Will this “AI rear-view mirror” enhance road safety for cyclists? Plus "performance-enhancing" sunscreen, ANOTHER cycling indicator, cyclist yells at cloud, white bib shorts and tech news from Shimano, Rapha, Trek + more

​It’s time to go through the top tech stories of the week and as usual, there's no shortage. Kicking things off with an Irish tech company’s “AI rear-view mirror”, an indicator for bikes and helmets from the set of Dragon’s Den, cycling sunscreen with some big claims, sunglasses from Mavic, and a collaboration between Pirelli and Santini delivering some white bib shorts. 

Can this “AI rear-view mirror” keep you safer on the road?

An Irish tech company is launching an AI-powered camera and app that provides a rear-view livestream to your handlebar-mounted phone and alerts you to vehicles approaching too closely. The Luna Oculus system also functions as a dashcam, capturing video evidence in the event of a near miss, and maps close passes so you can choose safer routes.

“We are on a mission to empower cyclists with the kinds of safety technologies already deployed in modern cars,” says Luna.

There’s a lot going on here, then, but at the heart of things is a compact, rear-mounted camera that connects to a smartphone app.

Luna Systems says, “The system functions as an AI-powered ‘rear view mirror’, alerting riders when rear vehicles approach too closely. The camera connects to a smartphone via Wifi and provides an app interface with a rear-view livestream with a simple and non-distracting visual warning overlay.

“The app also triggers audio warnings, which intensify the closer a vehicle approaches. The visual warning interface, as well as the warning distance can be adjusted based on user preference.”

Garmin’s Varia RTL515 features a radar and provides visual and audible alerts for vehicles approaching from the rear, while the Varia RCT715 also features a built-in camera, but it doesn’t show you what’s going on behind as you ride.

Luna Oculus is said to use “computer vision to detect approaching vehicles”, the idea being to give you time to react if cars get too close.

Luna also says that the system maps “vehicle proximity events” – close passes – allowing you to see where these events occur most often and plan safer routes.

Until now, Luna Oculus has been developed as a business-to-business (B2B) design, but it’s now shifting towards direct-to-consumer sales with an Indiegogo crowdfunding campaign that starts on 5th June 2024.

How much? Luna says the standard retail cost will be €199 (about £169) for the camera and mounting accessories. There will be several different perk tiers on Indiegogo, with discounts in the region of 15–35%. Luna will also include some tiering additions, like extended free app subscriptions (€72 per year) and warranties. 

If you’re interested in knowing more, you can visit the Luna Oculus Indiegogo pre-launch page and sign up to be notified when the Indiegogo campaign launches.

PRO launches aero cockpit for gravel riding

This week, Shimano launched its 12-speed GRX Di2 groupset for gravel riding, while its sister brand, PRO Bikegear, introduced an aero cockpit designed for gravel. 

Shimano says that aerodynamic gains in gravel frames and wheels have become standard but "dedicated aerodynamic cockpits have been in short supply". So, the Discover Aero Carbon Handlebar aims to address the need to offer speed, comfort, efficiency and control in gravel riding. 

The handlebar features "aerodynamically optimised tops", similar aero handlebars you'd find on modern road bikes, 12 degrees of flare, and a 4-degree sweep forward which encourages riders into a more aero position according to the brand. 

The Discover Aero Handlebar is designed to be paired with the new Discover Stem 10 which comes with a +/- 10-degree angle, compared to the a +/- 6-degree angle on the existing PRO Discover stem. 

Mark Kikkert, PRO Bikegear’s Product Development Team Manager says, "integrated cockpits might be all the rage right now, but for the vast majority of riders the combination of a handlebar and stem simply allows for a better bike fit". 

The Discover Aero Handlebar, priced at £349.99, is available in three different widths of 40, 42 and 44cm. The Discover Stem 10 adds seven stem length options of 60, 70, 80, 90, 100, 110 and 120mm, and is priced at £99.99. Both products will be available from August.

Rapha and Factor Bikes announce a bike hire partnership 

Rapha and Factor Bikes have teamed up to provided Rapha Cycling Club (RCC) members with access to Factor's Ostro Vam, the bike used by the WorldTour team Israel-Premier Tech, as a hire option. 

RCC is an active cycling community made up of 'Chapters' based out of Rapha's Clubhouses around the world. Through their global bike hire services, members can hire a bike in cities where they don't have their own to explore on two wheels. 

The Ostro Vam is “the benchmark aerodynamic, lightweight race bike”, according to the brand, and this special edition combines Rapha's iconic pink and black accents with Factor's raw carbon fibre textures. Completing the bike is Black Inc's 48/58 "aero-optimised and lightweight" wheelset.

Hire bikes will be available soon in London, New York, Miami, San Francisco and Mallorca Rapha Clubhouses, within additional locations coming within the month. For members, hire is charged by the day and costs a pretty reasonable £35.

Will this sunscreen developed for cyclists improve your performance?

Solarsport has developed an SPF 30 sunscreen promising to "stop skin damage while improving performance". Who knew sunscreen could be the secret weapon we all needed to go faster? 

While that sounds like a huge stretch, Solarsport's claim starts to make a bit more sense in the '5 reasons why sunscreen is good for sport' page on its website.

Solarsport says that sunscreen is good for recovery, because your body doesn't have to recover from being burnt and won't divert as many white blood cells, and it means your body's cooling mechanisms are "enhanced". A sunscreen that claimed to be aero would have been more fun, but in lieu of that we'll give Solarsport credit where credit is due. 

The brands' SPF 30 is said to be an invisible, quick drying and non-greasy mist, protecting against 97% of UV rays. Solarsport attributes its performance enhancing quality to its sweat-proof formula, ensuring it won't run into your eyes during activities. Surely by that logic, no sunscreen at all is performance enhancing too? 

Anyway, it comes in a 50ml bottle which is handy for fitting into your back pocket, and is available to buy on Solarsport's website for £9.99.

Thought about adding an indicator to your helmet again recently? Here's another one

> Best bike lights 2024

Appearing on Dragon's Den in 2018, Steve Ransom presented a prototype indicator and brake light designed for helmets. Six years later, BrighterBikes has launched Firefly, a wireless indicating brake light system said to fit to all helmets, bikes and backpacks. 

Designed and manufactured in the UK, Firefly features hi-brite LEDs, is rechargable via USB, and offers a claimed battery life of 20 hours. The device is also waterproof. 

> Where cycling products go to die: bright bike tech that has failed to catch on

The system includes a finger touch control unit that can be mounted on your bike's handlebars which you can control to indicate, and the brake light activates automatically when you brake. 

So, will this finally be the cycling indicator that sees some success, or will it join the hundreds of others consigned to the cycling indicator scrapheap? We'll be following with interest...

Bonus comedy video: this engineer has no time for your e-bikes, your indexed shifting or your... front derailleurs?!

Why this came up on our recommended videos about a month after it was angrily uploaded we're not sure, but we think you need to hear YouTube fitness OG and engineer Scooby1961's take on the humble bicycle to make you appreciate your own bike a little bit more. 

In a mini-rant that would make the save the rim brake crowd blush, our self-confessed 'grumpy retired engineer' has his say on e-bikes (only for lazy people apparently) and indexed shifting, which for all its ease of use is too difficult to work on and likely to go wrong compared to good old friction shifting, so we're told. 

His next target? Front derailleurs, for similar reasons in that he thinks they're too much of a faff to maintain... so he's gone 1x, right? Not exactly, as our retired grumpy engineer says he just took the front derailleur off his triple chainring bike, stopping to physically move the chain to the next chainring when he needs to instead! We're going to go out on a limb and suggest that a faffy front mech shift is marginally more efficient, but each to their own. 

We jest of course, and the most important thing is that this internet legend is out on his bike in the fresh air. Even if he does have some unsavoury opinions, and returns home with oily hands after every ride...
