Jimi Heselden, the owner of Segway, has died after riding one of the scooters off a cliff and into a river, according to reports. According to the BBC: Heselden, 61, died yesterday after crashing into the River Wharfe. The incident took place on his West Yorkshire estate and has thus far been deemed an accident. Segways are not legal to use on British roads and are restricted to use on private property. Heselden, who had already been an investor in the U.K. Segway dealership, bought the company at the end of 2009. The devices were launched in 2001 by inventor Dean Kamen, eliciting claims of revolutionizing transport at the time but ultimately failing to catch on beyond a niche base of tour groups and the wealthy.
