A:Answer It goes 10mph easily either uphill, level, or downhill. Plenty fast enough for most, feels like 50mph. It could go plenty faster, but the Segway limits itself and automatically slows it’s accelerating, even downhill it wont overspeed on you. Much like its own cruise control. The App lets you set the speed based on your skill level. I even discovered this goes off road pretty well too if you wanted to explore other new areas. Perfect for dog walking effortlessly making walks a piece of cake and keep and up with your pet.Battery life is unbelievable
