I live in an apartment block where there are toast racks for bike storage. Useless wheelbender floor racks which you could cut with boltcutters. My two bikes are hanging from front wheels on wall mounted racks.
I have several chain locks and a U-lock securing them.
Short of getting proper ground anchors or Sheffield stands are there good ideas on security?
I would've thought that putting in a call to the partner of the late Doc Squid, formerly OTP, would be a good starting point. I've spoken with him before and found him both affable and helpful. The company name is Pragmasis. His name is Stephen, and he was using DS's account on here shortly after her death, but it's a few years since he's been active on here.
My personal view is that max security for least buck would probably be in the shape of a floor anchor.
