Reminds me of the Hummingbird in concept.

I think the packing into backpack is meant for more extended times when you can't have the full bike with you, such as shopping and traveling. For commuting, I would be inclined to just fold the rear and stand it vertically to reduce footprint.

I would be interested to see how compactly one could pack this. Perhaps it could be a possibility for cabin luggage by also removing the rear wheel. A backpack might attract less attention when stepping up to a cabin gate.

Quite a steep price, I think. I like it, but I don't see one in my future garage.
