I had a Labral tear repair done in 2016 (followed by a clean up to wave post op frozen shoulder). Don’t think I was allowed outside on a bike for at least 3 months post op
Most important is engage a good private physio with lots of shoulder expertise for as soon as the surgeon clears you. Well worth it to avoid post op complications (NHS physio can be sorely lacking for ongoing post op rehab, last NHS physio wanted to see me every 3 weeks, shame I could get a slot more than every 6!)
This forum although US centric is good for shoulder surgery patient experiences

When’s the surgery?
