I'm getting some deja vu. I swear this thing has been "available to order" for probably a year now and always with an estimated shipping date. Currently the site says "funding" and the "campaign" ends in 29 days, it's sounding like something off Kickstarter and we know how a lot of those projects go. Also if you reload the product page you can catch this. Of course they're past that date now, but if that's what they needed and what they've got then I don't think another month is going to net them $54m.
It's a shame because it sounds like a great bike at a cracking price, but likely just another case of too good to be true.
