Overview

The Sigma Sport BC 5.16 is a wireless bike computer stripped down to the essentials. It displays current speed, trip distance, total distance, ride time, and a clock — the five core metrics that everyday cyclists actually check during a ride. The wireless sensor transmits data from the front wheel to the handlebar-mounted head unit without any cable routing, keeping your bike looking clean and simplifying installation. The tool-free mount lets you attach the computer to your handlebars in minutes and remove it just as quickly when locking up.

Durability is a strong point, with an IPX8 water resistance rating that goes beyond splash protection — the unit is rated for continuous submersion, so riding through heavy downpours or hosing down your bike after a muddy ride is not a concern. The compact form factor sits unobtrusively on the bars and presents data on a clear display designed for quick mid-ride glances. The BC 5.16 is intentionally simple: it does not attempt to replace a GPS unit or fitness tracker, but instead provides reliable, real-time cycling data for commuters, casual riders, and anyone who values straightforward functionality over feature overload.
