Default Bell rings when garden gate opens?

My small city garden has a standard Victorian railing
on the street, with the gate as part of the railing.
A few days ago someone came in the garden and stole
a (locked) bike.

This made me wonder if there is any simple way
to make a bell ring when the gate is opened?

Also, is there a standard spring which will
keep the gate closed?
