Sigma was founded in Germany in 1981 and specialises in bicycle computers, lighting systems and electronic accessories. The company name comes from the Greek letter Sigma, which is often used in mathematics and technology as a symbol for a sum or a totality. This choice of name was intended to convey technical precision and a systematic approach. Since its foundation the company has grown steadily and today offers a broad range of electronic components for cycling. Sigma has established a firm place in both the German and international bicycle accessory market over the decades.
The first Sigma products were mechanical bicycle speedometers that could measure speed and distance travelled. Over time the company expanded its range to include digital bicycle computers with ever more functions such as altimetry, heart rate monitoring and GPS. LED lighting systems for front and rear lights were added later. Today Sigma produces not only classic bicycle computers but also modern lighting solutions that rely on USB charging and offer different brightness levels.
Sigma products are sold in specialist bicycle shops, online stores and large sports chains in many countries. The exact number of sales outlets is in the low four-figure range across Europe. In Germany Sigma has a particularly strong presence thanks to close relationships with specialist retailers. Distribution takes place both through stationary shops and through numerous internet platforms.
Among the products on offer a choice can be made between individual lights and complete sets. The front lights differ in brightness, ranging from 35 to 80 lux, while the rear lights come in different designs such as Nugget, Blaze or Infinity. The sets combine a front light with a matching rear light and are often more affordable than buying each item separately. All models use LED technology and are charged via USB cable.
