Nylon Bike, anyone?

Titanium, carbon, aluminum, steel? Nope, Nylon is the future.

They can already get a bike frame down to 1.5 pounds using carbon fiber.. If that process can make a frame as light or lighter than that at a lower cost without sacrificing strength, then it will become more than a mere "novelty.."

methinks "novelty" is an understatement. This is clearly a PR stunt, and they've proven that they can make a bike-shaped thing.

Yep. It's more about the manufacturing process rather than building a better bike. Besides, plastic bikes have been tried: http://en.wikipedia.org/wiki/Plastic_bicycle

Its a neat technology demonstrator that they can take to trade shows and people can ride in small circles. More fun than looking at a fabricated widget and, with a pretty girl on, guaranteed to make a photo-op.

Ummm,,,,, I'd guess,,,,,, the plastic bicycle?

At 1:18 the video seemed to show the 3D printing machine making the ball bearings and bearing races, but says at 1:26 that the layers are made one-tenth of a mm at a time.... Which isn't nearly accurate enough to make any sort of bearings. Even the cheapest Chinese generic ball bearings and races are ground to tolerances down to around 1/100th of a mm--ten times as accurate.




I don't know anything about that particular company.
3-D printing is a hot buzzword and nifty to watch but isn't ever going to be a huge manufacturing process.
It's great for a prototyping or one-off (single customized item) manufacturing, but much too slow for mass production.

If you notice, it has a huge bottom bracket, so those bearings may be the size of marbles. The bike is clearly a pointless flub made by people knowing nothing about bicycles, it is the process that is the feature, and the reporters fail to realize the difference.

The nylon "as strong as steel" usually means that pound for pound, it is as strong as steel, which is to say, it requires a cross section considerably larger since the material is lighter.

That noise at the end scared me. I don't see why they didn't show him riding it anymore than they did. He even had to be pushed!

I wonder if anyone has ever made a glass bicycle.

Even MBA picked up on this; they called it "what mountain bikes are coming to in the future". Makes me want to slap either McIlvain or Cunningham.

A GLASS bicycle? Sure -- saw the prototype; was stiff as could be until the rider hit a crease in the pavement, and !@#$%^&*(!!

Tempered glass. He's still picking it out of his chest.
