Here's KHE's explanation (which can be found by following the link above): "We'll build up a bike with all the lightweight parts we can find in our warehouse to see how far we can push the limits. How light can a serious bike become? You can check out the bike at the next Eurobike for sure."
Interesting. Stupid, but interesting. Look, titanium is a great material to make bike frames from. According to roadies and hardtail MTB types, it has a ride quality that can't be duplicated with steel or aluminum or carbon fiber. It's lightweight, corrosion-resistant, and super resilient. Of course it's also difficult to work with (just ask Eastern) and expensive as hell, which is how you wind up with things like a $3,200 road frame and a $9,000 commuter bike. Companies offer cheaper titanium, but you run the risk of getting a frame made from melted-down MIGs and old Chernobyl core rods.
BMX bikes, though? Not so much. Taj had someone fabricate a titanium Barcode and he hated it because it was so flexy (scroll about 2/3 of the way down). And you don't see those ti Grim Reapers advertised in Dan's anymore.
And I love that KHE asks "how far we can push the limits," like they may find some magical parts in their warehouse that will allow them to build a six-pound complete bike. If the ti frame weighs 2.16 pounds, and their top-of-the-line complete flat bike weighs in at 17.2 pounds (and costs $1,900), a complete built with the ti frame should weigh roughly two pounds less than that. That is, unless they decide to drill a bunch of holes in everything just to show off and make it even less rideable than it is already.
Which leads one to ponder, what exactly constitutes a serious bike? Flatland bikes may not have to stand up to 20-stair drops to flat, but they take a lot of abuse that a "regular" BMX bike never will, being pulled and spun and tweaked in multiple directions at once. Don't believe me? Check out this bike I shot at a jam this summer:
So even if you could build a 15-pound flatland bike (that would retail for roughly $3,000, of course), what's the point if it would just twist up like a pretzel the second a serious rider put it through its paces? Why not try and make a lightweight frame out of aluminum (already been done, I know) or some sort of carbon composite? Titanium? We've been down that road before. It's going to be light. It's going to be expensive. And it's going to suck.
And now for something completely different.
