It is necessary to take into account that in the speed, crossing, and autonomy announced by the manufacturer, many factors come into play. These include weather conditions (wind, temperature...), terrain (slope, ascent, descent...), battery wear, conditioning, the person's weight, etc.
Speed and autonomy tests are conducted with an individual whose weight varies 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 avoid breakdowns or damage, it is recommended to perform a complete 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.
Without adherence to the maintenance schedule, the warranty may be refused by the manufacturer.
