Cycling is amazing. It’s what drives us, what excites us. But part of the experience is sharing the road with others—cars, trucks, motorcycles, and fellow cyclists. That’s just the reality of it. With this in mind, Cannondale introduced SmartSense in 2022—the first fully integrated and connected system of on-bike lights, radar, and sensors. By linking the lights with radar, SmartSense increases visibility and awareness on the road. And thanks to its seamless integration and single-battery power source, the system is incredibly easy to use, making every ride more convenient and rider-friendly. It was a major step forward in enhancing the cycling experience for both riders and other road users.

Now, with the launch of the 2025 Cannondale Synapse Carbon, we’re taking SmartSense to the next level with its 2nd generation—building on its groundbreaking foundation to enhance safety, convenience, and performance even further.
