I'm keying my comment off of Mr. Boutakis statement that "Our CNC partner is behind on delivering our 5-axis parts and this set us back this week." As a production engineer I look at the design and the price and see some trouble in the future. I believe the product has been somewhat undervalued. Helix may be able to deliver the bike at $2k but he will soon get tired of his tiny margins.

However, I love the unfolded design. I'm sure it would be possible to produce it sustainably at the $2k price point, with some simplification. My Bike Friday has an offset (diagonal) fold that allows the rear wheel to sit beside the frame with a lot of extra space (and dangling metal... typical of Bike Friday.) The Airnimal uses an orthogonal folding axis so the wheel hits the frame. Their design requires removing the front wheel to open that volume to the fold. If you merge the two approaches you should be able to produce a fold only a couple of inches sloppier than the Helix fold. It is as if the perfection of the Helix fold has become a fetish. But I think it is a fetish worth $4000.
