FR is designed to withstand a droptest of 80cm (iirc) to concrete. There are 
no moveable parts inside except battery (which might be a good idea to add a 
*thin* layer of foam to fix it for good) and vibrator (and speaker 
membranes).
I don't think bicycle vibrations / impact is a big issue.

Nevertheless care about proper protection against rain or put FR in a pocket 
on first drop. Water resistance wasn't a design parameter.
