Our thumb drive models have a top-speed control knob and the Dream has a turtle and rabbit top-speed switch. In rabbit mode your scooter can reach a max speed of about 4.4 mph (7.0 km/h). Always ensure you are in turtle mode while moving on or off transportation, navigating through crowds and/or near any uneven surfaces or curbs for safety. As the rider you directly control your scooter’s top speed by the lever, similar to how hard you press on the gas pedal of a car.
