Most critical information

  1. 1. Serial number - #1 factor for recovery (80% don't know it)
  2. 2. Exact theft time/location - Within 2-hour window
  3. 3. Photos of bike - Including distinguishing features
  4. 4. Lock type - 59% of stolen bikes were locked
  5. 5. Proof of ownership - Any documentation showing it's yours

Walking into a police station unprepared wastes everyone's time and kills recovery chances. Police need specific information to enter your bike into databases, identify it if recovered, and prove ownership. Here's exactly what to gather before filing your report.

The serial number: Your bike's fingerprint

A serial number is the most reliable method for proving ownership and the easiest way for police to identify a stolen bike. Without it, your bike becomes virtually invisible in police databases.

Where to find your serial number

Most common location (70% of bikes)

Bottom bracket: Turn bike upside down, look where pedals attach to frame

Usually stamped into metal, 7-10 characters

Other locations to check

  • Head tube: Front of bike where handlebars attach (Rad Power, some Schwinn)
  • Rear dropout: Where rear wheel attaches (BMX bikes, older Schwinn)
  • Chain stays: Frame tubes running to rear wheel
  • Seat tube: Where seat post inserts
  • Down tube: May be on sticker underneath

Carbon frames: Often use stickers instead of stamping. Check all frame junctions.

Essential documentation checklist

Complete documentation checklist

Bike identification

  • Serial number (check all locations above)
  • Make & model (exact names, year if known)
  • Color scheme (primary/secondary colors)
  • Frame size (e.g., 56cm, Large, 19")
  • Type (road, mountain, hybrid, e-bike)
  • Value (purchase price & current estimate)

Visual documentation

  • Drive-side photo (right side showing gears)
  • Distinguishing features (stickers, damage, modifications)
  • Accessories (lights, computers, bags)
  • Component upgrades (custom parts)

Proof of ownership

  • Purchase receipt (store or online)
  • Credit card statement (showing purchase)
  • Service records (bike shop receipts)
  • Registration (Bike Index, 529 Garage)
  • Insurance documents (if covered)
  • Photos with bike (you as owner)

Theft circumstances information

Location and timing details

Exact location information

  • • Street address or intersection
  • • Type of location (home, business, public rack)
  • • Specific spot (front yard, bike room, street pole)
  • • Nearby landmarks or businesses
  • • Whether location has security cameras

Time window

  • • Last time you saw bike (date and time)
  • • When you discovered theft
  • • Narrowest possible time window

Security information

  • • Lock type and brand (U-lock, chain, cable)
  • • How bike was locked (frame only, frame + wheel)
  • • What bike was locked to
  • • Condition of lock remains (bring if possible)

Additional helpful information

Witnesses and surveillance

  • Names and contact info of anyone who saw theft
  • Nearby businesses that might have cameras
  • Building security or management contacts
  • Other theft victims from same location

Online marketplace evidence

If you've already spotted your bike online:

  • Screenshot of the listing
  • Copy the URL (https:// address)
  • Seller's username and contact info
  • Any communication with seller

Common problems and solutions

No serial number?

Without a serial number, recovery chances drop dramatically, but still report! Provide:

  • • Extremely detailed description of unique features
  • • Multiple photos from different angles
  • • Any custom modifications or damage
  • • Component serial numbers (wheels, groupset)
  • • Consider registering remaining bikes immediately

What police do with this information

Understanding how police use your information helps you provide better details:

  1. Database entry: Serial number entered into NCIC (National Crime Information Center)
  2. Pattern analysis: Location/time data identifies theft hotspots
  3. Recovery matching: Found bikes checked against database
  4. Prosecution evidence: Documentation proves ownership in court
  5. Insurance verification: Report validates insurance claims

Preparation tips

Before theft happens

Take these steps now for all your bikes:

  • Record serial numbers: Store in phone, cloud, and written
  • Take photos: Full bike, serial number, unique features
  • Keep receipts: Scan and save digitally
  • Register bikes: Free services like Bike Index
  • Document upgrades: Save receipts for components
  • Update annually: New photos if bike changes

Making your report count

The thoroughness and accuracy of your report directly impacts recovery chances. Even with perfect documentation, police recover only 2-5% of stolen bikes. However, bikes with serial numbers and complete documentation have significantly better odds.

Remember: Only 37% of bike theft victims report to police. By filing a complete report with all necessary information, you're already ahead of most victims and contributing to better crime statistics that drive prevention resources.
