Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
In the pic with the designer/builder, his right hand looks monstrous for his body size. Photoshop job?
Also, I don't see how it could go from the folded configuration to the fully extended configuration without it coming apart into two pieces.
In the folded configuration picture, looks like the hinge point on the frame is the front sprocket. But in the fully extended configuration, there's nothing connected to the front sprocket at all.
In addition, it is coming out of North Vietnam. Sorry, but folks in North Vietnam are literally starving to death...I highly doubt a student was able to source high-tech components like this from nearby suppliers, let alone pay for them or even get them for free. My guess is all the people mentioned in the article that helped him out would be spending most of their time looking for food, not building uber-tech electric vehicles in students' living rooms.
