Registering a bike in the USA
 

Is it difficult to register a bike in the USA if purchased out of the country? Any and al help appreciated.

Registering Your Bike
 

Unfortunately, Chicago has a little bit of a reputation for having a high occurrence of bike theft. And if you're visiting this Web site, there's probably a good chance that you're one of those people who has a little bit of a sentimental attachment to your two-wheel wonder. Registering your bike with the Chicago Police Department is one of the easiest things you can do to increase the chances of getting your bike back after it's stolen.
