Beautiful device but not immediately user-friendly

- Dirk, 1 December, 2024

Personally, I don't find it an easy and handy device. Nice though and does what it should do if you don't use gps and other things

Pros & Cons

Large screen
Many options
Navigation
Not user-friendly
Sometimes gps signal disappears

Unable to commission

- Ha, 10 June, 2024

Unfortunately, I overlooked the fact that the computer, software programme and app are not compatible with ChromeOS (/Chromebook). Although available in the Google play store, the Sigma app does not appear to work properly with ChromeOS. On enquiry with Sigma, they confirmed this. With this, this bike computer loses part of its value for my intended purpose. So unfortunately it will be returned. Functioning itself therefore not assessed.

Not compatible with ChromeOS

Great entry for great price!

- Axl, 1 April, 2024

I bought it as an entry-level model to gauge to what extent a bike computer would add value and which functions are really necessary. After a while, it became clear what was missing for me personally. But it is a great starter model that nicely displays your performance and can introduce you to the data that comes into play during a bike ride.

Pros & Cons

Illuminated in the dark
In my eyes, does what it should for its price
Live tracking via komoot
Sufficient battery
Tabs to personalise
Average max speed often came out too high
Difficult to follow training schedules with it
Some manoeuvres are confusing with the tracknav
Track navigation only and no map view
