Bicycle Safety and Registration

The Naperville Police Department’s Community Education/Crime Prevention Unit reminds residents to lock up their bicycles and register the make, model and serial number of their bicycles with the Naperville Police. Annually, numerous bicycle thefts and recoveries are reported to the Naperville Police. Most bicycles are taken from an open or unlocked garage or from the owner’s driveway, front or side yard with the majority of the bicycles not registered. Only a few of the stolen bicycles recovered are matched to a stole bicycle report and returned to the owner. Many stolen bicycles are never reported to the Naperville police and most of the recovered bicycles cannot be matched to an owner resulting in 100-125 bicycles being auctioned at the Naperville Police auction each spring.  

Be a good neighbor and remind bike owners to secure their bicycles when they finish a ride, close their garage doors and most importantly register their bicycle with the Naperville Police Department’s Record Section.

Bicycle Safety Do’s and Don’ts

  • Bicycles should always be locked with a secure locking device. 
  • Each bicycle should be locked to an immovable object such as a lamp pole or bicycle rack in an open and well-lighted area.
  • Lock both wheels and the frame.
  • Invest in a good locking system that will secure both wheels and the frame.
  • Register the make/model and serial number with the Naperville police department - Bike Registration Form (PDF 3.8 MB).
  • Don’t lock your bicycle to small tree, aluminum or wooden post or chain link fence. These can be cut or broken.
  • Don’t lock a bicycle to itself (front wheel locked to the frame) a thief can simply carry it away.

 Invest in a Good Lock 

By purchasing a good lock that will secure both the frame and wheels to a bicycle rack, the owner is making an investment in protecting their bicycle. Many stolen bicycles are never reported or registered with the Naperville Police so the owner cannot be traced. As Naperville continues to expand the scenic bicycle trails throughout the City remember to bring a lock for even a short stop for a refreshment break.

  • A recommended bicycle locking device consists of a three foot length of 1/4 inch hardened chain together with a keyed type padlock of high quality having at least a 1/4 inch hardened shackle.
  • Although there is no bicycle lock or chain that cannot be defeated, the “U” shape locks have proven to be effective. 
  • A good padlock should have at least a 7/16 inch hardened alloy steel shackle. The word “hardened” should be stamped on the shackle.

Be a Safe Rider 

The Naperville Police Department reminds all bicyclists to obey all of the traffic signs and rules of the road required by law as they apply to bicycles, do not wear head sets while riding, maintain bicycles with proper air inflated in tires and “Don’t forget to wear a helmet for a safe and enjoyable ride!”
