Transcript: Past meets future. Rumble Motors has created an electric scooter with a built-in fake engine sound. According to Rumble, the noise of the engine provides a sense of warning to other motorists and pedestrians. The realistic motorcycle sound responds immediately to turning the throttle. It has a max speed of 44 mph with a 2,000 watt motor and can travel 60 miles per charge. It also includes a speedometer, low and high beams, and a battery display. The 72 volt battery can be fully charged in 2-3 hours. The Rumble electric scooter costs $3,490.
