Riding an electric scooter in the rain can be safe, but it depends on several factors. The waterproof rating of the scooter, indicated by the IP (Ingress Protection) code, determines its ability to withstand rain. Scooters with IPX4 to IPX6 ratings are suitable for light to moderate rain, but submersion or heavy downpours should be avoided. Additionally, tire tread and traction are crucial for grip on wet surfaces, and the scooter's battery and electrical components should be well-protected from water to prevent damage. Always consider safety precautions and local laws before riding in the rain.
