The Sigma BC1609 Cadence bike computer is a well-designed bike computer that records 11 different functions. The screen is the same size and shape as the Sigma 1009, making it very visible on the fly. It was reliable and durable during our testing, but takes a dedicated effort to attach to a bike. It isn't a computer you want to switch around on a regular basis.
The Sigma 1609 provides cadence and stopwatch functions that our Best Buy winner, the Cateye CC-RD300W Strada Wireless Bike Computer, does not, but is hindered by the lengthy set-up and wires necessary for the sensors. Even though the 1609 offers these extra perks, it scores below our Top Pick winner, the STRAVA app, and also well below the Editors' Choice Garmin Edge 810 in terms of features.
A good alternative would be the wireless version of this computer. The Sigma BC1609 Double Wireless Bicycle Speedometer is $94.99, and offers the same functionality without the wires.
