I built that bike about 7 years ago. Except I know bikes, I know the proper angle for bullhorns, I know where to mount my brake levers, I know the basics of bike sizing. Some of the pictures I have seen on that site are scary. All looks, and no substance. I hope the product is better than their marketing. But the concept, a light single speed type urban bike, has worked out great for me - my bike does 25mph, for 25 miles and weighs 25lbs.
