Please notice the scooter can travel a distance of 28km on a fully charged battery in ideal conditions. The following
are some of the major factors that will affect the operating range of your scooter.
TERRAIN: A smooth, flat surface will increase your driving distance, while driving uphill, as well as rough or uneven
terrain will reduce your distance significantly.
WEIGHT: The weight of the user can affect driving distance, a lighter user will have further range than a heavier
user.
AMBIENT TEMPERATURE: Please ride and store the scoooter under recommended temperatures, which will
increase driving distance, battery life, and overall performance of your scooter.
MAINTENANCE: Reasonable battery charging and maintenance will increase the distance. Overcharging the
battery can reduce range.
SPEED AND DRIVING STYLE: Maintaining a moderate speed will increase your distance; while travelling at high
speeds for extended periods, frequent starts, stop, idling, along with frequent acceleration and deceleration will
reduce your overall distance.
