I am sure this is a common issue and/or has been discussed before so point me to the right place if it has.

Since I started riding a bike regularly again I released that I do not trigger the lights or the gates into apartment complexes (even with a transponder) .

I have asked the company who operate the gates and they believe that bikes do not get picked up as they are not magnetic enough rather than heavy enough.

I live in southern California if that makes any difference.

Anyone else have the same problem? Any solutions?
