, but hey, there’s a first for everything 
Jut be aware that, contrary to a chain, a belt needs quite a lot of preload in order to not skip teeth! And in the case of a full sus frame, that preload exclusively comes from the tensioning device…
Perfect, I’ll add some more beef and fun stuff, yep tensioner will be fun, the G3 uses something similar doesn’t it?
Imo gearboxes with chains just make so much more sense to me. Easier to tension, more aftermarket support and when you remove it, you only need to break the chain, not the frame.
Yeah I’ll be honest I can endlessly battle with myself on chain vs belt, which is why I’ve gone into my own butt about it
Also without the cassette in the back you don’t have the cross chaining and they should last for a very long time.
Chain IMO
Beautiful!
