COBI.Bike doesn't support ANT+ yet.
When logging a pedelec ride with COBI.Bike, an ANT+ heart rate (e.g. Garmin vívosport) and temperature (e.g. Garmin tempe) sensor, either only Power and Cadence are visible in Strava when uploading the track data with COBI.Bike:

With CombineGPX, you can augment the COBI.Bike GPX export with the Heart Rate data GPX export(s) and Temperature FIT export logged with e.g. myWorkouts:

It also outputs some pretty SVG:

Requires Java 9 or newer.

Usage: Double click .jar or java -jar CombineGPX.jar [cobi.gpx hr.gpx [hr2.gpx …] []]

Tip: When §@#! COBI.Bike once again didn't upload track data, choose Connect export twice and replace ns3 with gpxtpx.
