Where to buy new Fat Bikes in Perth?

Trying to find fat bike recommendations is frustrating!

I'm having trouble finding a good place to source a fat (4-5" tyre) bike in Perth. My trouble is that there are helpful online reviews for mainline fat bikes, but these never seem to cover
a) electric fat bikes, or
b) other brands or brands that are new to the market (which seems to be the only fatbikes - bar Diamant - that get an electric conversion)

Every bike shop only seems to sell a very restricted range of fatbikes (especially when it comes to electric fat bikes) - often just one brand - and I've no way of telling whether they are just pushing their product, or, more likely, know little about other brands.

I'm not totally sold on it being electric (though it seems like a good idea to extend range and usability), but I mainly want a very rugged, bush-worthy mountain bike with as fat tyres as possible. I'll be paying via eftpos so I guess that basically restricts me to new rather than the ocassional great 2nd hand deals I spot on gumtree. Also the frame needs to be large enough to suit my 6'3" height (plenty of local shops don't even have any XL frames...).

Is there a review source that covers the types of brands available in Perth (eg. Overide's "Enduro"), or online in Australia? Or are these lesser-known brands not quality?

Can you recommend an online review site that has more than just a few brands and isn't dated 5+ years ago?

Or do you have specific recommendations regarding bikes? (some recommended fat bikes either aren't available in Australia, or come at a very different price point) Or even regarding shope stocking fatbikes?

Thanks for reading this far, and thanks in advance for any wisdom you can drop!
