what makes the InMotion S1 so popular with commuters is the smoothness of the ride. The acceleration is electronically filtered to provide the smoothest take-off and slow down on any electric scooter we have ever tested. So whether you are quickly accelerating up to the top speed of 30km/h or cruising along at a steady pace, you will never feel the InMotion S1 bounce you around. For riders who want to feel safe and have complete control over their scooter, this is a hugely important characteristic of riding the InMotion S1.
