The Design section of the Ninebot by Segway KickScooter E3 covers a range of physical and structural characteristics that define how the scooter is built and used. It is intended for adult riders rather than children, and it does not include a seat, meaning it is used in a standing position. The frame can be folded, which aids in portability and storage. At 17,500 g, the scooter stands 1,235 mm tall and measures 1,165 mm in width. Riding comfort is supported by suspension and 10-inch pneumatic tires, which help manage uneven surfaces. Both front and rear lights are fitted as standard, and the scooter carries an IPX5 water resistance rating, indicating it can withstand water spray from any direction. A dedicated smartphone app is available, and the unit does not have a seat.
The KickScooter E3 is powered by a single 800W motor — it does not use dual motors — and reaches a top speed of 25 km/h. It can handle inclines of up to 18 degrees, making it capable on moderately sloped terrain. Braking is handled by both a front and a rear brake, providing stopping control at either wheel. The scooter supports a maximum rider weight of 120 kg.
The E3 offers a maximum range of 45 km per charge, with a full recharge taking 7 hours. The battery is not removable, so charging must be done with the unit itself rather than swapping in a spare. A battery level indicator is included, allowing riders to keep track of remaining charge during use.
