Getting your bike stolen sucks. Simply losing it can be even worse. While the odds of getting a stolen bike back are slim to none, there are steps you can take to make being reunited with your bike a bit more likely. The BikeGuard bicycle registration system is basically an inventory tool that allows you to attach your bike to a registration number, making it possible to be traced and thereby more likely to be returned.
The best part about BikeGuard, of course, is that it involves absolutely no cost to you at all. You simply register online, then BikeGuard will send you 3 tags connected to the bike registration number.
