OK, after seeing this one-off custom bike from Kaos Custom Bikes in Australia, we’re agreeing with the comments on that other 36er from Eurobike that isn’t really a 36er.
Dubbed Zelda, Kaos made this bicycle using 36″ unicycle tires and rims built on Hope hubs with modified SRAM cassette and cranks.  They used bolt-in car tire valves and Stan’s NoTubes sealant to make them tubeless, saving 600g on tube weight.  It uses downhill Hope M4 disc brake rotors with Avid Elixir 5 brakes.
