Cowboy, maker of some of our favorite pedal-assisted electric bikes, is back with two new models for 2021. The Cowboy 4 is a complete overhaul to last year’s Cowboy 3 while the Cowboy 4 ST features the company’s first step-through frame. Both bikes benefit from a new powertrain with 50 percent more torque than last year’s C3 as well as a new integrated “cockpit” with Quadlock mount that wirelessly charges your phone as you ride. But that’s just a start to the bevy of tweaks both big and small that Cowboy hopes will justify a price tag of €2,490 / £2,290 (about $3,000 USD) when the bikes ship in September.

I had a chance to ride near final pre-production versions of the Cowboy 4 and Cowboy 4 ST alongside Adrien Roose, co-founder and CEO of Brussels-based Cowboy. While the two bikes share the same specs, the rides couldn’t be anymore different.

“We’ve stayed true to our initial vision of providing a better alternative to the car — in form and function — and with the Cowboy 4 it’s a shift we will accelerate and lead,” said Roose in a press statement.

The fourth-generation C4 maintains the same sporty riding position and ultra-responsive steering as every Cowboy before it. But this year’s model has a redesigned 250W rear-hub motor that remains silent as it assists riders up to a max speed of 25km/h (15.5mph), even though it’s smaller and produces noticeably more torque. The bump from 30Nm to 45Nm of torque is apparent on the first downstroke, with the lightest of touches propelling the slightly heavier 18.9kg / 41.67-pound e-bike forward with enough gusto to help smooth out hills. 

The C4 ST has a lower saddle and higher grips that put the rider into a more upright position. That coupled with a lower gear ratio (2.71 on the C4 ST vs. 2.85 on the C4) makes the ride feel more relaxed despite having the same motor and Gates Carbon belt drive as its brother. The C4 ST is the model you buy for long, lazy commutes with a laptop bag, or for anyone who won’t fit the C4’s taller frame.

One of the most intuitive pedal-assisted rides on the road

The C4 e-bikes, like their predecessors, offer only a single power setting with no throttle and no extra gears. They rely on a torque sensor to adjust the power delivery as needed, which has traditionally resulted in one of the most intuitive pedal-assisted rides on the road.

Cowboy refers to the Quadlock mount with integrated wireless charging unit as the “cockpit.” It can charge your phone at up to 15W from the e-bike’s removable 360Wh battery, but requires a Quadlock-compatible case that must be purchased separately for about €29 / £29. Although the cockpit is bulky enough to fit another battery, the space is mostly empty I’m told, providing a wide base for the wireless coils and access to the frame to run brake cables through. 

Cowboy’s redesigned app.

The Cowboy apps for iOS and Android have also been totally redesigned with an emphasis on health and fitness in addition to navigation, with many new features rooted in game design theory. “What we’re trying to achieve is some weird mix between Strava, Peloton, and Pokémon Go,” said Roose, “simply to encourage people to bike more.”

The fourth-generation Cowboy 4 also improves upon the Cowboy 3 in a number of other ways:

  • The C4 is redesigned down to the component level, making one of the best looking e-bikes look even more cohesive and sleek. Cowboy says the C4 now features “200 custom-made parts” assembled by Flex in Hungry, including the motor and tires. The Selle Royal saddle, SunRace hydraulic brakes, and Gates drive are the notable outliers.
  • The €89 Cowboy mudguards are finally standard, which partially explains the added weight and price of the new e-bikes.
  • The C4 and C4 ST still don’t come with kickstands, but at least Cowboy now makes its own as a €29 / £29 add-on. It’s also making an optional rear rack priced at €99 / £99.

Cowboy doesn’t currently sell e-bikes in the US, but that will change next year, according to Roose, who’s particularly bullish after hearing President Biden’s plans to cut CO2 emissions. “Our growth, and the growth of the US e-bike market, is making a move for us quite appealing and we want to jump,” said Roose. “We’re talking the next 12 months.” 


For Europeans, the €2,490 / £2,290 purchase price for a Cowboy 4 / 4 ST includes theft and crash detection, and free on-demand mobile repairs available nationwide in Belgium, The Netherlands, Germany, France, Austria, Luxembourg, the UK, and in select cities in Spain and Italy. Cowboy also touts its 94.4 percent customer satisfaction rate, noting that owners get replies to support requests within six minutes, on average. A little poke at e-bike rival VanMoof, perhaps, which struggled to support buyers of its S3 and X3 e-bikes as sales ramped up during the pandemic.

The C4 and C4 ST are available in three colors: black, khaki (greenish), and sand (off-whiteish). Test rides will begin in July before the bikes start shipping in September to Austria, Belgium, France, Germany, Italy, Luxembourg, the Netherlands, Spain, and the UK. Preorders begin today after a €100 / £100 deposit.

The Cowboy 3 is also being reduced to €2,190 today and now comes standard with mudguards. That’s a price drop of €189 compared to the same e-bike purchased last year.

Looking for something to do this weekend?

Why not hang out on the couch playing video games and watching TV. It’s a good time for it, with intriguing recent releases like Return to Monkey Island, Session: Skate Sim, and the Star Wars spinoff Andor. Or you could check out some of the new anime on Netflix, including Thermae Romae Novae (pictured below), which is my personal favorite time-traveling story about bathing.

Has the Windows 11 2022 Update made your gaming PC stutter?

Nvidia GPU owners have been complaining of stuttering and poor frame rates with the latest Windows 11 update, but thankfully there’s a fix. Nvidia has identified an issue with its GeForce Experience overlay and the Windows 11 2022 Update (22H2). A fix is available in beta from Nvidia’s website.

If you’re using crash detection on the iPhone 14, invest in a really good phone mount.

Motorcycle owner Douglas Sonders has a cautionary tale in Jalopnik today about the iPhone 14’s new crash detection feature. He was riding his LiveWire One motorcycle down the West Side Highway at about 60 mph when he hit a bump, causing his iPhone 14 Pro Max to fly off its handlebar mount. Soon after, his girlfriend and parents received text messages that he had been in a horrible accident, causing several hours of panic. The phone even called the police, all because it fell off the handlebars. All thanks to crash detection.

Riding a motorcycle is very dangerous, and the last thing anyone needs is to think their loved one was in a horrible crash when they weren’t. This is obviously an edge case, but it makes me wonder what other sort of false positives we see as more phones adopt this technology.

Ford is running out of its own Blue Oval badges.

Running out of semiconductors is one thing, but running out of your own iconic nameplates is just downright brutal. The Wall Street Journal reports badge and nameplate shortages are impacting the automaker's popular F-series pickup lineup, delaying deliveries and causing general chaos.

Some executives are even proposing a 3D printing workaround, but they didn’t feel like the substitutes would clear the bar. All in all, it's been a dreadful summer of supply chain setbacks for Ford, leading the company to reorganize its org chart to bring some sort of relief.

Once again, the US has fallen behind in transportation — call it the Bussí gap. A hole in our infrastructure, if you will.

Doing more with less (extravagant holiday parties).

Sundar Pichai addressed employees’ questions about Google’s spending changes at an all-hands this week, according to CNBC.

“Maybe you were planning on hiring six more people but maybe you are going to have to do with four and how are you going to make that happen?” Pichai sent a memo to workers in July about a hiring slowdown.

In the all-hands, Google’s head of finance also asked staff to try not to go “over the top” for holiday parties.

Insiders made the most money off of Helium’s “People’s Network.”

Remember Helium, which was touted by The New York Times in an article entitled “Maybe There’s a Use for Crypto After All?” Not only was the company misleading people about who used it — Salesforce and Lime weren’t using it, despite what Helium said on its site — Helium disproportionately enriched insiders, Forbes reports.

Nvidia’s latest AI model generates endless 3D models.

Need to fill your video game, VR world, or project render with 3D chaff? Nvidia’s latest AI model could help. Trained on 2D images, it can churn out customizable 3D objects ready to import and tweak.

The model seems rudimentary (the renders aren’t amazing quality and seem limited in their variety), but generative AI models like this are only going to improve, speeding up work for all sorts of creative types.
