Cadence-Sensing Rainproof Wireless Bike Computer

A purpose-built wireless cycling computer combining cadence measurement, rainproof durability, and instant-read LCD clarity. Its 2.5-inch screen uses electroluminescent backlighting for uniform, glare-free visibility in any condition. Physical dimensions are 75 x 50 mm (3 x 2 in); total package weight is ~148.3 g (5.2 oz). Housed in robust ABS plastic and certified IP65, it withstands persistent rain and road spray. Mounts securely to standard 28–31 mm (1.10–1.22 in) handlebars using the included bracket and cable ties. Powered by two built-in CR2032 batteries (210 mAh each), which are included and ready to use. The device supports a dual-bike system with independent trip timers, service reminders, and odometer storage for Bike 1 and Bike 2. Core metrics include current/maximum/average speed and cadence, trip and total distance, calories and fat burn estimates, ambient temperature (C/F selectable), digital clock (12/24 hr), KM/M unit choice, speed comparison, speed tendency display, and odometer save. Intelligent automation covers auto-start/stop, auto-wake-up, and auto power-off. Built for real-world UK cycling — from wet winter commutes to summer sportives — it prioritises functional integrity over flashy extras, offering trustworthy data without connectivity compromises or battery anxiety.
