Your e-bike cost somewhere between £1,000 and £5,000. It sits in your shed, your hallway, or chained to a railing outside your flat. And right now, if someone stole it, the police would ask you for a serial number you’ve never written down, a receipt you can’t find, and a description that amounts to “it’s a black electric bike.” That’s not a recovery — it’s a report that goes nowhere. Registration takes ten minutes and massively improves your chances of getting it back.

Why Registration Matters for E-Bikes
E-bikes are disproportionately targeted by thieves. They’re expensive, in high demand second-hand, and difficult to identify once the battery and display are removed. A £3,000 e-bike can be stripped down to an anonymous frame in minutes.
Registration creates a link between you and your bike that survives theft. When police recover stolen bikes — and they do, often during raids on organised theft operations — the first thing they check is the serial number against the national database. If your bike isn’t registered, they can’t return it to you. It sits in a police storage facility and eventually gets auctioned or scrapped.
According to BikeRegister, the UK’s national cycle database, registered bikes are twice as likely to be recovered and returned to their owners compared to unregistered bikes. Given that registration is free or costs a few pounds, there’s no reason not to do it.
The Scale of E-Bike Theft in the UK
The Office for National Statistics reports roughly 75,000 bicycle thefts annually in England and Wales. E-bikes represent a growing proportion as ownership increases. The average value of a stolen e-bike is several times higher than a regular bicycle, making them a preferred target. London, Manchester, and Bristol have the highest rates, but no area is immune.
Where to Register Your E-Bike in the UK
BikeRegister (Recommended)
BikeRegister is the UK’s largest cycle registration database, used by every police force in England, Wales, Scotland, and Northern Ireland. When police recover a bike, they check BikeRegister first.
- Basic registration: Free. Records your bike’s details and serial number
- Membership with marking kit: about £15-30. Includes tamper-proof QR code stickers and an ultraviolet security marking kit
- How to register: visit bikeregister.com, create an account, and enter your bike’s details
The free tier is sufficient for database registration. The paid tier adds physical markings (covered below) and enhanced listing features. I’d recommend at least the basic paid tier — the stickers alone act as a visible deterrent.
Immobilise
A broader property registration database (not bike-specific) used by UK police for all types of valuable property. Free to register. Useful as a secondary registration alongside BikeRegister.
Your Local Police Force
Some police forces run their own marking and registration events — usually at community centres, cycling events, or police stations. These are free and often include a physical marking with a UV pen. Check your local force’s website for upcoming events.
How to Find Your E-Bike’s Serial Number
Every bike has a unique serial number stamped into the frame during manufacture. For e-bikes, there may be additional serial numbers on the battery and motor. You need all of them.
Frame Serial Number Location
The most common locations:
- Bottom bracket shell — turn the bike upside down and look at the underside where the pedal cranks meet. This is the most common location and where police check first
- Head tube — the vertical tube at the front where the handlebars stem enters the frame
- Seat tube — stamped on the rear of the tube below the saddle
- Rear dropout — where the rear wheel axle sits, on the inside of the frame
The serial number is typically 6-12 characters — a mix of letters and numbers. It’s stamped into the metal, not on a sticker (stickers can be removed).
Battery Serial Number
Your e-bike battery has its own serial number, usually on a label on the battery casing. Record this separately. Batteries are expensive (£300-800 to replace) and are sometimes stolen independently from the bike. Knowing the battery serial helps if it’s recovered separately.
Motor Serial Number
The motor (hub or mid-drive) also has a serial number, typically stamped on the motor housing. For mid-drive motors like Bosch or Shimano, this is on the drive unit. For hub motors, it’s on the hub shell.
What Information to Record
Create a document (digital — stored in cloud, not just on your phone) with:
- Frame serial number
- Battery serial number
- Motor serial number
- Make and model (e.g., “Cube Reaction Hybrid Pro 625”)
- Frame size (e.g., “54cm” or “Large”)
- Colour (be specific — “matte black with orange decals,” not just “black”)
- Purchase date and price
- Receipt or proof of purchase (photo of receipt, email confirmation, bank statement showing the transaction)
- Clear photographs — at least four: both sides, front, and a close-up of any distinguishing marks, scratches, or custom accessories
- Accessories — any aftermarket additions (lights, rack, mudguards, computer) with their own serial numbers if applicable
- Key number for the battery lock (if applicable)
Store this information somewhere that survives a phone being lost or stolen. Google Drive, iCloud, email it to yourself — anywhere cloud-based that you can access from another device.
It’s also worth sharing this document with a partner or family member. If your bike is stolen while you’re away from home, someone else can start the reporting process with all the details to hand. Every hour matters — bikes that appear on marketplaces within 24 hours are easiest to intercept.
Marking Your E-Bike
Registration records your bike in a database. Marking physically identifies the bike itself — and visibly deters thieves.
QR Code Stickers
BikeRegister’s membership kits include tamper-proof QR code stickers that link directly to your registration. Scanning the sticker shows the bike’s registration status. These are visible to potential thieves (deterrent effect) and survive attempts to peel them off — they fragment rather than coming away cleanly.
Apply stickers to:
- Head tube — visible from the front
- Seat tube — visible from behind
- Down tube — the largest visible surface
UV Marking
An ultraviolet security pen lets you write your postcode and house number (e.g., “RG9 1AB/42”) on the frame in invisible ink. It’s only visible under UV light. Police carry UV torches for exactly this purpose when checking recovered bikes.
Write your marking on:
- Inside of the seat tube (accessible when the seatpost is removed)
- Underside of the down tube
- Inside of the battery compartment
Frame Engraving
The most permanent option. Some bike shops and police events offer frame engraving with a unique code. It can’t be removed without visibly damaging the frame, which makes the bike harder to sell. The downside is it slightly reduces the frame’s resale value if you ever sell legitimately — but the security benefit outweighs this for most owners.
What to Do If Your E-Bike Is Stolen
Immediately
- Report to police. Call 101 (non-emergency) or report online through your local force’s website. You’ll get a crime reference number — you need this for insurance
- Mark as stolen on BikeRegister. Log in and flag your bike. This alerts police nationally if the serial number is checked
- Tell your insurer. Most policies require notification within 24-48 hours. Our guide to e-bike insurance covers what’s typically included
Within 24 Hours
- Check online marketplaces. Facebook Marketplace, Gumtree, eBay, and Shpock. Stolen bikes often appear within days. Search by brand, model, and location. Set up alerts
- Post on social media. Local cycling groups on Facebook are remarkably effective. Cyclists look out for each other. Include a photo and the crime reference number
- Check BikeRegister’s stolen bike alerts. Other users may spot your bike
If You Find It Listed Online
Do not confront the seller. Contact police with the listing link and your crime reference number. Police can arrange a test purchase or attend the collection. Confrontations over stolen property can turn dangerous.
Insurance and Registration
Most e-bike insurance policies don’t explicitly require registration, but several offer discounts (typically 10-15%) if your bike is registered on BikeRegister and marked. Some specialist policies — particularly for bikes over £3,000 — require it.
If you’re considering insurance, registration makes the claims process faster and smoother. The insurer needs proof of ownership, and a registration record with photographs is far stronger evidence than a verbal description.
For bikes stored outside or in communal areas, insurance is strongly recommended. Check our e-bike insurance guide for UK policy comparisons.
Additional Security Measures
Registration is one layer of protection — but it works best as part of a multi-layered approach. Thieves are opportunistic, and every additional barrier you add reduces the chance they’ll target your bike over someone else’s. Here’s what to combine with registration:
Physical Locks
Two different lock types (D-lock plus chain) are better than one expensive lock. The D-lock secures the frame and rear wheel to the anchor point; the chain secures the front wheel. Sold Secure Gold or Diamond rated locks are what insurers look for. Budget at least £40-80 for locks — spending less than 10% of your bike’s value on security is false economy.
Lock through the frame, not just a wheel. A wheel is removable in 30 seconds. The frame is the bike.
GPS Tracking
A hidden GPS tracker gives real-time location if stolen. Some integrate with BikeRegister and send alerts if the bike moves unexpectedly. Costs £30-100 for the device plus a small monthly subscription (typically £3-5). For a £2,000+ e-bike, this is cheap peace of mind.
Hide the tracker inside the frame tube (down tube is most common), under the saddle, or inside a hollow handlebar. The more hidden, the less likely a thief discovers and removes it.
Battery and Display Removal
Always take the battery with you when locking up in public. A bike without a battery is worth far less to a thief, and the battery is often the single most expensive component to replace. The battery guide covers why these are such valuable targets.
If your e-bike has a removable display unit (Bosch Kiox, Shimano SC-E6100), take it with you. Without it, the motor doesn’t function — the bike is essentially a very heavy regular bicycle.
Secure Storage
A locked shed with a ground anchor is better than a garden. Inside the house is better still. A rear rack with a pannier lets you carry the battery easily when parking.
For sheds and garages, a ground anchor (about £20-40 from Screwfix) bolted to a concrete floor with a heavy chain through the frame is the gold standard. Shed alarms (about £15-20) add an audible deterrent.
Routine Variation
Don’t lock your bike in the same spot at the same time every day. Organised thieves case locations and learn patterns. If you commute by e-bike, vary where you lock up when possible — different racks, different sides of the building.
Frequently Asked Questions
Is it a legal requirement to register my e-bike in the UK? No. There’s no legal obligation to register a bicycle or e-bike in the UK (unlike motor vehicles). Registration is voluntary but strongly recommended for recovery purposes. Some local authorities run registration schemes, and police encourage it.
Does BikeRegister cost money? Basic registration is free and records your bike in the national police database. Paid membership (about £15-30) includes tamper-proof stickers, a UV marking kit, and enhanced listing features. The free tier is sufficient for database registration alone.
Can I register a second-hand e-bike? Yes. If you’ve bought a second-hand e-bike, register it in your name with the serial number and your proof of purchase. If the bike was previously registered by the original owner, BikeRegister can transfer ownership with appropriate documentation.
What if my e-bike doesn’t have a serial number? This is unusual for branded e-bikes but can happen with budget imports. You can get a unique frame number engraved at a bike shop or police marking event. BikeRegister can also assign a virtual identifier to bikes without factory serial numbers.
Will registration help recover my stolen e-bike? It makes a real difference. BikeRegister data shows registered bikes are twice as likely to be recovered. Police check the database when they recover stolen bikes, and without registration, there’s no way to link a recovered bike to its owner.
