Discover the ultimate cycling companion with the Hilceriy Cycle Computer! This multi-functional device tracks essential riding data including speed (average, maximum, km/h), distance, riding time, calories burned, and even temperature. Its compact, waterproof design is perfect for serious cyclists and fitness enthusiasts alike. Enjoy clear visibility day and night with an easy-to-activate backlight, ideal for dark paths or tunnels. Built to withstand rainstorms with IPX6 waterproofing, it ensures durability without compromising accuracy (note: temperature readings may reflect water temperature in heavy rain). The auto wake-up feature saves energy by entering sleep mode after 3 minutes of inactivity, and instantly resumes recording when you start cycling or touch the screen. Compatible with road, mountain, and folding bikes (excluding some electric-assist bikes), installation is simple with the included sensor and magnet.
