linka lasso smartphone chain lock

I’d like to think that the only thing I need to live a car-free life is my bike and my enthusiasm. But it’s the extra gear that helps me stay as two-wheeled as possible. In this regular column, I take a deep dive into some of the coolest and most interesting gadgets and pieces of kit that make it possible to swap a car for an e-bike on a daily basis. This time, we’re checking out a fascinating smartphone-controlled keyless e-bike lock called the Linka Lasso.

That’s right, there’s no physical key shipped along with the Lasso, at least not of the metal variety. There is an optional SmartMotion key that works like a fob in a keyless ignition car, but for the most part, the lock is operated completely by your phone.

I tested two versions, the Linka Lasso 8 and Linka Lasso 10 Moto. They have the same locking mechanism, but 8 and 10 mm hardened steel links, respectively. The Lasso 8 is also shorter with 100 cm (39 inch) chain length, while the Lasso 10 Moto has a larger 140 cm (55 inch) locking circumference. Theoretically, the smaller chain would be fine for e-bikes, while the larger one is meant more for motorcycles, but I’d opt for the larger one on my e-bikes just to give me more room and freedom to lock more of the frame and/or wheels to secure objects.

They both have the same Sold Secure Silver rating, though the thicker hardened steel chain links on the Lasso 10 surely stand up to attacks for longer.

The general idea of the lock is that you use the accompanying smartphone app to unlock Lasso, meaning you don’t need to put yet another key on your crowded keyring. And if you’re the kind of person that only bikes occasionally and thus don’t walk around with your bike lock’s key on you all the time, you don’t need to remember to grab the key on the way out since your phone IS the key.

And to answer the question many of you already thinking, there’s a solution for when your phone’s battery runs out. During the lock setup routine, you have to create a secret code that you enter through the single push button on the lock, which unlocks it.

Granted, that solution is a bit cumbersome to use since there’s only a single button, and so it takes a lot longer to punch in a code than with a typical wheeled combo lock. But it’s not something you’d ever do unless your phone actually died while your bike was locked up, which I imagine is a pretty rare occurrence. If you’re like me, you starting sweating when your phone battery is under 50%. If you’re a psychopath like my wife that can giggle as your phone battery dips down to 2%, you may want to remember that secret lock code.

Using the lock for the first time is kind of mind-blowing. The first time you push a software button on your phone and hear your bike chain make a whirring noise then release itself, it kind of blows your mind. It’s a real “welcome to the future” moment.

That lock mechanism feels super solid, which it better, since it’s also housing the lock’s battery and electronics. A special little magnetic charging cable is included to charge up the lock, and you better not lose that little cable because of course it’s not the same cable as the one you use to charge your phone.

As cool as unlocking your bike lock from your phone is, the device also works with smartwatches. I don’t have a smartwatch, but the Lasso is compatible with many leading smartwatches which means I wouldn’t even actually have to pull out my phone to unlock it, if I had a smartwatch.

Obviously, unlocking via a smartphone is the main trick here. But the Linka Lasso is a lot more than just a smartphone lock. The same technology that allows the smartphone-based unlocking also opens the door to a number of other cool features.

First of all, the lock has an optional SmartMotion key, which is basically a proximity tag that you can put on your keyring. But it’s not a direct replacement for a physical key – meaning it’s not just a fancy electronic version of a cut steel pin that you still have to fetch from your keychain. You don’t swipe it or hold it up to the lock like an NFC card. It can stay in your pocket while allowing the Linka Lasso to unlock from the push button on the lock simply by recognizing that the tag is less than one meter (3 feet) away from the lock. That means when you have the SmartMotion key on you, you don’t even have to pull out your phone to unlock your bike. You simply walk up to the lock and push a button. It’s basically the same idea as keyless ignition cars that recognize the key fob is sitting in your pocket.

That makes the lock super fast to use. Instead of fumbling in your pocket for keys, unlocking the lock, and then fumbling to put your keys away, you simply walk up to the lock and push a button. It unlocks instantly since it reads the SmartMotion key in your pocket. The process takes literally two seconds. Most of us aren’t so stressed that an extra 20 seconds of key fumbling is going to ruin our day, but it does feel pretty nice to skip that step and just ride away from the bike stand in seconds.

Next, the connected nature of the lock allows you to actually share unlocking credentials with other people. For example, if my wife and I share a bike, we can also share the “key” to the lock by both being able to unlock it from our phones. Or if you leave your bike at a buddy’s place, you can give him access to unlock it. You can even pair multiple Linka locks, like their Dutch-style wheel lock, to your phone to unlock them all together.

I should also mention that it’s nice to see that the lock comes with a 5-year warranty. I sometimes worry about how well electronics will hold up when they’re built into things that get knocked around every day.

What’s the downside?

The first bummer of chain locks is simply that they’re heavy. The Lasso 8 weighs 1.8 kg (3.9 lb), and the Lasso 10 Moto weighs a hefty 3 kg or 6.6 lb. My current favorite lock weighs half of that and has a higher security rating, meaning the Linka Lasso doesn’t win on a per-pound basis. But then again, it does what other locks can’t on the technology side, so the trade-off is there for each person to weigh on their own.

Next, there’s the issue of battery life. They say that the Linka Lasso’s battery will last for two months if you’re using it with the app, or up to 5 months if you only use the proximity key. That’s pretty good, in my opinion, until you forget that you need to be charging it. As long as you set a reminder to charge it once a month or so, I think it won’t be an issue. But if you ever forget, you’ll be SOL until you bring a little portable battery charger out to your bike, at which point the lock will fire right back up.

The lock will also give you notifications that its battery is running low via the smartphone app, so in all fairness, it does its best to not let you forget about it.

They’re also not cheap, not by a long shot. The Lasso 8 is currently on sale for $149, and the Lasso 10 Moto is on sale for $179. Oh, and if you want that SmartMotion key, that’s an extra $25. You’re really paying for the features here, since while Sold Secure Silver is quite good, there are higher-rated locks for lower cost. So again, it’s not a dollar per dollar basis here, but rather paying for fancier features.

Oh, and it’s got that special little magnetic charging port, meaning if you ever lose that weird little charger, you’ll also be up a creek unless you head back to the Linka to get a replacement. That’s not a charger you’ll find at the corner store.

So while there are definitely some downsides, the Lasso has some major upsides that I haven’t seen in any other lock on the market. If it was Sold Secure Gold instead of Silver, I’d be over the moon. But as it stands, I think it’s a great second lock to add your security regiment. Because you’re definitely not locking your nice e-bike up with only one lock, right?!

Fast charging just got sleeker: Delta's 50kW Wallbox launches in US

Fremont, California-based Delta Electronics just rolled out a sleek new 50kW DC Wallbox charger that’s designed for tight spaces at ACT Expo 2025.

This charger packs a punch in a surprisingly slim, 10-inch-thick, and lightweight (just 225 pounds!) casing that can be wall-mounted or set up on a pedestal. It’s specifically designed for tight spaces like urban parking lots, busy corporate campuses, or crowded fleet operation hubs.

Delta plans to manufacture these 50kW DC Wallbox chargers in Plano, Texas, keeping it local and supporting the rapid EV infrastructure growth across North America.

A 50 kW charger is at the low end of Level 3 fast charging speed, because you don’t always need to charge your car in 25 minutes. It’s the ideal charging speed for shopping, lunch, or seeing a film. Eng Taing, Delta’s senior VP and GM of energy & telecom Infrastructure, says, “Our focus is on seamlessly integrating high efficiency charging into the diverse scenarios of everyday life, including commercial operations, not just maximizing power output.”

With a 97% efficiency rate, the Wallbox can juice up two EVs simultaneously using either CCS1 or NACS connectors. Plus, the 23-foot cable makes it easy to accommodate nearly any parking layout, eliminating headaches during installation.

Delta’s vertical integration approach means it handles everything from design to manufacturing. But it doesn’t stop at hardware; the charger also connects to Delta’s IoT platform, offering remote diagnostics, predictive maintenance, and over-the-air updates. That hopefully means fewer disruptions and smoother operations for fleet managers and EV users.

Used EV prices fell 40%, and buyers are searching like never before

Used EV prices fell 40%, and buyers are searching like never before

Used EVs

More car buyers are hunting for used EVs – CarMax says searches filtered by “electric vehicle” have nearly doubled since January 2022.

CarMax saw EV searches surge in March 2022 and again in June 2024. The first spike lined up with the gas price shock after Russia invaded Ukraine, and the second came right as the Biden administration rolled out its $4,000 federal tax credit for used EVs.

The online used car marketplace’s Spring 2025 Electric Vehicle Consumer Report shows just how far used EV prices have tumbled, down over 40% between January 2022 and February 2025. By comparison, prices for gas cars, hybrids, and plug-in hybrids only slipped about 12% over the same period.

For the third year running, the Tesla Model 3 and the Model Y were in the No. 1 and No. 2 slots, respectively, from September 1, 2024, to February 28, 2025. The Chevy Bolt jumped into third place from its previous spot at No. 7 in 2024 and 2023. The Ford F-150 Lightning (7) and the Rivian R1T (10) made the top 10 for the first time, while the Tesla Model S and the Audi e-tron dropped out. The Hyundai Ioniq 5 and Nissan Leaf were at Nos. 5 and 6, and the Volkswagen ID.4 (4), Nissan LEAF (6), and the Ford Mustang Mach-E (9) made the list for the third year in a row.

What people are trading in

For the first time ever, more people are ditching sedans and coupes for EVs than SUVs. CarMax says sedans and coupes made up 44% of all EV trade-ins, up from 36% in 2024 and just 29% the year before. It’s a clear sign that the EV switch is picking up speed across more than just SUV drivers.

When customers traded in sedans for EVs during this report’s measurement period, the most common EVs they purchased were the Tesla Model 3, Tesla Model Y, and Chevy Bolt EUV. 

The top traded-in model for an EV at CarMax was the Tesla Model 3, and those who traded in a Model 3 usually went for a Model Y. The rest of the top five include the Honda Civic and Accord, the Nissan LEAF, and the Toyota Prius. The Ford F-150 truck, the top trade-in alongside the Accord in the 2024 report, dropped off the list.

Since this is CarMax’s report, it’s of course based on data sourced from its 250 stores across the US. In 2025, Oregon beat California to become the state with the highest percentage of EV sales compared to each state’s total sales at CarMax. California has previously held the top ranking since 2023. 

The West Coast continued to dominate when it came to used EV sales. California and Washington were in second and third place, respectively. Nevada and Arizona were fourth and sixth, while Utah and New Mexico (new to the top 10 list this year) held spots five and seven. On the East Coast, New York (10) appeared on the list for a second time, dropping two spots from No. 8 in 2024. 

The newcomers include Minnesota, which jumped 24 spots in a year to No. 8, and New Jersey, which moved up six slots to No. 9.

To limit power outages and make your home more resilient, consider going solar with a battery storage system. In order to find a trusted, reliable solar installer near you that offers competitive pricing, check out EnergySage, a free service that makes it easy for you to go solar.

EcoFlow RIVER 2 Pro Portable Power Station

EcoFlow launches multi-day flash offers on DELTA and RIVER power stations + EcoCredits purchase from $1

As we approach the end of EcoFlow’s ongoing Mega Sale through April 25, the brand has launched its last and longest flash sale offers, taking up to 48% off three units while also offering a major EcoCredits purchase opportunity. Alongside the return of the DELTA Pro 3 bundle we saw on Friday, you can now grab the RIVER 2 Pro Portable Power Station for $349 shipped. Normally fetching $599 outside of discounts, we first saw it come down to this rate during similar flash offers in the first phase of this sale. It’s returning as a second-chance opportunity for $250 in savings, giving you a solid traveling companion at the best rate we have tracked. It’s also beating out the pricing we’re seeing from Amazon by $10.

A more ample backup solution among the brand’s RIVER series, the RIVER 2 Pro is ideal for short-term needs at campsites, on road trips, and the like, providing you with a 768Wh LiFePO4 capacity to cover your essential devices and appliances. Through its eight output ports it can deliver up to 1,600W of power, with X-boost tech allowing it to “run 80% of home appliances.” It’s a great option for those who often make last-minute plans too, as plugging it into a wall outlet regains the battery in about 70 minutes, with it also having the options for USB-C and car port recharging, as well as a max 220W solar input, which can put it back at full in 3.5 hours to 4.5 hours in sunny conditions.

EcoFlow’s other flash sale offers ending April 25:

EcoFlow’s massive lineup of Mega Sale deals will only be lasting through April 25, complete with larger EcoCredit rewards, extra savings, and plenty of low prices – don’t miss it while it’s still around!

Aiper Surfer S2 Solar Pool Skimmer

Keep floating debris out of your pool with Aiper’s Surfer S2 solar skimmer back at its $320 low

Through its official Amazon storefront, Aiper is offering its latest Surfer S2 Solar Pool Skimmer for $319.98 shipped. Only on the market for a few months now, it usually carries a $540 price tag, which we first saw drop to this same rate at the top of February, which repeated last month in Amazon’s Big Spring Sale, and has otherwise kept between $340 and $400. You can pick one up while the $220 in savings last for your pool at the lowest price we have tracked, with the price also matching direct from Aiper’s website.

Building upon the success of its predecessor, Aiper’s second-generation Surfer S2 pool skimmer has been upgraded with features like the DebrisGuard anti-leak design, an improved brushless motor, an expanded suction inlet, and a 150-micron filtration system – all to provide better performance when collecting small and large debris alike from your pool’s surface. It’s also been given a larger battery that ramps up its runtime to 35 hours, with recharging available through the onboard solar panel for sunny days or its DC adapter as a backup option.

Working alongside the brand’s algorithms, it’s been equipped with dual dToF sensors to improve its obstacle avoidance – plus, there are even four retractable anti-standing columns to keep it from getting stuck on pool steps as it works. Should the columns fail to impede any such situations, the programming here knows to use its automatic self-rescue capabilities to get it back into the water to continue on its routines. There are the usual smart controls through the companion app that you’d expect, allowing you to monitor and adjust settings with the added bonus of being able to manually steer it.

Be sure to also check out the ongoing discounts across Aiper’s robotic pool cleaners that work right alongside the above pool skimmer to keep your pool clear and swim-ready, as well as the first discount we’re seeing on the new HydroComm 24/7 Smart Pool Monitor that provides 5-in-1 testing for your pool’s pH, ORP, EC, TDS, and temperature, as well as coming solar-powered.

Greenworks 40V 12-inch Cordless Electric Chainsaw

Expand your arsenal with this 2nd-gen Greenworks 40V 12-inch cordless chainsaw at $128

Amazon is offering the 2nd generation Greenworks 40V 12-inch Cordless Compact Chainsaw for $127.99 shipped. Coming down from its usual $170 price tag, discounts have been repeating to this same rate throughout the months since July of last year, with things before then only having gone as low as $120. Today’s deal is a 25% markdown off the going rate, saving you $42 while equipping your arsenal with the latest of the brand’s 12-inch compact chainsaws.

Coming in a more compact form, this 40V Greenworks chainsaw makes a reliable companion for firewood needs at home or while camping, as well as storm cleanup with hurricane season on the horizon. Powered by the included 2.0Ah battery, it sports a 12-inch bar and chain with an auto-oiler to ensure everything remains lubricated and running smoothly, delivering up to 50 cuts on a single charge. It weighs in at just six pounds, making it easy to operate for most users, complete with a safety lock and push-button start to save you time and energy over the frustrations caused by pull-strings.
