Take your rides to the next level with the iGPSPORT BSC300 GPS Bike Computer. This isn't just a speedometer – it's your personal riding assistant packed with features. The star of the show is the OFFLINE MAP navigation. Download maps to the device, load a route, and get turn-by-turn prompts so you can explore new areas without getting lost. It even has an 'off course' warning to nudge you back on track. It tracks over 130 different data points – speed, distance, elevation, cadence, heart rate (with sensor), calories, temperature, and way more. It connects to almost everything via ANT+ and Bluetooth 5.0: speed sensors, cadence sensors, heart rate monitors, radar lights, and even your Insta360 camera. For group rides, the Live Track function lets teammates see your real-time location on the map. It uses 5 satellite systems (GPS, Beidou, GLONASS, Galileo, QZSS) for fast, super-accurate positioning anywhere. The screen is clear, it's IPX7 waterproof (rain is no problem), and it syncs with apps like iGPSPORT, Strava, and Komoot to analyze and share your rides. Whether you're road cycling, mountain biking, touring, or racing, the BSC300 gives you the data and guidance to ride better.
