Maybe I missed somthing, but is it possible that you can't use Garmin segments on ebike-activity? I´m not talking about synced Strava segments. By the way...I do not want to start an discussion about Ebike segements. So please do not feel triggered.
I fully understand that activities for ebike and normal bike will be seperated.
Maybe it would be possible to use the same segments and show an ebike an non ebike time via filter, similar to the "only me filter".
But up to now it seems, that it´s not possible to create an new segment out of an ebike activity even
