There’s a number hidden somewhere on basically every electric bicycle – or pedal bicycle – including the one in your garage. If you haven’t found it yet, you should do it today. Here’s why.
That number is the frame number, and for all intents and purposes, it’s basically like a VIN but for a bike. The VIN (Vehicle Identification Number) on your car is the number that gives it an identity and helps track it down if it’s ever stolen.
The same goes for your bike’s frame number. This innocuous string of characters, often stamped inconspicuously beneath your bike’s bottom bracket or on the head tube, isn’t just there to fill space – it can be the key to protecting your bike from theft or recovering it if the unthinkable happens.
Why is the frame number so important? Simply put, it’s your bike’s fingerprint, a unique identifier that distinguishes your ride from every other two-wheeler out there. In a scenario where your e-bike goes missing, having this number documented can drastically improve the odds of it being returned by law enforcement.

Rad Power Bikes recently shared some great tips on the importance of knowing your frame number and where to find it. As you can see in the images below, the number is usually stamped into the frame on the bottom of the head tube (the front of the bike), or under the bottom bracket (the underside of the bike where the pedals are connected).
But knowing your frame number is only half the battle. The next critical step is registering that number with a bike registry. Fortunately, several trustworthy services offer free registration, creating a central database accessible by law enforcement, bike shops, and fellow cyclists who might stumble upon your stolen steed.
Bike Index (bikeindex.org) is one of the most popular platforms, boasting thousands of successful recoveries and a simple, intuitive registration process. And the best part is that it’s free! Another solid option is Project 529 (project529.com), widely used in North America and highly praised by police departments for its effectiveness in tracking stolen bikes. Again, it’s free to use!
Additionally, some local municipalities offer their own registries, such as the National Bike Registry (nationalbikeregistry.com), which collaborates directly with law enforcement to streamline the reporting and recovery process.
These types of services offer a form of passive protection, where you can mark your bike as stolen in their registries and then hope that someone finds it. In the event that someone does find your bike (such as in a shady Craigslist sale, etc.) and decides to check the frame number against the databases, they’ll see it’s stolen. If the police raid a bike theft ring and find a cache of stolen bikes, they may run all their frame numbers and find that yours is in the mix.
If you want protection that is a bit more active, there are full-on insurance options (though your renters or homeowner’s insurance may cover your e-bike), or theft protection services like Tempo that aren’t technically insurance, but operate somewhat similarly by offering a combination of holographic tracking number stickers for the bike combined with up to $2,500 in coverage for a replacement bike, if they can’t recover your stolen bike. I had the chance to sit down with Tempo’s founder Michael Keating at Micromobility America late last year, and you can see more about what I learned from him here.
This is probably a good time for a reminder to us all that a good lock is usually the only thing standing between our precious e-bike and those who want to take it from us.
I’ve reviewed a ton of locks, but some of my favorites include the Foldylock Compact for its high security, smaller size, and ease of locking to various sizes/shapes of bike racks, or the Foldylock Forever which is the big brother of the Compact and is nearly as impenetrable as it gets for a bike lock, as confirmed by the top bike lock testing agencies in the world.
For those who prefer a U-lock instead of a folding lock, my go-to lock is the Mason 220. Again, it is one of the top-rated locks, but it’s also wide enough to fit around the battery-fattened downtube of my e-bikes. That’s rare in the world of U-locks, and so the fact that it carries so many high-level awards and certifications is icing on the cake.
But no matter how good your lock is, there’s always a chance that your e-bike can be separated from you. And so the long and the short of it is that every e-bike has a unique identifier on it, and finding that frame number is your best chance of getting your bike back if it is ever stolen.
So take a minute today and locate your frame number to write it down or take a picture of it. Better yet, take a selfie with it and yourself. If you ever need to quickly prove that it’s your bike to a police officer on the sidewalk (such as if you followed an AirTag right to the bike), that’s a great way to do it.
I’ve had my e-bike stolen more than once, and the only way to curb that sinking feeling is to get it back. Taking a few minutes now to locate your frame number and register your e-bike can save you countless headaches later. After all, an ounce of prevention is worth several thousand dollars worth of cure when it comes to stolen bikes. So flip that bike upside down, jot down your frame number, and give yourself some peace of mind.

Tesla is trying to use a piece of property in Australia, near Adelaide, in order to build a battery factory and Tesla showroom. But it’s facing steep opposition from locals, most of whom cite dissatisfaction with Tesla CEO Elon Musk as their reason to oppose the project.
The plans center on Marion, a small city of population 4,101, a suburb of Adelaide, the capital of South Australia.
Last month, a developer submitted plans to use a piece of land referred to as Chestnut Court Reserve, which has been inaccessible to the public since 2016 due to contamination concerns. Plans to develop the location would involve a requirement to clean up the contamination on the site.
They would also involve the cutting of several trees on the site, some of which have been deemed as “dead or ill health,” with a plan to plant trees at another site to make up for any removals.

The developer said it would use this land to build a new fit-for-purpose factory facility that would be used by Tesla both as a showroom and service center for Tesla vehicles, and also a facility that could be used for “repurposing of Tesla batteries.”
The plan doesn’t go too deep into the specifics of how said repurposing would happen, but it could involve using Tesla vehicle batteries in Powerwalls, or in Tesla’s Powerpack grid storage projects, which are quite popular in South Australia, where they have helped to solve some of the region’s significant power stability problems.
The developer makes the case that Tesla already has a presence in the area in neighboring Tonsley, that Tesla’s mission (and the specific mission of a battery recycling center) supports the environmental goals of the community, and that the facility would create around 100 full-time jobs in the local community, including highly skilled jobs like battery researchers.
All in all, the developer thinks it would inject $56 million into the local community, quite a nice chunk of change for the small town.
And the city council also supports the plan, thinking that the job and economic benefits are worth it, particularly given that the land is not being used for anything else.
The plans were submitted, the residents were consulted, and now that all the chips are on the table… the residents aren’t having it.
Residents respond with a lot of language we shouldn’t say here
The local community gave significant pushback to this idea, with some ~95% of residents disapproving the plan. The city received 948 comments on the plan, which sounds like quite a lot for a city of 4,101 people. However, half of those comments came from outside the city’s area.
But among those comments from the immediate area of the development, only 11 comments favored the plans, with 121 opposing them (that’s 92% opposition).
Among the comments (quoted by The Guardian) come these gems, which wonderfully showcase the stereotypical Australian predilection for colorful language:
“Because Elon Musk is a [redacted] human being and a [redacted]!”
“Elon Musk and Tesla are a [redacted] on humanity”
“Elon Musk is a full blown [redacted]”
“Destroying trees to build a factory for a company owned by a [redacted] would be a vile choice”
“We should not support and put money in the pockets of a [redacted] who openly [redacted] salutes, is [redacted] human”
We’ll let you try to fill in some of those words, though we’re pretty sure what some of them are (and, honestly, while I somewhat understand the point of redacting profanity in public records, I’d say it is a little absurd to redact “nazi”).
The plans haven’t received their final vote yet, and the council still seems like it wants to convince the local community to go forward with them. But some residents suggest that the site could be better used by other companies, and that alternate uses could help to preserve that land and also avoid potential image concerns for the area as protests against Tesla continue globally.
Some other comments, perhaps wrongly, called the possible building “a noisy, ugly, planet-destroying temple to billionaires.”
While it’s disappointing to see a proposed recycling facility referred to thusly (although Tesla does have a questionable history when it comes to following local environmental rules), it’s just another sign of how Tesla CEO Elon Musk is drastically affecting the brand, and holding it back from its stated mission to advance sustainable transport.
Response shows once again that Musk is harming Tesla
The backlash, like Musk’s advocacy, has been global. Tesla sales are dropping in most regions, even as EV sales rise as a whole. Specifically in Australia, Tesla sales saw a big drop year-over-year. And this has applied to corporate customers too, with Tesla losing corporate sales as multiplecompanies have cited their distaste with the CEO.

The world’s leading electric vehicle (EV) maker is rapidly expanding overseas. After taking control of vehicle sales in Germany last year, BYD is about to do the same in another key overseas EV market.
BYD to take control of EV distribution in Australia
Last August, BYD reached an agreement with Heden Mobility Group to acquire Heden Electric, which was responsible for importing its vehicles and spare parts for sale in Germany.
The move gives BYD more control over pricing and other areas of distribution as it expands the brand overseas. By taking over control, the company can sell its vehicles directly to buyers. And, it can also set prices.
According to EVDirect, BYD’s official distributor in Australia, the company is preparing for a similar move in the region. Luke Todd, founder and chairman of EVDirect, said the takeover would help unlock BYD’s potential in Australia.

Todd said the first phase was proving that the “BYD brand would thrive here,” and the next phase will make EV ownership “easier and more accessible than ever.”

Since launching its first vehicle, the Atto 3 SUV, in 2022, BYD has become one of the fastest-growing car brands in Australia.
BYD now offers a complete lineup of six vehicles, ranging from the low-cost Dolphin and Atto 3 to mid-size SUVs (Sealion 6 and 7), electric sedans (Seal), and even a pickup (Shark 6).

Earlier this year, the company introduced a new entry-level “Essentials” trim, slashing prices across its entire lineup.
According to TheDriven, BYD has three of the top 10 best-selling electric vehicles (EVs) in Australia as of April. The Sealion 7, launched in just February, placed fifth with 1,473 units sold, trailing the Tesla Model Y (3,394), Model 3 (2,266), MG4 (1,698), and Kia EV5 (1,509).

BYD’s Atto 3 took sixth (956) while the Seal (637) and Dolphin (431) placed ninth and 14th through the first four months of 2025, respectively.
Taking control of distribution is expected to help improve service for current BYD drivers and will likely boost EV adoption in Australia.
Electrek’s Take
BYD’s sales are surging in China and overseas. In April, BYD sold more electric vehicles (EVs) in Europe than Tesla for the first time. Now, it’s launching its best-selling and most affordable electric car, the Dolphin Surf (also known as the Seagull EV in China).
S&P Global Mobilityis calling for BYD to more than double its sales in Europe this year to around 186,000 units.
And clearly it’s not just Europe. BYD is quickly establishing its presence in major overseas markets, including Mexico, Brazil, Thailand, Australia, New Zealand, and many others.
With local production coming online and new, custom-tailored vehicles launching, BYD is laying the groundwork to continue gaining global market share over the next few years as the industry shifts toward electric vehicles. And that’s not even scratching the surface, with BYD’s new battery and ultra-fast EV charging technology set to change the game.
