Dainese develops D-air intelligent airbag system to keep motorcyclists safer

dainese d air system improves safety dair3

The progression of sport is often bolstered by the development of safety equipment. Allowing athletes to forgo that inner voice telling them to stop or slow down — and instead push harder — is what breaks records and pushes limits, and the Dainese D-air system is pushing the current limits of safety technology.

The D-air system is essentially an intelligent airbag integrated into a vest, jacket, or full leather suit. What makes the system intelligent is the load of electronics buried within the back protector. Consisting of three accelerometers and gyroscopes, GPS, 4 GB of internal memory, and a lithium battery, the D-air system ingests information quicker than any athlete. Once the brain detects an anomaly — decided by Dainese’s patented triggering algorithm — a pneumatic gas generator fills the airbag in 30 to 45 milliseconds without any human input — a blink takes 300 to 400 milliseconds.

Dainese started researching airbags for its motorcycle racing teams back in 2000 and has since undergone a variety of changes. Now, consumers can purchase the same tech used by the world’s top athletes and it’s designed to suit various sports and motorcycle riding styles. Dainese even adapted the D-air to work for snow skiing as well as street motorcycling use, with development currently underway for competitive sailing.


What allows the adaptation for multiple sports is Dainese’s triggering algorithm. Around 800 times per second, the algorithm takes a massive amount of data conveyed by the sensors and makes determinations on whether or not it should deploy. Having this sort of computing power allows Dainese to adjust its trigger points based on the needs of the sport.

In addition to safety, users also have access to the well of amassed data. Dainese’s Peter Bacon spoke to the future of the D-air system and the eventual integration of more user-friendly ways of analyzing rider data. This could mean an iPhone app down the road, but such development is still a few years in the making. The current data platform that’s available is called 2D and (allegedly) takes a degree in mechanical engineering to decipher — or so we were told.

While the algorithm may consist of code that’s easily altered, the impacts felt by athletes are not. Dainese improves their devotion to rider safety by altering its airbag layout based on the impacts most common for each sport. Collarbone collisions are commonplace in motorcycle racing while on the street, more chest protection is warranted. In skiing, special attention is given to the back.

All of Dainese’s D-air systems utilize its patented 3D airbag. What makes the 3D airbag special is its microfilament found throughout the interior of the bag, ensuring uniform inflation of 5 centimeters throughout. This uniform inflation is what allows the D-air to provide an 85 percent reduction in transferred force (3 kilonewtons) over traditional protection (23 to 24 kilonewtons).

While safety stats may never be the sexiest thing to talk about, walking away from a serious crash will always be a story that impresses. The D-air for street motorcycling is coming soon, with the Mugello R full suit coming later this year. However, the D-air Ski’s timeline for consumer use is still under development.

I turned my van into an office with a battery-powered AC and heat pump
An EcoFlow Wave 2 air conditioner and heat pump inside a Mitsubishi Delica van.

Like a lot of remote workers, I know I’m lucky to be able to work from home. I have a home office with a comfy leather chair, a skylight, and an oversized doofus of a dog, Marty, who reclines adorably on the couch behind me for Zoom meetings. But I’d also be lying if I didn’t admit I go a little stir crazy from time to time, yearning to work from somewhere other than the same place I eat, sleep, and relax.

How about a van? I bought my 1990 Mitsubishi Delica for camping, but it always seemed like it could serve as a mobile office with a view, if not for one critical shortcoming: For nine months out of the year in Portland, it’s too cold, and for the other three, it’s too hot. Without adding thousands of dollars for a battery power system, my best bet was heavy socks and gloves. But EcoFlow gave me a glimmer of hope at CES 2023 when I spotted the EcoFlow Wave 2. With an onboard battery, it promised to heat or cool anywhere, no external power system needed.

I was wrong. E-bikes are so practical, they’re a transit cheat code
An Aventon Level 2 ebike sits outside a grocery store.

Confession: Despite loving both bikes and gadgets, e-bikes never excited me. Compared to my bicycle, e-bikes seemed unfair. Compared to my motorcycle, they seemed slow. Compared to my car, they seemed impractical.

But with $1,500 federal e-bike rebates potentially on the horizon at part of E-Bike Act, I decided it was past time to reconsider. Not just because 30% off would make them way more accessible, but because the entire idea that e-bikes could be worthy of a rebate changed the way I looked at them: less as toys, more as transit. Had I written off an entire way of getting around because I was looking at it the wrong way?

It wasn't too long ago that e-bikes were a rare sight, but all of that has changed, and rightfully so. Electric bikes are all over the road these days, and there are many brands either venturing into the technology, to launch their own versions of the sustainable transportation option or reiterating existing and traditional designs. From Aventon to Schwinn, or RadPower to Momentum, with so many opportunities, the prevailing question is, where do you go to find the best deals and the best information about these brands and their e-bike models? The answer is Upway, the number one certified electric bike provider and an official partner to many of the aforementioned brands.

What is Upway, exactly? It's a marketplace, specializing in e-bikes, featuring an inventory that's sourced from some of the best brands in the world. There are American brands -- like Specialized, Cannondale, and RadPower -- and European brands -- like Riese, Muller, and VanMoof. The best part is the discounts, offering up to 60% off retail, for a plethora of brands. Upway is on a mission to make sustainable mobility affordable for everyone. It's also one of the best places to go for a new or pre-owned e-bike, and here's why:
