Using this bike is easy. Just hop on, adjust the seat to your comfort, and start pedaling. When you're riding on flat paths, use the middle gears for a smooth and efficient ride. On hills, shift to lower gears to make pedaling easier, and higher gears on downhills. When you need to stop, gently squeeze the V - brakes. For safety, always wear a helmet and follow traffic rules. When it comes to maintenance, keep the chain clean and lubricated regularly. Check the tire pressure every week and make sure it's at the recommended level. Also, periodically check the brakes to ensure they're working properly. If you notice any issues, it's best to take it to a professional bike mechanic.
