SUMMARY
To achieve a speed of 32 km/h with a total weight of 90 kg using a direct drive system on an electric longboard, a brushless motor with a power rating of approximately 250 watts is recommended for smooth terrain. This estimate accounts for the combined weight of the longboard, battery, electronics, and rider. For uphill or rough terrain, higher wattage may be necessary to maintain speed. Reference tools such as the speed calculator from Kreuzotter can provide additional insights into power requirements based on terrain conditions.
