There's no doubt that electric skateboards can get you around town in a hurry, but they don't hold a candle to this. Mischo Erban recently set a Guinness world record for the fastest speed on an e-skateboard, hitting 59.55MPH on NGV's four-motor NEXTboard as he blazed down a Slovenian runway. Was it dangerous to ride at highway-level speeds? You bet -- as you'll see in the video below, Erban took a tumble that could easily wreck an unprotected rider. Don't try this at home, folks.
