ONYX bikes are valuable, recognizable, and relatively easy to move when they are not properly secured. Theft prevention matters, but knowing what to do after a bike disappears is just as important.
This guide is based on real ONYX theft attempts, stolen bikes, and recovery efforts documented in New York City.
It explains how these bikes are stolen, which security measures have worked in practice, how to prepare for a possible theft, and how to coordinate recovery efforts with police and the ONYX community.
The most important preparation happens before your bike is stolen.
Your ONYX Was Just Stolen? Start Here
If your ONYX has already been stolen, act immediately.
- Contact police. Report the theft and obtain a police report number.
- Check your trackers. Open your GPS tracker, Apple AirTag, or Samsung SmartTag applications.
- Save tracking evidence. Capture screenshots showing locations and timestamps.
- Preserve camera footage. Identify nearby security cameras and ask owners or managers to preserve recordings.
- Gather ownership documents. Locate your purchase receipt, serial number, and photographs.
- Alert the ONYX community. Post clear photographs and identifying details in relevant Facebook groups.
- Stay involved. Monitor comments, answer questions, update your post, and forward credible information to police.
Do not confront suspected thieves or attempt to recover the bike yourself.
If a tracker identifies a possible location, provide that information to police. Tracking coordinates do not necessarily identify a particular apartment, room, or person.
The following sections explain how to prepare for theft, prevent it, and manage recovery efforts.
How ONYX Bikes Get Stolen
Most ONYX thefts do not happen in dramatic ways.
A common situation involves a bike parked outside a home, apartment building, or business.
The bike may be locked, covered, and left in the same location every day.
Nothing happens for weeks or months.
Eventually, someone notices the bike and recognizes the opportunity.
The same bike is visible in the same location, often following a predictable routine.
Then one day it disappears.
From what we have observed in New York City, many theft attempts involve someone trying to ride or roll the bike away.
Not every thief arrives with a truck or van.
Some attempt to defeat the lock, move the bike, or have another person help relocate it.
In other cases, the bike is moved into a nearby building or residence.
This matters because preventing someone from easily rolling or riding the bike away can make a substantial difference.
We have observed theft attempts involving damaged brake rotors, damaged front wheels, and abandoned bikes after thieves attempted to move them with heavy-duty disc brake locks installed.
In the cases we have personally observed, thieves have not successfully removed those locks and ridden away.
That does not mean a disc lock makes a bike impossible to steal.
It means making the bike difficult to move can stop certain theft attempts.
Predictable Parking Increases Risk
Several behaviors repeatedly create opportunities for theft:
- Leaving the bike outside regularly
- Parking in the same location every day
- Following a predictable routine
- Leaving the bike visible from the street
- Assuming a familiar neighborhood is safe
- Leaving the bike unattended without securing it
Even briefly stepping away from an unlocked bike can create an opportunity.
Repeated outdoor storage increases exposure, especially when someone can observe the bike over time.
The longer a bike remains accessible, the more opportunities someone has to plan or attempt a theft.
NYC ONYX Theft and Recovery Data
From Summer 2019 through March 2026:
- 38 ONYX bikes reported stolen in New York City
- 32 recovered
That represents approximately 84% of the documented stolen bikes.
These numbers reflect ONYX theft cases documented through our NYC experience. They are not official citywide police theft statistics and should not be interpreted as the expected recovery rate for every stolen ONYX.
Recovery depends on several factors:
- How quickly the theft is reported
- Whether the bike can be located
- Whether identifying information is available
- Whether ownership can be established
- Whether useful information reaches police
- Whether people recognize and report the stolen bike
Tracking devices, documentation, police involvement, and community participation can all contribute to recovery efforts.
However, no single method guarantees that a stolen bike will be recovered.
How to Protect Your ONYX
The best approach combines secure storage, physical locks, reduced visibility, and tracking devices.
No individual security measure provides complete protection.
Indoor Storage
Secure indoor storage is preferable to leaving an ONYX outside regularly.
Avoid storing the bike outside overnight whenever possible.
Also consider the security of the indoor location.
Shared garages, common storage areas, and buildings with unrestricted access can still present theft risks.
A bike visible through a window or accessible to numerous people may attract attention.
The objective is to reduce both visibility and access.
Heavy-Duty Kryptonite Disc Brake Lock
Based on theft attempts we have observed in NYC, a heavy-duty Kryptonite disc brake lock is one of the most useful physical deterrents.
An alarm is helpful, but the primary advantage is preventing the wheel from rotating freely.
Many thieves attempt to ride or roll an ONYX away.
A properly installed disc brake lock makes that much more difficult.
We have seen attempts that resulted in:
- Damaged brake rotors
- Damaged front wheels
- Abandoned theft attempts
- Bikes that could no longer be moved normally
Moving a roughly 150-pound ONYX with a damaged or immobilized front wheel is difficult.
That additional difficulty can discourage someone attempting to move the bike quickly.
However, a disc brake lock does not prevent multiple people from lifting the bike into a vehicle.
It should be one part of a layered security setup.
Use a visible reminder cable or another reliable reminder system so you do not accidentally attempt to ride with the disc lock installed.
Heavy-Duty Chain
If the bike must remain outside for an extended period, consider a heavy-duty chain securing it to a suitable immovable object.
A chain provides protection against a different theft method.
The disc lock makes the bike difficult to roll or ride.
The chain makes it more difficult to physically remove the bike from its parking location.
Both can be defeated, but using them together increases the effort required.
Bike Cover
A bike cover is another useful deterrent.
It reduces visibility and makes the bike less immediately recognizable.
Someone walking past may not know whether the covered vehicle is an ONYX, another electric bike, or something less valuable.
A cover does not physically secure the bike, but it can reduce unnecessary attention.
Recommended Security Combination
Based on what we have observed in NYC, a practical setup includes:
- Secure indoor storage whenever possible
- Heavy-duty Kryptonite disc brake lock
- Bike cover
- GPS tracker
- Apple AirTag or Samsung SmartTag
- Heavy-duty chain when extended outdoor parking is unavoidable

Prepare Before Your ONYX Is Stolen
Recovery becomes more difficult when owners cannot quickly provide photographs, serial numbers, or proof of purchase.
Do not wait until your bike disappears to gather this information.
Prepare a digital recovery folder that you can access from your phone.
Keep a backup somewhere separate from the phone.
Your recovery folder should contain:
- Original purchase receipt or invoice
- Secondhand bill of sale, if applicable
- Frame serial number
- Additional police identification number, if available
- Original photographs of the bike
- Current photographs showing modifications
- Tracking device information
- Police registration information, if available
- Insurance information, if applicable
This information can help police identify a recovered bike and establish ownership.
It also allows you to create a detailed community theft alert without wasting time searching for old photographs or documents.
Your Original Purchase Email Is Your Proof of Purchase
A bill of sale is not necessarily some complicated document that you need to request from ONYX.
If you purchased your bike online, start with the original purchase email.
That first email confirming your purchase is generally the first record showing that you bought the bike.
Your original paid receipt or invoice provides stronger evidence that the transaction was completed.
The process is simple:
- Open your email.
- Find the original ONYX purchase confirmation or receipt.
- Save a digital copy.
- Back it up somewhere safe.
- Keep another copy accessible on your phone.
That is usually all you need to do to preserve the purchase record you already received.
You do not need to contact ONYX asking for a bill of sale when the original purchase documentation is already sitting in your inbox.
If the original records are genuinely missing, contact the seller or ONYX when appropriate to ask whether replacement documentation is available.
If You Purchased Your ONYX Secondhand
If you purchased a used ONYX and never received a bill of sale, contact the previous owner.
Ask them to prepare and sign a simple document confirming the transaction.
A basic bill of sale should include:
- Seller’s full name
- Seller’s address and phone number
- Buyer’s full name
- Buyer’s address and phone number
- Date of sale
- Description of the bike
- Frame serial number
- Amount paid
- Signatures of both parties
It does not need to be unnecessarily complicated.
Think of it as a receipt documenting who sold the bike, who purchased it, what was purchased, and how much was paid.
If possible, also obtain the previous owner’s original purchase documentation.
Keep everything backed up.
A signed bill of sale helps document the transaction, although it does not independently guarantee legal ownership or satisfy every registration requirement.
Insurance
If your ONYX is insured, keep the policy information in your recovery folder.
Verify that the policy actually covers your specific bike against theft.
Do not assume homeowners, renters, motorcycle, or bicycle insurance automatically covers an ONYX.
Coverage depends on the policy and how the vehicle is classified.
If a theft occurs, follow the insurer’s reporting requirements and deadlines.
Photograph and Identify Your ONYX
Photographs are useful for more than proving ownership.
They help other people recognize your bike.
Take photographs when you first purchase your ONYX, before making modifications.
Then update those photographs whenever the bike changes.
Photograph the Original Bike
Take clear photographs showing:
- Complete left side
- Complete right side
- Front view
- Rear view
- Frame serial number
- Existing scratches or damage
- Distinctive identifying details
Keep the original photographs even after modifying the bike.
Photograph Every Major Modification
Take new photographs after changing:
- Paint or wraps
- Handlebars
- Seat
- Wheels or tires
- Battery covers
- Lighting
- Other recognizable components
Do not simply describe your stolen bike as pink, black, or red.
Show people exactly what it looks like.
A photograph of a custom pink wrap is far more useful than telling hundreds of people to look for a pink ONYX.
The same applies to unusual handlebars, custom seats, modified battery covers, and distinctive damage.
Someone scrolling through Facebook should be able to recognize the bike without needing to ask numerous questions.
Older photographs can also help if modifications are removed after the theft.
Photograph Permanent Identifiers
Accessories and cosmetic modifications can be removed.
Permanent identifying information is especially important.
Document:
- Manufacturer frame serial number
- Additional identification markings
- Distinctive frame damage
- Permanent modifications
- Unusual repairs or welds
Keep complete serial numbers and sensitive ownership documentation in your private recovery folder.
You can provide those details directly to police when needed.
Police Registration and Additional Identification
Contact your local police precinct and ask whether it offers bicycle registration or identification engraving.
Depending on the available program, police may be able to:
- Register identifying information
- Apply an additional identification number
- Record information that can help identify a recovered bicycle
If additional identification is applied, photograph it and save the number.
Keep both the manufacturer’s original frame serial number and any additional police identification number.
These are separate identifiers.
Registration and additional markings can help connect a recovered bike to its owner, but they do not guarantee recovery.
GPS and Bluetooth Tracking Devices
Tracking has been one of the most useful tools in ONYX recovery efforts.
A practical approach is to use two different tracking technologies rather than relying on one device.
GPS Tracker
A GPS tracker can provide location information that helps determine where a stolen bike may have been moved.
Depending on the device, it may provide:
- Current location estimates
- Location history
- Movement notifications
- Timestamps
GPS trackers may require cellular service, subscriptions, or periodic charging.
Location accuracy can also deteriorate indoors or around large buildings.
A GPS location near an apartment building does not necessarily identify the exact apartment containing the bike.
Apple AirTag and Samsung SmartTag
Apple AirTags and Samsung SmartTags use compatible device networks to help locate tagged items.
They operate differently from dedicated GPS trackers.
Their usefulness depends on compatible devices being nearby and reporting location information.
In some situations, compatible nearby phones can help narrow down a location after GPS has identified a general area.
This can be particularly useful when the bike has been moved into a building.
However, neither system guarantees precise indoor location information.
AirTags and SmartTags may also generate unwanted-tracking notifications on compatible phones.
Those alerts can reveal that a tracker is traveling with someone.
Do not assume thieves cannot receive tracking alerts simply because they do not personally own an iPhone or Samsung phone.
Why Use Two Different Trackers?
A dedicated GPS tracker and a Bluetooth finding-network tracker provide different ways to locate a bike.
If one device stops reporting, the other may still provide useful information.
Hidden placement can make trackers harder to discover, but devices can still be located, disabled, or removed.
Tracking improves the possibility of locating a stolen bike.
It does not prevent theft or guarantee recovery.
What to Do Immediately After Your ONYX Is Stolen
The first hours are important because witnesses may still remember what happened, camera footage may still be available, and tracking information may provide useful leads.
Act quickly, but do not put yourself or anyone else in danger.
1. Contact Police
Report the theft immediately.
Provide:
- Bike make and model
- Frame serial number
- Additional identification number, if available
- Current photographs
- Distinctive modifications
- Approximate theft location
- Approximate time the bike disappeared
- Proof of ownership
Obtain the police report number.
Keep it with your recovery documents.
2. Check Tracking Devices
Open your GPS and Bluetooth tracking applications.
If location information is available:
- Save screenshots
- Record timestamps
- Preserve location history when possible
- Continue monitoring for changes
- Provide relevant information to police
Do not assume that a location pin identifies a particular person or apartment.
If a tracker indicates the bike is inside a building, share that information with the investigating officers.
Do not enter private property, confront suspected thieves, or attempt to retrieve the bike yourself.
3. Preserve Security Camera Footage
Identify cameras near the location where the bike disappeared.
Possible sources include:
- Apartment buildings
- Businesses
- Parking facilities
- Residential security systems
- Nearby building entrances
Contact the owners or managers and ask them to preserve footage covering the suspected theft period.
Record the camera locations and provide the information to police.
Security footage may be overwritten automatically.
Waiting several days can result in losing useful evidence.
4. Preserve Other Evidence
Save relevant information, including:
- Tracking screenshots
- Security camera recordings
- Photographs of damaged locks
- Witness information
- Suspicious marketplace listings
- Messages reporting possible sightings
Keep original files whenever possible.
Avoid altering evidence in ways that remove timestamps or identifying details.
5. Alert the ONYX Community
Once you have photographs and basic identifying information ready, publish a stolen-bike alert in relevant Facebook groups.
Do not wait until every detail is available.
You can update the post as additional information becomes known.
Use the ONYX Community to Help Recover Your Bike
Facebook groups and local owner communities can be valuable during recovery.
People may recognize the bike, notice suspicious listings, or report sightings.
However, posting about a stolen ONYX is not a one-time action.
You need to remain actively involved.
Join Relevant Groups Before Theft
Do not wait until your bike disappears to find the communities that might help.
Join relevant ONYX owner groups and local electric bike communities in advance.
Become familiar with where owners share information and report stolen bikes.
If a theft happens, you should already know where to post.
Make Your Stolen-Bike Post Useful
A post saying “My ONYX was stolen, please help” provides very little information.
People need details they can recognize and act on.
Include:
- Clear current photographs
- Date of theft
- Approximate theft location
- Bike model
- Distinctive modifications
- Custom paint or wraps
- Recognizable damage
- Relevant tracking information that is safe to share
- A way to contact you
If you have GPS screenshots, preserve them and provide useful information to police.
Share public tracking updates only when doing so will not expose sensitive locations, interfere with an investigation, or encourage confrontations.
Do not publish your home address, complete ownership documents, or other unnecessary personal information.
Actively Manage Your Post
This is one of the most important parts of using the community effectively.
Do not make a post and disappear for several days.
If people ask questions, answer them promptly.
If someone asks what handlebars, wheels, seat, or battery cover the bike has, provide photographs.
If someone reports a possible sighting, respond and ask for useful details.
If new information becomes available, update the original post.
People who volunteer their time to help need current information.
When questions remain unanswered for days, people may lose interest or move on.
A theft recovery effort benefits from quick communication.
Keep the Original Post Updated
As the situation changes, update the original post with verified information.
Examples include:
- Police report filed
- Additional photographs uploaded
- Identifying details clarified
- Possible sighting reported
- New information provided to police
- Bike recovered
Put important updates near the beginning of the post when possible.
Someone discovering the post later should not need to read dozens of comments to understand the current situation.
Correct inaccurate information when necessary.
Distinguish confirmed information from unverified reports.
Respond to People Who Are Helping
If someone takes the time to report a possible sighting, share your post, or provide useful information, acknowledge their effort.
Community assistance is voluntary.
People are more likely to remain engaged when the owner is actively participating and keeping everyone informed.
The goal is to coordinate useful information, not simply announce that a bike was stolen.
Keep Recovery Efforts Safe
Do not encourage community members to confront suspected thieves.
Do not organize attempts to enter buildings or retrieve the bike without police involvement.
If someone reports a location, ask them to provide information without approaching anyone or putting themselves at risk.
Forward credible leads to police.
Follow Leads and Monitor Resale Listings
Stolen bikes may appear in online resale listings.
Monitor relevant marketplaces and local sale groups for bikes resembling yours.
Do not rely only on the advertised color or model.
Compare details such as:
- Frame appearance
- Handlebars
- Wheels
- Seat
- Battery cover
- Custom modifications
- Scratches or damage
A stolen bike may have some accessories removed or replaced.
This is another reason to preserve photographs taken before and after modifications.
If You Find a Suspicious Listing
Save:
- Screenshots of the listing
- Photographs
- Listing description
- Seller profile information visible in the listing
- Listing date
- Relevant messages or other evidence
Provide the information to police.
Do not arrange a meeting to confront the seller or attempt to recover the bike yourself.
If Someone Reports a Sighting
Respond promptly.
Ask:
- Where was the bike seen?
- When was it seen?
- What identifying details were visible?
- Were any photographs safely obtained?
- Is the information firsthand or something another person reported?
Save the information and forward credible leads to police.
A possible sighting is not confirmation that the bike has been found.
Avoid spreading unverified claims as established facts.
Working With Police to Recover Your ONYX
Police reporting, identification, tracking information, and community assistance should work together.
The police report establishes an official record of the theft.
Serial numbers and identifying marks help distinguish your bike from other ONYX bikes.
Purchase documentation helps establish ownership.
Tracking information and credible sightings may help investigators locate the bike.
When Tracking Shows a Possible Location
If GPS or Bluetooth tracking indicates a possible location:
- Save the location and timestamp.
- Capture screenshots.
- Contact police and reference your report number.
- Provide the tracking information.
- Continue monitoring for changes.
- Share significant updates with the investigating officers.
Remember that location estimates may be inaccurate or delayed.
A location inside a building does not automatically identify a specific apartment or person.
Do not attempt a private recovery.
When Police Recover a Bike
If police locate a bike believed to be yours, they may need documentation establishing ownership.
Be prepared to provide:
- Identification
- Original purchase receipt
- Secondhand bill of sale, if applicable
- Manufacturer frame serial number
- Additional police identification number
- Photographs of the bike
- Photographs of distinctive modifications
The strongest identification usually comes from connecting the recovered bike’s permanent identifiers with your ownership records.
Photographs of modifications and distinctive damage can provide additional supporting evidence.
The release process depends on the circumstances and applicable police procedures.
A receipt or bill of sale can support an ownership claim, but no single document guarantees that a recovered bike will immediately be released.
After Recovery
Once your ONYX has been recovered:
- Confirm the bike’s identity
- Document any damage
- Check whether components are missing
- Inspect locks and security equipment
- Check whether tracking devices remain installed
- Follow any police or insurance documentation requirements
Before riding, inspect the bike for damage affecting safe operation.
Pay particular attention to brakes, wheels, steering, tires, and electrical components.
If the bike was damaged during the theft, have the affected systems inspected before returning it to service.
If you posted a community theft alert, update it to confirm that the bike has been recovered.
Thank the people who contributed useful information.
Final Recovery Preparation Checklist
Every ONYX owner should complete these steps before a theft occurs.
- Store the bike securely whenever possible.
- Install a heavy-duty disc brake lock.
- Use a bike cover when appropriate.
- Use a heavy-duty chain when extended outdoor parking is unavoidable.
- Install and configure tracking devices.
- Save the original purchase receipt.
- Obtain a signed bill of sale for a secondhand purchase.
- Photograph the frame serial number.
- Ask about local police registration or identification programs.
- Photograph the bike from multiple angles.
- Update photographs after modifications.
- Keep original photographs showing previous configurations.
- Back up ownership documents and photographs.
- Keep recovery information accessible from your phone.
- Verify insurance coverage, if applicable.
- Join relevant ONYX Facebook groups before anything happens.
- Know how to access tracking information and save screenshots.
Final Advice
Preventing theft and recovering a stolen bike are two different problems.
Prevention depends on reducing access, visibility, and opportunities.
Recovery depends on identification, documentation, tracking information, police involvement, and timely communication.
A heavy-duty disc brake lock can make an ONYX difficult to ride or roll away. A chain can make it harder to remove from its parking location. A cover reduces visibility. Secure indoor storage reduces exposure.
None of these measures guarantees that a bike cannot be stolen.
If theft occurs, preparation becomes critical.
Your original purchase receipt should already be saved. Your serial number should already be photographed. Your current bike photographs should already be available. Your tracking devices should already be configured.
And if you ask the ONYX community for help, remain involved.
Respond to questions, provide useful photographs, update your posts, and share credible information with police.
The objective is simple: make your ONYX difficult to steal and make it as easy as possible to identify, locate, and recover if someone takes it.
