The top speed of Fliteboard depends on A) The wing used, B) The rider's weight and height, and C) The rider experience. In our testing an 80kg rider using the Flyer wing achieved a top speed of 40km/h. The same rider with the Cruiser wing can achieve a top speed of 34km/h. We expect these performance metrics to improve as we further refine wings, propulsion and propeller for final production.
