The ES-4 is Shutter Precision's second E-bike light launch. It's designed to outshine car headlights. The free-form optic technology, specifically the fish-eye lens - a key trait of the 4 series, has been fine - tuned. Certified with StVZO regulation, it ensures the safety of both riders and other road users. Its light beam features a distinct cut - off line, which is crucial for StVZO approval and a signature of other SP lights. This small yet powerful light is perfect for E - bikes. As E - bikes let you ride faster and farther, having a high - quality lamp becomes essential. We, as a leading bicycle component producer, use advanced technology to offer cyclists safe, enjoyable, and user - friendly components.

Using the ES - 4 light on your E - bike is easy. Just mount it securely on your bike according to the included instructions. When you're ready to ride, turn it on and enjoy the bright, regulated light. Remember to check the StVZO regulation in your area to ensure compliance. For maintenance, keep the lens clean with a soft, dry cloth to maintain optimal light output. Avoid using harsh chemicals on the light.
