Using your E-Rider City Wave electric bike is a piece of cake. Just hop on, adjust the handlebar if needed, and start pedaling. The upright riding position makes it easy to control. When you're in the city and need to stop frequently, the low center of gravity keeps you stable. For charging, find a standard power outlet and plug in the charger to the 375wh battery. As for maintenance, keep the bike clean by washing it regularly with a mild soap and water. Check the tire pressure often, especially before long rides. Make sure the brakes are working properly, and lubricate the chain every few weeks. If you notice any issues, take it to a professional bike mechanic. Also, don't leave the bike in extreme weather conditions for a long time to protect its components.
