if u got a $25 bike buy a $25 GPS system.... otherwise invest in one thats actually gonna work wen u need it to. preferably one with cookies so u can track where it last went before losing the signal in an enclosed trailer, large apartment complex basement or storage area, warehouse, etc....
thieves will often dump a stolen bike in an apartment complex or hotel with ground floors and let it sit for a day or two to see if it has either GPS or Lojack tracking and monitor if anyone has come lookn for it. Lojack is far better cause its radio based and not effected by satellite reception. and GPS will only give u a general area. its not always specific. especially in a large apartment complex or housing project.
Lojack has the ability to use a hand held device so wen the signal is going off the police can take that device which will tell you exactly which apartment its located in cause its accurate to 5 feet away. but Lojack isn't available everywhere.
that 90% recovery rate is accurate with lojack. have never not found a vehicle with lojack when its goin off. its just a matter of time before the police hone in and either chase it or find it dumped near by. more often then not its found under a parking garage unoccupied. its a lot easier to hide a GPS or Lojack transmitter in a car then a bike but the Lojack transmitter has its own battery backup and battery last 10 years.
most MC thieves are quite experienced with how they work and how to take them apart. they will look for tracking devices sometimes cause their found naked often in the apartments wen tracing via Lojack. I have never recovered a stolen MC with anything other then Lojack. these MC thieves are no dummies just me. anything that loses a signal that easily by either disconnecting it and losing reception is not likely to be reliable and say bye-bye to ur bike.
