Using your Razor Power Core S150 Red electric scooter is easy. First, start by giving it a good kick to activate the motor. Then, press the thumb - activated throttle to start moving and control your speed. When you need to stop, use the hand - operated front brake and the rear fender brake. Make sure you're at least 13 years old and don't exceed the maximum rider weight of 154 lbs (70 kg). For maintenance, keep the scooter clean, especially the tires and brakes. Check the battery regularly and recharge it using the included charger after each use. Since the motor is maintenance - free, you don't have to worry about alignment, chain, or belt issues. Store the scooter in a dry place to avoid rusting the steel frame and parts.
