ok swedish jerks: if youre considering the reliability and handling physics behind a moving object, it helps to be an engineer. yes, the bikes are fairly simple and yeah, its not a bridge but it moves and turns corners. its also made of metal. do you want to be traveling at 100 km/h on something that is made out of the wrong metal?
and no, the top of the line dudes arent engineers. they are artisans who come up with a design and farm out the work to other artisans. nothing wrong with that. im just saying.
