    • Nice bike computer at a nice price
Style: Computer Only
So far it is working nicely. It uploads tracks to the Sigma app, Strava and Komoot. I haven’t tried the navigation feature yet. The speed and track seem to be accurate and I had no trouble with the satellite connection. The temperature readout is way off, it’s not very important to me but would have been nice. It’s a good replacement for my old wired computer, with additional features and a reasonable price. ... show more

    • not intuitive
Style: Computer Only
Display is great, the mount fits a garmin 510 handlebar mount. Everything is good except it isnt intuitive. for example.: when you turn it on, it comes on and i start to ride. 3 minutes later it asks if you want to start training? Well duh! if you neglect it, it shuts down. also, i still havent figured out a foolproof way to shut it off. I know there is a way because occcassionally i see a question shutdown? but i havent figured out the majic.... come on sigma! ... show more

    • Glitchy software and now the display is frozen after 2 rides.
Style: Computer Only
The first ride I got six chimes alerting me that the unit lost GPS signal on a rural road no mountains or tall buildings to block the signal. Then it made a noise and shut down after about 20 miles of the ride. When I turned it back on the battery display still showed a full charge. When it prompted a firmware update I was hoping that would fix the software issues. Instead my phone said update failed and the unit is locked with update in process displayed. The clock froze as well and hasn't changed in the 12 hours since. It doesn't respond to any of the buttons and the phone can't connect to it. I'm hoping when the battery dies it may reset and be usable again. ... show more

    • Fantastic Computer
Style: Computer Only
This bike computer is fantastic. The case is plastic, but it seems very strong/robust. The buttons also seem very sturdy. I bought the model with the sensor kit and the clamp mount. The mount is very sturdy and very well made. It comes with a couple shims that make it fit a variety of bars. I very much like the clamp. The computer is a good large size that makes it easy to see and has a backlight. One very neat feature is the ability to be able to customize the views. You have about 6 different screens you can customize...you have 4 fields up at a time, plus the clock at the top. It has a compass, altitude, etc. The sensor kit comes with a speed sensor, a cadence sensor and a HR sensor. This bike computer is GPS and doesn't require the speed sensor, but I am glad to have them for instances if the GPS doesn't connect. The GPS function does not have maps on the device, but requires connection to a smartphone to use those features live...but can be downloaded later to another device...as this functionality isn't required. This device has a longer battery life than the equivalent Garmin device, which is a major plus. If I had to say a negative (which to some may not matter) it would be that in order to change the fields/customize the views you have to have the device connected to a smartphone/tablet...you cannot do this directly on the device. I would like to see that in a future firmware update as this device be fully functional without the use of a smartphone for those who don't want to add that complexity or don't have a phone. ... show more
