Ok, that's pretty cool. Why not a gearbox though? Weight, maybe?
Presumable complexity and therefore cost and reliability, but given the simplicity and mature robustness of 2 and 3 speed hubs I'm a little surprised this is truly superior and worthwhile.
The problem is controlling the gearbox. In order to do that you need lots of parts from steel cables to crimps (that go on the ends of said cables) to derailleurs to levers and shifters and lots of other things to route the cables.
By only having two gears--and a simple mechanism to switch between them--this bike is able to avoid all that complexity. Not to mention the tools needed to repair said complexity.
A chain link remover is a tiny little thing that can be strapped (or taped) in a pouch and kept on the bike along with extra (tiny) chain links.
The thing they really need to work on next is the tubes. When I was really big into mountain biking I never had to repair my chain but I always carried two extra tubes (and a pump!) when riding because I had two flats on long rides more than once.
