Using these brake levers is easy. Just install them onto the standard master cylinders of your 2018 - 2024 Sur - Ron Light Bee. When you ride, simply use your fingers to pull the levers to brake. Make sure your fingers are placed comfortably within the 35 - 45mm finger space. As for maintenance, keep the levers clean. You can use a soft cloth to wipe them regularly. Avoid using harsh chemicals as they might damage the orange anodised finish. Also, check the levers for any signs of wear or damage from time to time. If you notice anything wrong, it's best to replace them right away. And remember, since they are lightweight at only 61g, handle them with care during installation and use.
