‘Modular Cycling Helmet with a full-face attachment for motorbikes’ secures Silver at the YD x KeyShot Design Challenge

Among hundreds of entries for the YD x KeyShot Design Challenge that asked participants to redesign the Envoy Helmet to make it safer,
António Martins’ redesign turned the bicycle helmet into a versatile piece of headgear that could even offer full-face protection while riding motorcycles.

“To make ENVOY Helmet safer, I designed a removable chin protector along with a practical snap system. Its clean design makes the chin protector look like part of the helmet”, said Martins about his Silver Award-winning design.

It makes a world of sense, because people shouldn’t have to buy two separate helmets for bicycles and motorbikes. Martins’ elegant modular design allows you to have both helmets within one product. The redesigned Envoy proposes having a separate, detachable chin-protector that can easily and securely be snapped in place using tabs on either side of the helmet. Just attach the chin protector and the Envoy goes from being a cycling helmet to something perfect for motorbiking, quad-biking, and even snowmobiling in.

Unanimously declared the Silver Winner by the YD x KeyShot Design Challenge Jury Panel, António also wins a pair of AirPods Pro along with a KeyShot HD Licence.

The Carol smart exercise bike is a $2,400 paradox

If you had the opportunity, would you pay more in order to use an exercise bike less frequently? That is, give or take, the sales pitch for Carol’s at-home spin bike. It’s the anti-Peloton, designed to be used for just 8 minutes and 40 seconds per workout. At the end of its standard program, it even tells you that you can go to the gym if you want to, rather than because you need to. But stealing back all of those hours from the capricious gods of exercise comes at a price: $2,395, plus $12 per month after the first three months. It’s up to you to decide if that eye-watering fee is worth swerving all of those cardio sessions.

Carol leverages the principles of Reduced Exertion, High Intensity Interval Training (REHIIT), a variation on the Tabata method of HIIT. Put simply, you’re asked to exercise at a very high intensity for a very short period of time, rather than a long period of time in a steady state. In this example, Carol says that its standard sub-nine-minute workout gives you the equivalent workout to a 45-minute jog. This involves you going all-out for 20 seconds, but then having the better part of three minutes to recover.

That 20-second frenzy is designed to deplete your body’s stores of glycogen and pushes the heart rate through the roof. The long recovery time is designed to reset your body, enabling you to grind out far more from your muscles than you would in a standard Tabata workout. And studies have shown that, at least in male participants, a six-week REHIIT program can improve their insulin resistance and oxygen consumption.

“One of the things I like about REHIIT is the long length of the recovery periods,” says Stuart Moore, trainer and owner of Wheel Fitness, a specialist cycling practice. “This enables people without a lot of experience to recover properly between bouts of hard work and then go again with another round.” He added that “all interval training can be useful,” but stressed that would-be adopters “should get the important checks with your doctor” before trying this sort of thing. “I’d prefer complete beginners to interval training try something more mild than modified versions of HIIT,” he said, “this could help with developing a base before delving into the more intense exercise later.”

Andrea Speir, co-founder and lead trainer at Speir Pilates, added that the psychological benefits on neophyte exercisers were crucial. “Because it spikes the heart rate and improves VO2 Max, cardiac output and boosts the metabolism [...] without being too strenuous,” she said. “It’s not as daunting to commit to it three-to-five times a week, which is where you really see great results,” she added.

History

It’s not often that a company founder announces that their product exists because of a BBC documentary, but Carol isn’t exactly a standard Silicon Valley story. Co-founder Ulrich Dempfle was a management consultant working with the UK’s National Health Service on behalf of firms like McKinsey and PWC. Part of his role was to look for ways to encourage people to exercise more, despite the fact they would often say they didn’t have enough time to become gym bunnies. It wasn’t until he watched 2012’s The Truth About Exercise that he became a convert to REHIIT.

The documentary was fronted by Dr. Michael Mosely, who is chiefly responsible for making intermittent fasting mainstream in the UK. One of Mosely’s gimmicks has always been to look for more efficient ways to feel healthy, and this was a love letter to REHIIT. Dempfle and his team contacted the academics whose research was featured in order to get a look at their equipment. Dempfle explained that the bikes featured had their intensity controlled by one of the academics while a person exercised on them, and that the price was astronomical. It was here that the idea of building an affordable REHIIT bike was more or less born. In fact, Carol would wind up being featured in a Mosley’s 2018 follow-up documentary, The Truth About Getting Fit, albeit not named because of the BBC’s rules against product placement.

Bike

At first glance, Carol could be mistaken for pretty much any at-home exercise bike. It has a very large, rear-slung flywheel and a beefy drive unit, which houses the system to electronically control the resistance, the secret sauce behind the REHIIT program. A pair of short handles with the customary heart rate-monitoring electrodes sit below the display housing, which holds a 10.1-inch screen. The seat height and distance is adjustable, as well as the height of the handlebars, and there are toe cages and clips on the pedals, for pro cyclists.

After you’ve registered, you can then log in to the bike, which is a process you’ll have to do every time you want to use it. After the first attempt, you can just tap on your initials on a list of stored users, but there’s no way to stay logged in by default. Given how beefy the bike is, and that it’s designed for both at-home and professional use, I feel as if this makes it well-suited to offices and gyms, more so than people’s homes. You could easily see this in the corner of a small business, with staff members getting their 10 minutes each day as they take a break from their work.

Display

When it comes to screens, there are two schools of thought dominating the at-home fitness market. Peloton’s ubiquity means that consumers may soon expect all machines to have a glossy, massive HD display as the default. Companies like Wattbike, Concept2 and others, however, are happy pushing out machines that still leverage old-school LCD head units. (On a personal note, the Polar View offered by the Wattbike PMB is one of the best training tools I’ve ever encountered).

Carol splits this difference by offering a 10.1-inch color touchscreen that offers the same sort of data you’d find on an LCD set, but cleaner and more colorful. The UI flashes an angry red when you hit the high intensity phase, and the visualizations showing your power output are great. A software update, too, came through during my review that has made the UI a lot cleaner and smoother than it was before. And, even better, you can use the display to live stream classes from Peloton’s own app, although you’ll need to subscribe to them separately.

Boot the bike up for the first time and you’ll be greeted by a Lenovo splash screen because Carol’s display is quite literally a Lenovo tablet in a housing. On paper, this is genius: An Android tablet should last longer, is more affordable and should be easier to replace than a custom solution. Plus, you can (and Carol does) leverage Google’s pre-built accessibility features for adjusting screen fonts and voice overs that it would take time and money to copy for little-to-no upside.

Not to mention that, because it is an Android tablet, you can run third-party apps through the Play Store, albeit only ones that have been sanctioned by Carol’s makers. So far, that’s just Peloton, but there’s no technical reason that your favorite fitness, or entertainment, app couldn’t wind up on this screen as well. But, for all of those positives, slamming an Android tablet onto a bike and calling it quits still feels a bit lackluster for a bike costing two thousand four hundred dollars.

Once you’ve answered the medical questionnaire, you have to go through six taster sessions for the bike to gauge your overall fitness level. After that point, you’re free to sample the delights that the bike has to offer, including four different REHIIT workouts. I pretty much stuck to the standard program — the reason anyone would buy a Carol bike — but there are other options available. This includes an Energiser ride, which offers shorter, 10-second sprints, as well as 15-minute or 25 minute Fat Burn program, with 30 or 60 sprints, respectively. You also get the option for a Free Ride, with power controlled by yourself, or an Endurance ride with the resistance slowly ramping up beyond your ability to cope with it.

Once you’ve chosen a program, you’re asked to choose from a series of generic audio options but, again, I was advised by the company’s representatives to stick with the default. (This was probably for the best, because the other options are essentially musak.) In it, a calm voiceover talks about how neanderthal man never jogged, they either walked slowly, or ran like their lives depended on it. At the same time, the on-screen coaching tells you to breathe in for four seconds, hold for a beat, and then exhale over six seconds, which is hard to coordinate if you’re bad at multitasking. All the while you’re asked to cycle at a very low level, never exceeding an output of 20 watts or so.

There’s a countdown timer on screen (and a timeline), so it’s not as if you’re not told when the sprints are about to begin. But the narration treats it more like a surprise, talking about the vista when, suddenly, she tells you that there’s a tiger leaping out at you!, and you have to pedal for your life. The screen turns red three seconds before the sprint begins, letting you spool up as you prepare to go hell for leather to escape your predator. Because the resistance is calibrated to your fitness level, it continues to go up after your initial burst of energy to ensure that you’re nicely wiped out by the end of the sprint. Hell, I found that I was flagging at the 10-second mark, and could never get back to my first output peak no matter what I tried.

You may scoff at the idea that biking for just 20 seconds can wipe you out and make any positive impact on your fitness. You begin to feel your legs go as your body suddenly starts to wuss out, and the final quarter of the sprints have you running on fumes. As effective exercises go, the system makes good upon its promises, and you need that long recovery time to restore any sense of humanity you may have had. The screen will graph your output (and compare it to your output on the second sprint, when you hit it) and let you see how far you’ve dropped between runs. Although the on-screen display’s promise that you won’t sweat is mostly true, it’s not entirely fair for sweaty, sweaty boys like me.

Wrap-up

In the period in which I was using Carol, I think my fitness did improve, as did my mood when I was trying to complete one of these more or less every single day. (The bike repeatedly advises you, as does its representatives, to only do a single sprint session in a 24 hour period and only three times a week to avoid injury.) You certainly start the day feeling more energized, and I can’t complain that this has eaten a big chunk of my day when it hasn’t.

But I’m finding myself hamstrung by the price, especially given the fact that it’s designed to do one job, one fitness program, to the exclusion of most others. Do I want to spend $2,399 plus an additional $12 a month on an appliance I’d use for 30 or 40 minutes a week? Yes, that’s less than you can spend on a Wattbike Atom or Peloton Bike+, but it’s still a lot. In that philistinic sense of knowing the cost of something but not its value, the numbers make my eyes water.

It’s a bike that does one thing, really, and it does it well, but I feel in my gut that I’d have an easier time singing this thing’s praises if its price was just below the $2,000 mark. It’s a weird psychological barrier for sure, and maybe you’re scoffing at my imaginary parsimony. But as much as this thing is designed for a mainstream audience, right now, it’s priced at the level where only enthusiasts can buy it.

Bird unveils a $2,299 electric bike you can own

While Bird is mostly known for its rental scooters, it expanded its electric transportation offerings back in June when it introduced a bike-sharing service. Now, the company is giving those who want electric bikes of their own a new option to choose from: It has launched a new product called Bird Bike, which people can purchase right now for US$2,299. The electric bike has a Bafang rear hub motor with 50 miles of range and a 36-volt removable battery made of LG cells for easy charging.

In the UK and the European Union, owners will have access to 250 watts of continuous rated power in line with local regulations. Meanwhile, users in the US will have access to 500 watts of electric support. The bike has a pedal assist speed of 20 mph and has a thumb throttle, which can give riders an extra burst of acceleration to help them take on difficult inclines.

It's also equipped with an LCD display showing the rider's speed, battery charge, assist information and other details. Other features include a commercial-grade aluminum alloy frame, puncture-resistant tires and Bluetooth connectivity with the Bird app, allowing riders to easily switch their vehicle lights on and off and to view their battery range and miles ridden.

The Bird Bike comes in two types: One has a step-through frame, while the other has a step over frame. It also comes in two colors, namely Stealth Black and Gravity Gray. Bird is selling limited quantities of the e-bike right now on its website, but it will be available more broadly from retailers in the US and Europe this fall.

Little Tikes made a Peloton-style stationary bike for kids

Young kids who see their folks on a Peloton bike and want to join in on workouts will soon have another way to do that. Little Tikes has created a smart stationary bike for children aged three to seven. It's called the Pelican Explore & Fit Cycle, which does not at all sound like "Peloton." Not one bit.

As with certain other connected stationary bikes, kids can cycle with the help of virtual trainers. They'll have access to trainer adventure videos that Little Tikes uploaded to YouTube. Youngsters can pretend they're cycling on a snowy mountain with a dinosaur buddy and ride over farmlands to see animals and practice the alphabet. They can also take a virtual trip into the woods on an adventure bike trail.

The handlebars and seat are adjustable. There's also a Bluetooth speaker so that kids can ride along to the beat of their favorite songs. The Pelican Explore & Fit Cycle will be available at Target next week.

This air pollution sucking bike wheel is the solution needed to provide clean breathing air!

Human inflicted air pollution is a nemesis for the planet, upsetting the balance of the ecosystem and contributing largely to the global warming woes. The problem has quickly escalated and is proving to be a major headache for nations worldwide. People are doing their bit by adopting emission-free modes of commuting – bicycles being the simplest and easiest ones to adopt right now, giving us all reason enough to make the switch from four-wheeled air-polluting vehicles. As an added bonus, they fit right in with the fitness regime for a healthy lifestyle. According to the European Cyclists’ Federation, “average bike emits 21g of CO2 per kilometer traveled – 5g for the bike’s manufacture and maintenance and 16g for the calories consumed, and subsequently burned, by the cyclist to power the pedals.” In comparison, a motor vehicle emits 271g of CO2 per passenger kilometer!

Taking a ride on the pedal-powered bike is an eco-friendly way of living but can it be bettered? According to industrial design graduate from London Southbank University, Kristen Tapping, it is possible. She has thought of an innovative way to turn the bike’s wheel into air pollution capturing device that purifies the air and releases it back into the environment. The award-winning invention christened Rolloe Roll Of Emissions, inspired by the highly air polluted streets of London, has to be one of the cleanest ways of commuting, especially in crowded cities. Kristen pondered the spinning movement of the bike’s wheel and its use as an air filter, just like a conventional household air filter does with the spinning motion. The mechanism works by pushing the polluted air inside the rim of the wheel which houses the filters. These filters are made up of the loofa sponge which is a washable and biodegradable HEPA filter that captures the large particulates and activated carbon which is proven for its properties to capture gas molecules and volatile organic compounds.

The innovative wheel is designed in a way to suck in the air through the central cavity and push clean air out through the fins. The more the biker pedals forward, the more particulates are captured. For now, the prototype developed by Kristen captures 0.665m³ of air per kilometer cycled. According to her if “10% of all London cyclists had one Rolloe installed on their bike, they would filter approximately 266,865m³ of air – 20 times the size of Trafalgar Square.” Kristen wants to improve her design and develop a rear-wheel which doubles those numbers. She is also working on 3D printing a portion of the three-spoke mag wheel and using weatherproof and sustainable material for the wheel. Rolloe is surely a wise step in the right direction and we can’t wait to see it become a part of our everyday life!
