I have one for my sportbike. It has a lanyard to use so you don't forget it's on before you go to ride. But you don't really need the lanyard because as soon as you stand the bike upright to sit on it the alarm goes off so loud it wakes the dead. That would be the best thing about it for a bicycle, it would basically be a very, very loud alarm. You could use it on a rim brake bike, just attach it to a spoke.
