Use the 60+ km/h catalogue filter to identify candidates, but treat speed as one part of a system. At higher speed, tyres, brakes, suspension, frame stiffness, lighting, rider protection and legal compliance become more important.
Questions to ask
Is the number peak or sustainable? At what battery state of charge? What tyres and brakes are fitted? Is the speed road-legal for your use? Is there a trained service centre? A fast scooter with weak support can create more risk and cost than value.
