I've been mostly into vintage bikes for aesthetics and bang for buck ride quality, so I've never really been one to keep up on new bike tech and the latest trends, but my brother sent me something that I think is rad as all hell, but I can see some obvious drawbacks and was interested to see what the community has to say about it.

The bike company is Classified bikes and their powershift rear hub claim to be able to change the output gear ratio electronically, thus creating a second set of ratios for your cassette like having a 2x drivetrain.

No bikes currently in their store, and no dealers west of Spain, but with the popularity of 1x systems, I'm curious if this will actually be a game changer. Thoughts?
