Using the Merida eSpresso 400 S EQ is easy. First, make sure the battery is charged. Then, turn on the power and start pedaling. The electric assist will kick in to make your ride smoother. When you're riding, use the Shimano Hydraulic Disc Brakes to stop safely in any weather. The Suntour NEX front fork will help you handle bumps on the road. Remember to keep your eyes on the road and follow traffic rules. For maintenance, check the tire pressure regularly, especially the Continental Ride Cruiser Tyres with puncture protection. Clean the bike after each ride to remove dirt and debris. If you're not using the bike for a long time, store it in a dry place. And don't forget to lock it with the Abus 5650 frame lock when you park.
