I think the swap feature is nice. However, it doesn't "look" like the outer shell of the swap is very durable. Also, can the hub have a lower ratio than the Rohloff. I "think" the current gives it something like 16.5" using a 700c wheel. Can it go lower? I actually prefer less range and a lower low. When touring, or even club riding, I very rarely go over 20mph so for me a high of low to mid 80" is perfectly fine. I have multiple Rohloff wheels (multipe bikes), and I really wish it had less spread.

Neat concept, I would look at the finished product after a year or so it has actually been on the market.
