In this study of electrically powered small commuter scooters, we focused on short distance urban travel, and set a practical cruising distance. A high energy density Ni-MH battery, power unit module with inverter, and a motor with single gear reduction were selected to ensure necessary drive power with compact size and lightweight. The parts layout was optimized with consideration of front axle weight, to provide good handling and stability while reducing vehicle size. Lower seat height and a narrower floor enhances handling and the user's ability to touch the ground, while keeping the riding posture the same as that on a basic scooter. A lever type accelerator was used to enhance the operation of this scooter. As a result of the systems selected, this electrically powered small scooter combines clean, quiet, and smooth-operation with practical handling and stability performance. This flat floor scooter with its 1285 mm length, 44 kg mass, and 15 km cruising distance is easily handled even by novice riders.
