Using the E - Rider Summit electric bike is easy. Just turn on the power, use the thumb throttle to get an electric assist, and enjoy your ride. When commuting or on the trails, remember to wear a helmet for safety. Also, check the brakes and tyres before each ride. For maintenance, keep the bike clean, especially after riding in muddy conditions. Lubricate the chain regularly to ensure smooth operation. Charge the 460wh battery as needed, but don't over - charge it. The one - year warranty covers most parts, but if you have any problems, contact our customer service.
