R4 GPS

READY TO GO ANY TIME!

The R4 GPS bike computer can be positioned directly on the handlebars in a few easy steps. There is no need to mount cables or sensors.

Your R4 GPS uses GPS and GLONASS to determine your position within a few seconds of being switched on.
The user-friendly operation with two buttons enables you to start a bike tour right away.
You can use the SIGMA RIDE app to set your individual display views.
