It is necessary to take into account that many factors come into play in the speed, crossing, and range announced by the manufacturer. These include weather conditions (wind, temperature...), terrain (slope, uphill, downhill...), battery wear, conditioning, the person's weight, etc.
Speed and range tests are conducted with an individual weighing between 55 and 75 kilograms on average by the manufacturers (for information) in eco mode and at the lowest speed setting.
To ensure the proper functioning of your product and to avoid breakdowns or damage, it is recommended to carry out a full service every 600 km at least (see workshop recommendations) in addition to checks before each use. Sometimes certain chassis parts or moving elements need to be checked, adjusted, or even replaced, even if they appear to be in good condition.
Failure to follow the service schedule may result in the manufacturer refusing your warranty.
