Brisbane's MASSIVE underground tunnel system...

I call this URBEXMTB... Urban Exploration on MTB. I still can't believe I could ride my bike in here! The flashlights I usually use for tunnel explorations: Wurkkos HD50 4000 Lms: https://amzn.to/444gUFq Fenix HM61R V2.0 1600 Lms: https://amzn.to/3GBJC6I Both are amazing lighting systems and have red lights integrated!
