I don’t lock my bike when it’s in the shed, but this shed is brick, not wood. Currently waiting for delivery of ground anchors and some flexi locks to lock the bike into the floor for when i’m not about.
As for locking the bike up, i never lock my road bike up at work, just leave it in the bike stands outside of reception. (But it’s a secure site with records of who is on site, tag in and out of every room etc, so security is high). When i ride my mtb to work though, that gets locked.
Only time lock my bike up is outside of shops, or when i’m leaving my bike on the back of the car when i’m in a shop or someones house etc.
