That one really hurting my eyes, what a pile. As far as a concept bike they have everything going on but in the wrong direction. Nobody wants a gear box or a floppy belt drive that may tighten up under sag. Then they stick the rear brake caliper where the rear derailer usually smashes into everything. Good luck at sea otter, might just end up ride that thing in to the sea.

 The plan of the gearbox was to remove vulnerable parts from the rear aka the derreilieur but then they decide to mount the rear brake there instead!

 What's biking gunna have next ,,,, heat seeking missiles nice but the mud will get in it easy

 put the brake on the inside of the rear triangle looks easy enough..
