Using the Turbo Vado SL 2 4.0 e - bike is easy. First, turn on the power switch located near the handlebars. Then, adjust the pedal - assist level according to your needs. You can choose a higher level for more power when going uphill or a lower level for a more natural ride on flat roads. When riding, keep your eyes on the road and follow traffic rules. For maintenance, regularly check the tire pressure to ensure a smooth ride. Also, clean the bike after each use, especially if you've ridden in muddy or wet conditions. Store the bike in a dry place to prevent rust. Charge the battery as needed, and don't let it completely discharge before recharging. If you notice any issues, take it to a professional bike mechanic.
