I also cycle to work a lot.
The strava2hive app has the possibility tonpost in the Cycling Community.
I haven't had contact with the Actifit crew about possible synergies, so I don't know if they would be open for that.

The Cycling Community isn't only for posting activities though. You can post all cycling related blogs.
I just started a #MYBIKE initiative where cyclist can show their bike tot other members. Maybe you would like to join this initiative too.

Your following the cycling account, not the community by the way.
