This really does sound like a product since bikes can cost these days.

a 1 inch square solar panel. Solar panels made of flexible film exist,
but are not robust. They'll get better.

Instead of relying on GPS, another tactic discussed so far was to monitor
closeness
to various safe zones, where it can communicate with a base station. Then the
task becomes decide when to alarm and contact the cell phone towers. Trying to
contact
and getting no signal could be quick and a low power drain. Without
communication
there would be no need to go into mode 3. get a GPS fix, (or not), and send
status
to a phone number. If GPS was unavailable, it might be possible to track by
phone calls
to the bike, if the cell phone company cooperated, i.e. after police were
involved.
