5 / 5

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.

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!

Fine complete device with strong navigation and good price-quality

- Arno 29 July 2024

Fine complete device, with strong navigation;various options, easy with Komoot and fast. Price-quality is top. Battery life generously a day. The touchscreen makes operation easier than competing devices that do not have it. In addition, the price is friendlier than US competitors.
