If you’ve read our cargo e-bike shopper’s guide, you may be well on your way to owning a new ride. Now comes the fun part.

Part of the joy of diving into a new hobby is researching and acquiring the necessary (and less-than-necessary) stuff. And cycling (or, for the casual or transportation-first rider, “riding bikes”) is no different—there are hundreds of ways to stock up on talismanic, Internet-cool parts and accessories that you may or may not need.

That’s not necessarily a bad thing! And you can even get creative—PC case LEDs serve the same function as a very specific Japanese reflective triangle that hangs from your saddle. But let’s start with the strictly necessary.

This article is aimed at the fully beginner cyclist, but I invite the experienced cyclists among us to fill the comments with anything I’ve missed. If this is your first run at owning a bike that gets ridden frequently, the below is a good starting point to keep you (and your cargo) safe—and your bike running.

First thing’s first: Safety stuff

Helmets

I once was asked by another cargo bike dad, “Are people wearing helmets on these? Is that uncool?”

“You’re already riding the uncoolest bike on earth—buy a helmet,” I told him.

For the most part, any helmet you pick up at a big box store or your local bike shop will do a perfectly fine job keeping your brains inside your skull. Even so, the goodly nerds over at Virginia Tech have partnered with the Insurance Institute for Highways Safety (IIHS) to rate 238 bike helmets using the STAR evaluation system. Sort by your use case and find something within your budget, but I’ve found that something in the $70–$100 range is more than adequate—any less and you’re sacrificing comfort, and any more and you won’t notice the difference. Save your cash.

Giro, Bell, Smith, POC, and Kask are all reputable brands with a wide range of shapes to fit bulbous and diminutive noggins alike.

Additionally, helmets are not “buy it for life” items—manufacturers recommend replacing them every four to five years because the foam and glues degrade with sun exposure. So there’s a built-in upgrade cycle on that one.

Lights

Many cargo e-bikes come with front and rear lights prewired into the electric system. If you opted for an acoustic bike, you’ll want to get some high-lumen visibility from dedicated bike lights (extra bike nerd bonus points for a dynamo system). Front and rear lights can be as cheap as you need or as expensive as you want. Depending on the brands your local bike shop carries, you will find attractive options from Bontraeger, Lezyne, and Knog. Just make sure whatever you’re buying is USB-rechargeable and has the appropriate mounts to fit your bike.

Additionally, you can go full Fast and the Furious and get nuts with cheap, adhesive-backed LEDs for fun and safety. I’ve seen light masts on the back of longtails, and I have my Long John blinged out with LEDs that pulse to music. This is 82 percent for the enjoyment of other bike parents.

A minimalist’s mobile toolkit

You will inevitably blow a tire on the side of the road, or something will rattle loose while your kid is screaming at you. With this in mind, I always have an everything-I-need kit in a zip-top bag in my work backpack. Some version of this assemblage lives on every bike I own in its own seat bag, but on my cargo bike, it’s split between the pockets of the atrociously expensive but very well thought-out Fahrer Panel Bags. This kit includes:

A pocket pump

Lezyne is a ubiquitous name in bike accessories, and for good reason. I’ve had the previous version of their Pocket Drive mini pump for the better part of a decade, and it shows no sign of stopping. What sets this pump apart is the retractable reversible tube that connects to your air valve, providing some necessary flexibility as you angrily pump up a tire on the side of the road. I don’t mess with CO2 canisters because I’ve had too many inflators explode due to user error, and they’re not recommended for tubeless systems, which are starting to be far more common.

If you spend any amount of time on bike Instagram and YouTube, you’ve seen pocketable USB-rechargeable air compressors made to replace manual pumps. We haven’t tested any of the most common models yet, but these could be a solid solution if your budget outweighs your desire to be stuck on the side of the road.

A multi-tool

Depending on the style and vintage of your ride, you’ll have at least two to three different-sized bolts or connectors throughout the frame. If you have thru-axle wheels, you may need a 6 mm hex key to remove them in the event of a flat. Crank Brothers makes what I consider to be the most handsome, no-nonsense multi-tools on the market. They have tools in multiple configurations, allowing you to select the sizes that best apply to your gear—no more, no less.

Tube + patch kit

As long as you’re not counting grams, the brand of bike tube you use does not matter. Make sure it’s the right size for your wheel and tire combo and that it has the correct inflator valve (there are two styles: Presta and Schrader, with the former being more popular for bikes you’d buy at your local shop). Just go into your local bike shop and buy a bunch and keep them for when you need ’em.

The Park Tool patch kit has vulcanization glue included (I’d recommend avoiding sticker-style patches)—they’re great and cheap, and there’s no excuse for excluding them from your kit. Park Tool makes some really nice bike-specific tools, and they produce This Old House-quality bike repair tutorials hosted by the GOAT Calvin Jones. In the event of a single failure, many riders find it sensible to simply swap the tube and save the patching for when they’re back at their workbench.

With that said, because of their weight and potentially complicated drivetrains, it can be a bit of a pain to get wheels out of a cargo bike to change a tire, so it’s best to practice at home.

A big lock

If you’re regularly locking up outside an office or running errands, you’re going to need to buy (and learn to appropriately use) a lock to protect your investment. I’ve been a happy owner of a few Kryptonite U-Locks over the years, but even these beefy bois are easily defeated by a cordless angle grinder and a few minutes of effort. These days, there are u-locks from Abus, Hiplok, and LiteLok with grinder-resistant coatings that are eye-wateringly expensive, but if your bike costs as much as half of a used Honda Civic, they’re absolutely worth it.

Thing retention

Though you may not always carry stuff, it’s a good idea to be prepared for the day when your grocery run gets out of hand. A small bag with a net, small cam straps, and various sizes of bungee cords has saved my bacon more than once. Looking for a fun gift for the bike parent in your life? Overengineered, beautifully finished cam buckles from Austere Manufacturing are the answer.

Tot totage

Depending on whether we’re on an all-day adventure or just running down to school, I have a rotating inventory of stuff that gets thrown into the front of my bike with my daughter, including:

  • An old UE Wonderboom on a carabiner bumping Frozen club remixes
  • A small bag with snacks and water that goes into a netted area ahead of her feet

And even if it’s not particularly cool, I like to pack a camping blanket like a Rumpl. By the time we’re on our way home, she is invariably tired and wants a place to lay her little helmeted head.

Floor pump

When I first started riding, it didn’t occur to me that one should check their tire pressure before every ride. You don’t have to do this if your tires consistently maintain pressure day-to-day, but I’m a big boy, and it behooves me to call this out. That little pump I recommended above? You don’t want to be using that every day. No, you want what’s called a floor pump.

Silca makes several swervy versions ranging from $150 all the way up to $495. With that said, I’ve had the Lezyne Sport Floor Drive for over 10 years, and I can’t imagine not having it for another 20. Mine has a wood handle, which has taken on some patina and lends a more luxurious feel, and most importantly, it’s totally user-serviceable. This spring, I regreased the seals and changed out the o-rings without any special tools—just a quick trip to the plumbing store. I was also able to upgrade the filler chuck to Lezyne’s new right-angle ABS 1.0 chuck.

The Lezyne Sport Floor Drive 3.5.

No matter what floor pump you go for, at the very least, you’ll want to get one with a pressure gauge. Important tip: Do not just fill your tires to the max pressure on the side of the tire. This will make for an uncomfortable ride, and depending on how fancy of a wheelset you have, it could blow the tire right off the rim. Start with around 80 PSI with 700×28 tires on normal city roads and adjust from there. The days of busting your back at 100 PSI are over, gang.

Hex wrenches

Even if you don’t plan on wrenching on your own bike, it’s handy to have the right tools for making minor fit adjustments and removing your wheels to fix flats. The most commonly used bolts on bikes are metric hex bolts, with Torx bolts used on high-end gear and some small components. A set of Bondhus ball-end Allen wrenches will handle 99 percent of what you need, though fancy German tool manufacturer Wera makes some legitimately drool-worthy wrenches.

If you have blessed your bike with carbon bits (or just want the peace of mind that you’ve cranked down those bolts to the appropriate spec), you may want to pick up a torque wrench. They come in a few flavors geared at the low-torque specs of bikes, in ascending price points and user-friendliness: beam-type, adjustable torque drivers, and ratcheting click wrenches. All should be calibrated at some point, but each comes with its own pros and cons.

Keep in mind that overtightening is just as bad as undertightening because you can crack the component or shear the bolt head off. It happens to the best of us! (Usually after having said, “I don’t feel like grabbing the torque wrench” and just making the clicking sound with your mouth).

Lube

Keeping your chain (fairly) clean and (appropriately) lubricated will extend its life and prolong the life of the rest of your drivetrain. You’ll need to replace the chain once it becomes too worn out, and then every second chain, you’ll want to replace your cassette (the gears). Depending on how well you’ve cared for it, how wet your surroundings are, and how often you’re riding, an 11-speed chain can last anywhere from 1,000 to 1,500 miles, but your mileage may vary.

You can get the max mileage out of your drivetrain by periodically wiping down your chain with an old T-shirt or microfiber towel and reapplying chain lube every 200–300 miles, or counterintuitively, more frequently if you ride less frequently. Your local shop can recommend the lube that best suits your climate and riding environment, but I’m a big fan of Rock’n’Roll Extreme chain lube for my more-or-less dry Northern California rides. The best advice I’ve gotten is that it doesn’t matter what chain lube you use as long as it’s on the chain.

Also, do not use WD-40. That is not a lubricant.

That’s it! There may be a few more items you’ll want to add over time, but this list should give you a great start. Get out there and get riding—and enjoy the hours of further research this article has inevitably prompted.

Fitness app Strava is tightening third-party access to user data

AI, while having potential, “must be handled responsibly and with a firm focus on user control,” and third-party developers may not take “such a deliberate approach,” Strava wrote. And the firm expects the API changes will “affect only a small fraction (less than 0.1 percent) of the applications on the Strava platform” and that “the overwhelming majority of existing use cases are still allowed,” including coaching platforms “focused on providing feedback to users.”

Ars has contacted Strava and will update this post if we receive a response.

DC Rainmaker’s post about Strava’s changes points out that while the simplest workaround for apps would be to take fitness data directly from users, that’s not how fitness devices work. Other than “a Garmin or other big-name device with a proper and well-documented” API, most devices default to Strava as a way to get training data to other apps, wrote Ray Maker, the blogger behind the DC Rainmaker alias.

Beyond day-to-day fitness data, Strava’s API agreement now states more precisely that an app cannot process a user’s Strava data “in an aggregated or de-identified manner” for the purposes of “analytics, analyses, customer insights generation,” or similar uses. Maker writes that the training apps he contacted had been “completely broadsided” by the API shift, having been given 30 days’ notice to change their apps.

Strava notes in a post on its forum in the Developers & API section that, per its guidelines, “posts requesting or attempting to have Strava revert business decisions will not be permitted.”

The Trek Checkpoint SL 7 AXS Gen 3 may be the perfect gravel bike

As I followed a friend down a flow-y, undulating single-track trail, I started laughing. Unlike my mountain bike-riding companion, I was on a gravel bike, the new Trek Checkpoint SL 7 AXS Gen 3. You might be wondering why a review of a gravel bike is starting with such a ride. The answer is simple—the Checkpoint had excelled everywhere else I rode it, so I was curious to see how it would fare on a non-technical MTB track. Amazingly well, as it turns out.

Unlike every other bike Ars has reviewed to this point, the Checkpoint SL 7 Gen 3 has no battery and no motor—there’s no e- in this bike. As is the case with our other bike reviews, sometimes we ask for a specific model, but manufacturers tend to contact us when we’ve already got a garage full of bikes we’ve not finished the reviews for (there are currently 12 bikes in my garage, some of which belong to other family members).

Launched in 2018, the Checkpoint is Trek’s gravel-centric bike. For 2025, Trek has split its gravel lineup into the third-generation Checkpoint Trek and the Checkmate SLR 9 AXS. The latter features a lighter-weight frame, a power meter, and SRAM’s new Red XPLR groupset. Selling for $11,999, the Checkmate is a gravel racer. Priced several thousand less at $5,699, the Checkpoint SL 7 AXS is now Trek’s top gravel bike for those looking for a fun day out on the trails.

With the Gen 3 Checkpoint, Trek has added mounts all over the frame, tweaked the geometry to make it more comfortable for long rides, improved ride comfort by reworking the rear IsoSpeed decoupler (which softens the bumpiness from rough trails and pavement), and increased the tire clearance to 50 mm (42 mm with fenders). Trek uses three different types of carbon on its drop handlebar bikes. The top-of-the-line OCLV 900 shows up on the racing-focused Madone road bike, while the OCLV 800 is used in the Domane endurance bike lineup as well as the Checkmate. The SL 7 uses Trek’s 500 Series OCLV carbon, and the bike weighs in at 19.85 lb (9.0 kg)—about 100 g heavier than the Gen 2. The drivetrain comes from SRAM, with a SRAM Force XPLR AXS D2 groupset.

Trek CarBack bike radar lets you know when cars are approaching

“Car back!”

If you’ve ever been on a group bike ride, you’ve no doubt heard these two words shouted by a nearby rider. It’s also the name of Trek’s new bike radar.

For safety-conscious cyclists, bike radars have been a game-changer. Usually mounted on the seat post, the radar units alert cyclists to cars approaching from behind. While they will work on any bike on any road, bike radar is most useful in suburban and rural settings. After all, if you’re doing some urban bike commuting, you’ll just assume cars are behind you because that’s how it is. But on more open roads with higher speed limits or free-flowing traffic, bike radars are fantastic.

While a handful of companies make them, the Garmin Varia is the best-known and most popular option. The Varia is so popular that it is nearing the proprietary eponym status of Kleenex and Taser among cyclists. Trek hopes to change that with its new CarBack bike radar.

Like other bike radars, the CarBack can be used with either a cycling computer or your smartphone. Mounted either on a seat post or the back of a Bontrager saddle, the CarBack can detect vehicles approaching from as far away as 150 meters, beeping at you once one is in its range.

The CarBack plays just as nicely with Garmin bike computers as the Varia does. When a car comes within range, your bike computer will chirp, the edges of the screen turn orange, and a dot showing the car’s relative position travels up the right side of the screen—exactly the same as riding with a Varia.

Speaking of the Varia, there are three significant differences between it and the CarBack. The first is the effective range, 140 meters for the Varia versus the CarBack’s 150 meters. While riding, I didn’t have the feeling that I was getting alerts sooner. But testing on a busy street demonstrated that the CarBack does have at least a few more meters of range than the Varia.

The world’s toughest race starts Saturday, and it’s delightfully hard to call this year

Is it Saturday yet? —

Setting the stage for what could be a wild ride across France.

Most readers probably did not anticipate seeing a Tour de France preview on Ars Technica, but here we are. Cycling is a huge passion of mine and several other staffers, and this year, a ton of intrigue surrounds the race, which has a fantastic route. So we’re here to spread Tour fever.

The three-week race starts Saturday, paradoxically in the Italian region of Tuscany. Usually, there is a dominant rider, or at most two, and a clear sense of who is likely to win the demanding race. But this year, due to rider schedules, a terrible crash in early April, and new contenders, there is more uncertainty than usual. A solid case could be made for at least four riders to win this year’s Tour de France.

For people who aren’t fans of pro road cycling—which has to be at least 99 percent of the United States—there’s a great series on Netflix called Unchained to help get you up to speed. The second season, just released, covers last year’s Tour de France and introduces you to most of the protagonists in the forthcoming edition. If this article sparks your interest, I recommend checking it out.

Anyway, for those who are cycling curious, I want to set the stage for this year’s race by saying a little bit about the four main contenders, from most likely to least likely to win, and provide some of the backstory to what could very well be a dramatic race this year.

Tadej Pogačar

Tadej Pogacar of Slovenia and UAE Team Emirates won the Giro d'Italia in May.

Pogačar burst onto the scene in 2019 at the very young age of 20 by finishing third in the Vuelta a España, one of the three grand tours of cycling. He then went on to win the 2020 and 2021 Tours de France, first by surprising fellow countryman Primož Roglič (more on him below) in 2020 and then utterly dominating in 2021. Given his youth, it seemed he would be the premiere grand tour competitor for the next decade.

But then another slightly older rider, a teammate of Roglič’s named Jonas Vingegaard, emerged in 2022 and won the next two races. Last year, in fact, Vingegaard cracked Pogačar by 7 minutes and 29 seconds in the Tour, a huge winning margin, especially for two riders of relatively close talent. This established Vingegaard as the alpha male of grand tour cyclists, having proven himself a better climber and time trialist than Pogačar, especially in the highest and hardest stages.

So this year, Pogačar decided to change up his strategy. Instead of focusing on the Tour de France, Pogačar participated in the first grand tour of the season, the Giro d’Italia, which occurred in May. He likely did so for a couple of reasons. First of all, he almost certainly received a generous appearance fee from the Italian organizers. And secondly, riding the Giro would give him a ready excuse for not beating Vingegaard in France.

Why is this? Because there are just five weeks between the end of the Giro and the start of the Tour. So if a rider peaks for the Giro and exerts himself in winning the race, it is generally thought that he can’t arrive at the Tour in winning form. He will be a few percent off, not having ideal preparation.

Predictably, Pogačar smashed the lesser competition at the Giro and won the race by 9 minutes and 56 seconds. Because he was so far ahead, he was able to take the final week of the race a bit easier. The general thinking in the cycling community is that Pogačar is arriving at the Tour in excellent but not peak form. But given everything else that has happened so far this season, the bettors believe that will be enough for him to win. Maybe.
