This varies depending on the rider's weight, terrain and slope. On a good flat road/footpath the 2-motor electric longboard, the TranceBoard (Lofty Ambition) can reach speeds of 45 km per hour (28 mph). However the boards are not only about speed but also more-so about carving and cruising. It's so much fun, you need to try it out. The Single Motor TranceBoard can reach a velocity of up to 33 km/h (21 mph), which is more than enough in our point of view.
