Fine bike computer with great price/performance ratio!

- Michiel 30 July 2025

Fine bike computer with lots of features. I had a Gramin Edge 100 before and could never find the right setting in the menus. For the Sigma, I haven't needed the manual once!

Pros & Cons

direct link to Komoot
ease of use
price/performance ratio
relatively long start-up time
Automatic translation

Fine and simple bicycle navigation meets my expectations!

- Gert Jan 6 November 2024

Great bike navigation easy to use on my road bike and e-bike thanks to the two supplied mounting brackets. In the beginning it was a bit difficult to transfer cycling routes via Komoot but now it goes quite well. Tip: set everything properly at home before cycling and not while cycling for your own safety and for other road users!

Pros & Cons

Can be used on two bikes
Excellent bicycle navigation
Simple to use
Additional purchase Komoot maps.

5 / 5

Top purchase considering the price-to-product ratio

- Huub 9 September 2024

Within a short time you have mastered the controls. Compared to my older Garmin, the ease of use is many times better.

Pros & Cons

Fine screen with clear map image and info
Reasonably priced compared to other brands
Simple operation with logical structure

Big disappointment!

- Sylvain 7 September 2024

This is the brand's top-of-the-range meter, but it's much less reliable than lower-range meters!
