If you have a couple mile commute (say, to the train station) with a couple miles at the other end, something like this might be perfect. I'd rather see these electronic gizmos than cars...
One advantage of either the text file (I'd save it in CSV format as bla.csv.txt) or Google spreadsheets over image is that people can easily load your numbers and play with them.
I'd love to try one. I can (or, at least, I could) ride a unicycle, so I should take to it pretty easy.
If it folded up smaller, I could see it being useful getting to/from train-station, etc. (I use 16" folding bike now).
Crank length is a very personal thing. I agree that there are standard sizes for a given leg length, but if you are used to riding something different, that's just what you might prefer...
I believe you are correct on both accounts. I think MBB bikes will handle a front cover better than RWB bikes, but a front cover in wind is going to make things dicey regardless.
Learning to ride with one hand is a great idea. Learning to ride with no hands isn't a useful skill in itself (or, at least, it's arguable), but being able to do so means that you've really mastered the MBBB (Moving Bottom Bracket Beast - copyright 2015 - all rights reserved).
You haven't...
You'd have to build a special conversion kit for the beast. The issue is that you need to have a fork that can use the disc brake as it doesn't look like a rim brake could be used. If you can get/make a fork wide enough, the rest can fall into place.
Just think about how much fun that would...
The kid version of this has 20" wheels, gears, and is just begging for somebody to build a custom Cruzbike conversion kit that can handle fat tires. It would be Glorious!
Just sayin'...
Sorry about the fall. Been there.
Most front derailleurs are terribly under-specked. The original derailleur that came with my Sofrider and the 48/34 works beautifully with my 48/38/22. After you get your new derailleur setup, see how much room you have and consider dropping the granny gear...
