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 Department.

Numerous bicycle thefts and recoveries are reported each year, with most bicycles taken from an open or unlocked garage or from the owner’s driveway, front or side yard. The majority of the bicycles are not registered, which results in only a few recovered bicycles being matched to a stolen bicycle report and returned to the owner. 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. 

Register your bike

To register your bike, simply return a completed Bike Registration Form (PDF) and a $1.00 fee to the Naperville Police Department, 1350 Aurora Avenue.

Bicycle Safety

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!”

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.  

  • Invest in a good locking system that will secure both wheels and the frame.
  • Each bicycle should be locked to an immovable object such as a lamp pole or bicycle rack in an open and well-lit area.
  • 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.
  • 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 7/16-inch hardened alloy steel shackle. The word “hardened” should be stamped on the shackle.
  • Although there is no bicycle lock or chain that cannot be defeated, the “U” shape locks have proven to be effective.
