Sigma Rox 4.0 GPS bike computer (no sensors) 2023

Altitude measurement and intelligent navigation

The ROX 4.0 GPS supports you with its more than 30 functions and its user-friendliness on your bike tour, so that you can concentrate on the essentials: The fun of cycling. The extra large display reliably shows data such as altitude profile, speed, distance and training time. Navigation including re-routing function and the coupling to the e-bike as well as external sensors are a matter of course for the ROX 4.0 bike computer!

Search & GO
“Search & Go” navigation allows you to find a specific location and navigate there. You can enter an address into the SIGMA RIDE app on your smart phone or click on a point on the map. Trail preferences (bike trails, dirt roads, paved roads, and running/hiking trails) can be set individually. The track thus created can be started directly on your ROX 4.0 or saved in the RIDE app for later.

Re-routing and turn-by-turn directions
During navigation, the ROX 4.0 display shows the track and turn-by-turn directions. A turn arrow and audible signal alert you to the next turn. To make sure you don’t miss a turn, the Red Circle counts down the distance to the next turn using colored bars. They become less the closer you get to the turn. The ROX 4.0 also displays the street name. If you spontaneously deviate from the suggested route, your ROX plans a new route to the destination with a correspondingly updated elevation profile in a flash in interaction with the SIGMA RIDE app.

Tracks from third parties
The track navigation allows you to precisely ride a planned route. To do this, create a track in the SIGMA DATA CENTER or with a tour portal of your choice (komoot, Strava, etc.) and import it into the SIGMA RIDE app. You can then start your tour in the app and ride it right away or save it and start it later on your bike computer. This allows you to navigate your tour without a connection to your smart phone.

Ready to go any time!
The ROX 4.0 bike computer can be positioned directly on the handlebars in a few easy steps –entirely without cables or sensors. If you want, you can connect your Rox 4.0 to additional sensors for measuring speed, heart rate, and cadence.

Large display
The 2.4-inch-diagonal high-contrast display and extra-large numbers make it easy to read, even during a ride.

Red Circle
The innovative Red Circle on the upper right corner of the display is highlighted in various colours and offers innovative, interesting display of training data.

Everything at a glance
The SIGMA RIDE app allows you to set your display view individually. You can set up to six views, each with three values. Current speed and time are shown continuously on the display.

Up where the air is clear
A true highlight of the ROX 4.0 is the integrated air pressure sensor. It uses barometric readings to determine inclines and declines and provide you with reliable information about altitude, allowing a precise recording of your track. You can also call up a graphical altitude profile on the ROX 4.0. The home altitude at the beginning of the tour is determined automatically from GPS, or you can set altitude manually.

E-Bike-ready
You ride an e-bike? No problem. The ROX 4.0 is e-bike-ready and can be easily connected to many e-bikes. Your GPS bike computer establishes a connection to the compatible e-bike system and shows you the current assist mode, battery status, and light and other data on the display. You can use this list to find out if your E-BIKE is compatible with the ROX 4.0.

Best measurements
Do you need more data or even greater accuracy for your values? ANT+ and BLE enable you to connect external sensors such as speed, heart rate, and cadence sensors to your ROX 4.0. You can find accessories sets with various sensors for your ROX in our shop.

For data collectors
You can use the SIGMA RIDE app to collect your training data, transfer them to your smart phone via BLE, and quickly set your favourite display views on your smart phone. The most important data and statistics can be read from your smart phone in real time with the SIGMA RIDE app’s LIVE function and assessed conveniently.

Be there live
Record your data with your bike computer and analyse them right away with the SIGMA RIDE app’s LIVE view. You can set your individual display views extremely easily while you’re riding.

Stay tuned
Smart notifications connect you to the outside world even when you’re riding. Notifications of incoming calls and messages to your smart phone appear on your display.

Perfectly positioned
The Over Clamp Butler lets you align your ROX bike computer perfectly, even when using a short stem. The computer can be positioned directly over the stem, giving you more space on your handlebars and a clear view of all of your data, no matter what bike you’re riding. The Butler fits on 31.8mm and 35mm diameter handlebars.

Sigma GPS
The classical SIGMA GPS handlebar bracket can be fixed in place without tools in a few seconds with two cable ties. This gives you a choice between installation on your handlebars or on the stem, and the device fits handlebars of all sizes.
