Non-bike bike gear tested: Foldylock Forever is the most secure folding lock, period.
As someone who lives life on two-wheels, testing bike gear isn’t just a fun hobby – it’s part of my daily life. E-bikes are how I get around and the gear I use with them helps me avoid needing to use a car. And so when I find something new that I incorporate into my everyday kit, that means that it has proven itself as both effective and worth it in the long haul. The latest lock that I trust to use on my own electric bikes is the Foldylock Forever from Seatylock.
Locks for e-bikes can be a touchy subject. We’re talking about expensive transportation machines, and everyone seems to think they know the best lock that is better than anyone else’s. Then, someone inevitably will tell you why that one pales in comparison. Someone will eventually mention Lockpicking Lawyer and say you’re all wasting your time. Basically, there’s little consensus.
But as someone who both rides e-bikes as a daily form of transportation and also has a mechanical engineering degree tucked away in his back pocket for occasional use, hopefully I can shed a little more light on the subject.
I’ve been testing the FoldyLock Forever for several months now, and compared to the literally dozens of e-bike locks I’ve tested, this has become my new favorite model. It’s not cheap – I’ll tell you that immediately. At $125 on Amazon, this sucker is expensive. But good quality isn’t cheap, and if I could go back and spend that $125 before my $3,000 e-bike was stolen last year, I’d do it in a heartbeat.
There are a few reasons I’ve fallen in love with the Foldylock Forever. First of all, folding locks are much more convenient than chains because they provide high-security in a much more manageable package. I still recommend using more than one lock of different styles at the same time, but now the Foldylock Forever is definitely the first lock I grab.
The lock folds up to fit in your hand or and can be securely mounted in a smaller area of your bike with the included holster, yet it still gives you the adaptability of a chain to lock around or through weird-shaped objects like trees, quirky bike racks, etc. Compared to high-security chain locks that can weigh 11-15 lb (4.9-6.8 kg), the Foldylock Forever weighs just 3.9 lb (1.8 kg). There are simply fewer links that need to be beefed up to reach that level of security compared to a chain lock.
The holster is ultra-convenient to use because there are no additional straps or fasteners – the molded shape securely holds the lock without rattling and you simply slide it out when you’re ready to use it.
Folding locks are also largely impervious to leverage attacks (like when thieves put a car jack in a U-lock). Cheaper folding locks can still be vulnerable to bolt cutters or nut splitters, but the Foldylock is hardened against both attacks. The hardened steel links defeat bolt cutters and use high-security rivets with such high precision that you can’t get a nut splitter in there.
When Foldylock claims that this is the most secure folding lock in the world, that isn’t marketing speak or hyperbole. It’s been tested and certified as such. It not only gets their own highest security rating, but it is Gold-Certified by Sold Secure, an independent, UK-based non-profit organization that tests and certifies locks based on how hard it is for them to be defeated by various attacks.
It’s not the only folding lock to reach this high level of certification from Sold Secure, but the lock is currently undergoing testing from other international lock-certification agencies that have never been achieved by folding locks.
Compared to other folding locks on the market, many of which I’ve tested, the Foldylock Forever is also much quieter and easier to use. Others have more play in their joints and a jingle-jangle sound similar to chains. Many have a limited 90-degree swing at the locking point, meaning it can’t really open all the way like a straight link. But the Foldylock Forever’s extremely high tolerances mean there’s no noise and the locking point can spin all the way around, effectively making it into a full circle (or rather, hexagon) that doesn’t limit your ability to lock around weird-shaped objects.
You don’t have to take my word for it – just look at the reviews. On Amazon, it has a 4.6 out of 5 rating, which is basically unheard of in the lock category. Part of that is because locks just aren’t a sexy product. When they work well, people don’t think about it. But when they don’t work well, people run to Amazon to complain about it in a bad review. That means keeping review numbers high on products like these is a feat in and of itself.
I won’t spend too long on this last issue, but just to address the “what about thieves that pick the lock?” argument that inevitably comes up from pedants, that’s basically a red herring. Most bike thieves, even the professionals, come prepared to break a lock, not pick it. And if someone truly is skilled enough to pick these types of cylinders (think “Lockingpick Lawyer” level professional), then the bike is already theirs. A good lockpicker is the same thing as having the key. There’s nothing you can do about it. Sure, the cylinder on the Foldylock Forever has higher security than a cheap bike lock. But nothing stops a truly professional lock picker because they effectively have a key to everything.
I’ve tested a lot of locks, but I’ve never found one that is as secure, lightweight, and convenient all at the same time. It’s not cheap at $125, but for an electric bike that is also not cheap to replace, investing in a solid lock is critical, in my opinion. I’ve been using the Foldylock Forever on my own bike and my wife’s bike, meaning I trust my family’s gear to it.

The US Department of Energy (DOE) today announced $1.2 billion in financing to replace Puerto Rico’s fossil fuel plants with solar and battery storage through 2032.
The DOE’s Loan Programs Office announced two conditional commitments and one loan closing to power producers in Puerto Rico. Each supports a project contracted with the Puerto Rico Electric Power Authority. The announcements include:
- The closing of a $584.5 million loan guarantee to subsidiaries of Convergent Energy to finance a 100 MW solar farm with a 55 MW (55 MWh) battery energy storage system (BESS) in the municipality of Coamo and BESS installations in the municipalities of Caguas (25MW/100MWh), Peñuelas (100MW/400MWh), and Ponce (up to 100MW/400MWh)
- A conditional commitment for a loan guarantee of up to $133.6 million to a subsidiary of Infinigen for a 32.1 MW solar farm with an integrated 14.45 MW (4.76 MWh) BESS, and a co-located standalone 50 MW (200 MWh) BESS expansion in the municipality of Yabucoa
- A conditional commitment for a loan guarantee of up to $489.4 million to a subsidiary of Pattern Energy for three stand-alone BESS in the municipalities of Arecibo (50 MW/200 MWh), and Santa Isabel (50 MW /200 MWh and 80 MW/320 MW), and a 70 MW solar farm with an integrated BESS in the municipality of Arecibo.
If all are finalized, these projects would more than double LPO’s support for utility-scale solar generation and battery energy storage in Puerto Rico.
LPO provides low-cost financing and a rigorous due diligence process, making it a valuable resource for Puerto Rico as it works to rebuild an affordable, reliable, and clean energy system. As a result of reliance on imported fuel, the persistent threat of tropical storms, and underinvested infrastructure, Puerto Ricans today face average energy costs that are twice the US average – all while consuming only one-quarter of the energy of the US per capita.
LPO’s initial loan to a power producer in Puerto Rico, Project Marahu, closed in October 2024, and when complete will add more than 200 MW of solar and up to 285 MW of stand-alone energy storage to Puerto Rico’s grid.
Through its September 2023 partial loan guarantee to Project Hestia, LPO also supports virtual power plant (VPP)-ready rooftop solar and battery storage installations in Puerto Rico. As a nationwide project, Hestia’s sponsor is committed to at least 20% of installations under Project Hestia going to homeowners in Puerto Rico.
As part of its procurement plan, Puerto Rico Electric Power Authority seeks to install 1,500 MW of battery storage and requires a minimum capacity of storage to be co-located with each utility-scale solar project. Energy storage systems currently online in Puerto Rico are being dispatched every day.
When including Marahu, LPO’s closed and conditionally committed financing supports over 100% of the capacity Puerto Rico Electric Power Authority aimed to procure under its initial request for energy storage project proposals, the first of six.

Chevy just introduced new deals on the Equinox and Blazer EV models to make them even more affordable. With 0% interest and a new trade-in bonus, Chevy is offering over $5,000 in savings.
Chevy adds new Equinox and Blazer EV deals in January
Although the Chevy Equinox EV is already “the most affordable” EV in its class with over 315 miles range, it’s getting even cheaper.
Earlier this week, Chevy launched new deals on the 2024 Equinox and Blazer EV models. According to a note sent to dealers, viewed by CarsDirect, the electric SUVs are now available with 0% APR financing for 60 months. You can also choose from 0.9% AP for 72 months and 2.9% APR for 84 months.
This marks the best financing offer on Chevy’s newest EVs to date. The previous best rates were 0.9% APR for 60 months, 3.9% for 72 months, and 5.9% for the longer 84-month option.
On a 7-year $45,000 loan, online auto research firm CarsDirect estimates the new deals amount to around a $5,200 price cut. The lower APR rates are already offered on the Chevrolet Silverado EV pickup.
In addition, Chevy is offering a trade-in bonus of up to $3,000 on the Silverado EV and $1,000 on the electric Equinox and Blazer models. If you choose to lease, the bonus is cut in half: $1,500 for the Silverado and $500 for the electric SUVs.
Chevy’s new EV deals started on January 14 and run through March 3, 2025. The deals come as rivals like Hyundai and Ford recently launched new EV promotions.
On Thursday, Hyundai launched a new promo on the upgraded 2025 IONIQ 5, which includes monthly leases as low as $199 and a free ChargePoint home EV charger (or $400 charging credit). Meanwhile, Ford extended its “Power Promise” program earlier this month, which also includes a free home charger, among several other benefits.
The 2024 Chevy Equinox EV started at $41,900 with up to 315 miles range. Prices for the electric Chevy Blazer start at $43,690 with up to 279 miles range.
