Using your Stubbie Pro Electric Bike is easy. First, make sure the Samsung battery is fully charged. Turn on the bike, and you can use the Pedal Assist (PAS) system to get extra power while pedaling. You can adjust the speed using the 7 - Speed Shimano transmission according to the terrain. For a smooth ride, adjust the suspension forks based on the surface you're riding on. When riding, always wear a helmet and follow traffic rules. Avoid overcharging the battery. After each ride, check the tires for any damage and keep them properly inflated. Regularly clean the bike to prevent dirt build - up. If you notice any issues, take it to a professional for maintenance.
