I love it. The Seek 0 is OEM-equipped with an Alfine-8 IGH and I'm glad that is gone. And it's much more efficient than the detractors think (I'm a mechanical engineer so I had to run my own tests to confirm). People point to the added weight as another downside but I think being able to fine-tune gears and seamlessly shift between them whether I'm pedaling or not more than makes up for the weight penalty. I just got the automatic shifting system working on it and I can keep my cadence within a couple rpm of desired so I just get on the bike and go.
