TechCrunch's Disrupt Europe conference included new transportation concepts. The Moia electric van claims it's the world's first vehicle designed specifically for ride sharing. The battery-powered van will seat six passengers and rides will be booked using an app. The Stark electric skateboard has a top speed of 32 km/h and range of 19 kilometers per charge. Rubbee's clip-on electric engine, which can turn any bike into an e-bike, was also shown at the conference.
