Horrible video. The website is even worse. It prompted a cranky Comment from me at YouTube:
Very unhelpful video and unhelpful website. What are the complete specs? They’re nowhere to be found! Top speed? Max range? Weight? Battery type? Battery brand? Truck size? Wheel diameter and durometer? These are the things that matter, not some Germans swanning around on it.
If they can’t even get the basics sorted out, how bad must that board itself be?
