Thanks for confirming, zacster.

There's something with the V1 (Shimano rear hub) bikes that worked badly for me. One was the extra-low gearing. I think the other was the ergonomics, but I can't be sure.

The V2 bikes have SA rear hubs. I like them, and 3rd gear is high enough.

The V2.1 have Nuvinci hubs. I think the rear hub is the only difference from the V2 bikes.

So that leaves me liking (relatively) only the V2 bikes, and they are the rarest of all of them.
