What is the proper way to setup downhill biking with lifts activity?

You could use the MTB Activity, pausing it while you are on the lift.

Thanks for the answer. To be hones I thought there is more sophisticated way, Because Ski-snowboard activity do this automatically or detect somehow when I am on a lift. However, inside Ski-snowboard activity I see no such option. Maybe it is somewhere in the config files, idk.

Recording Ski-snb and then converting it to cycling seems not a proper way too.

Not sure how the Snowboard Activity detects the lift, but you can try using the auto-pause function, perhaps it does the same. If not, create a custom activity based on the Snowboard. You will still need to assign Cycling to it in GC, since it won't be categorized as cycling automatically.

Thanks, will give it a try
