Lachlan Morton’s Traka 2025 bike sports exceptional puncture repair hacks

Lachlan Morton ranks as one of the best (and popular) multi-discipline endurance riders on the planet and he lined up for the start of the Traka 360 race having recently set a new record for riding around his native Australia. His Cannondale SuperX LAB71 was ready for a fast day out.

The SuperX has recently been revised to increase tyre clearance with the official figures now safely allowing for the 50mm tyres Morton rode at Unbound 2024.

His machine was built using an interesting mix of road and gravel components, but it also featured a very specific selection of puncture repair solutions, with each being ready for deployment quickly in the heat of battle.

2024’s Men’s Unbound 200 winner was unfortunate to suffer a serious mechanical mid-way through Saturday’s race, but given Morton’s dialled setup, we just had to take a closer look.

The drivetrain is a mix of road and gravel components, which Morton says is somewhat down to availability through the EF Education-EasyPost road race team. He told us he prefers the feel of Shimano’s road shifters, but that GRX is a better fit when it comes to derailleurs. Liam Cahill / Our Media
Despite opting for some jazzy mullet setups in the past, Morton went with 44mm rear / 42mm front Vittoria Mezcal tyres for the Traka 360. He said after only a few weeks on the new bike, he didn’t want to alter the geometry with a larger front tyre. His race ended after cracking his front rim, though neither he, nor his mechanic Tom Hopper, were sure on what caused the failure. Liam Cahill / Our Media
This pre-loaded tubeless plug is for larger holes. Morton said the positioning on the top tube makes it super easy to access when a tyre is rapidly losing air. Liam Cahill / Our Media
A tool for slower punctures (and smaller holes) was mounted under his Wahoo bike computer. Liam Cahill / Our Media
Less time-efficient puncture repair methods were located out of the way, with a tube and lever stashed at the bottom bracket. The way Morton sees it, if you’re putting in a tube, you’ll be stopped for longer than when using a plug. Liam Cahill / Our Media
Morton carries a CO2 canister in the pockets of his skinsuit. This mini pump rarely comes out, but it’s good to have a dependable back up.

A Canyon X DT Swiss collab fork, pro bodges and Paw Patrol – Traka 2025 tech gallery

The Traka is fast becoming one of the most important gravel races of the season with the 200, 360 and 560km races being hotly contested.

Forming part of the Gravel Earth Series, the Traka attracts a host of pro riders, but like so many gravel events, it’s open to all. The result is a melting pot of hacks, bodges and some of the latest gravel tech available.

Last year, the race was heavily disrupted by stormy conditions, largely clement weather greeted 2025’s participants. 

This year’s event gave us our first proper look at Canyon’s new gravel race bike, showed the divide in tyre choice and served up some questionable last minute mods.

It looks like DT Swiss has been called upon for a gravel collab – Canyon now seems to have a specific suspension fork for the Grail. Liam Cahill / Our Media
Canyon, despite being asked very nicely, was tight lipped when queried on it, but the travel looks to be in the region of 40mm. Liam Cahill / Our Media
There are other interesting design features, such as a rebound adjustment knob at the bottom of the non drive-side fork leg. Liam Cahill / Our Media
DT Swiss has also paid close attention to the aesthetics with this sleek fork crown area – could this new fork be trying to bridge the aesthetic gap between gnarlier off-road forks and road-going designs? Liam Cahill / Our Media
Danni Shrosbree was also aboard a new bike, though this Argon18 Dark Matter was launched on Monday. Liam Cahill / Our Media
The bike features some very cool tech with space for 57mm tyres front and back. There’s also a hidden mount for a front derailleur. Liam Cahill / Our Media
The key tech trend continues to be the adoption of MTB tyres and Continental’s Race King was a common sight on the start line. Liam Cahill / Our Media
Second in the women’s 200km race, Rosa Klöser, pushed her Canyon Grizl frame clearance to the limit. Liam Cahill / Our Media
Winner of the women’s 200km race, Sofia Gomez Villafane, opted for a Specialized S-Works Crux with curiously unmarked S-Works Tracer gravel tyres. Liam Cahill / Our Media
But look closely and a small ‘50mm’ marking is visible. Liam Cahill / Our Media
The Argentine’s setup was very simple – the only addition to the SRAM Red / Eagle AXS mullet drivetrain was this small chain guide. Liam Cahill / Our Media
Elsewhere, I was delighted to see riders getting inventive with some aero mods (that’s right, aerodynamics is truly a thing in gravel). This rubberised material stuck onto Klöser’s handlebar gives her a little extra grip, but also some forearm comfort when riding in an aero position. Liam Cahill / Our Media
There were plenty of road groupsets on display – Mattia Di Marchi’s Campagnolo Super Record WRL was the most beautiful (and the least likely). Liam Cahill / Our Media
His Basso Palta was resplendent under the Spanish sun, but it was these small sections of sandpaper which caught my eye, there to hold tightly onto bottles. Straight out of the Paris-Roubaix playbook. Liam Cahill / Our Media
But Harry Tanfield took things to another level, by pinching packing materials from his bike box. The idea? Exceptional. The execution? Questionable. Liam Cahill / Our Media
This über-neat storage of a tubeless tool and multitool was the antidote to Tanfield’s bodge. Liam Cahill / Our Media
Speaking of puncture repair, riders continued to squirrel away pre-loaded tubeless plug tools in random locations. This one looks slightly… risky. Liam Cahill / Our Media
When the award for ‘most left-field bike’ is handed out, there can be only one winner. SJ and Andre will tackle the 100km route aboard this tandem. Andre took me for a quick spin and I am only slightly worried for them! Liam Cahill / Our Media
At least they’ll be fuelled well. They told me they were aiming for al dente. Liam Cahill / Our Media
And their Paw Patrol-branded horn can sound the finish klaxon on this tech gallery. Toot! Liam Cahill / Our Media

Woman Racer Spotlight: Gretchen Zoeller

Name: Gretchen Zoeller 

Hometown: Nottingham, UK

How did you get into cycling? It’s a long story! I was 144 kg till 19. At 12 years old I discovered sport. I threw the discus and hammer, then got injured and lost 100kg. I started training in Brazilian jiu-jitsu at the age of 22 and have successfully competed all over the world.  I was the first British woman to medal at black belt in Brazil and the 3rd British woman to be awarded a black belt.

Then at 41 my life was turned upside down. I was diagnosed with a knee issue which turned out to be quite a serious disability. I decided to retire from the professional division and had my last fight. On the advice of my knee surgeon, I started cycling in mid 2020. I couldn’t do a 5-mile ride without stopping for hills even though I was fit. 

I met a lady at a local club who persuaded me to try an introduction to racing course she was teaching (thanks Liz!). I tried a few TTs in 2022 and enjoyed them. Racing filled the competitive gap I was missing after leaving high-level sport. 

In 2023 I signed up for a full season of able-bodied TT’s. I medalled at the VTTA national 100-mile TT & won two open 10s. I now compete for the Born2Bike racing team. My physio suggested I contact British Cycling for a para assessment which after a year of fighting was completed in June ’24. My knee is a degenerative disability and some days I can’t walk. Some Zwift races I compete using one leg!

How many years have you been racing on Zwift? 3 years 

Are you part of a Virtual team? Definitely! REVO, my team, is fantastic. You know when you’ve found “your people.” I love the ladies in my team, they are amazing. 

What do you love most about racing? Pushing myself. That feeling of destroying yourself during a race and the exhilaration at the finish. Oh, and the spare calories! 

What is your favourite style of race (e.g. points, scratch, iTT, TTT, Chase, duathlon)?  I do love a TT! 

What is your favourite Zwift women’s race series? TBD, but anywhere the whole team are involved and fighting for positions.

What is your most memorable racing experience, inside or outside or BOTH? I was in Cambridge at a 10-mile TT. I’d had bad news from my doctor. I thought f*** it. I emptied the tank and did 22.51. I cried at the side of the road after and 2 other riders stopped to check on me. They asked why I was crying. I said, “Because I just got an epic PB.” We rode the 8 miles back to HQ together! 

What is your favourite food to eat post race? Protein shakes and cold pizza made by the expert Maria at Pizza Paz (I fought middle-heavyweight).

What advice would you give to a woman entering her first Zwift race? Have high expectations for yourself because you are stronger than you realise, and you can achieve more than anyone ever expected of you. 

Any upcoming race you are looking forward to? I’m recovering from knee surgery and just want to start training ASAP. 

Where can people follow your racing adventures? I’m old skool. I don’t like to post much, but if you like photos of cute German Shepherds then @gretzoeller on Insta.

**A big shout out to my biggest supporter. My husband Ben. He gets my bikes ready, maintains and repairs both them and me (which is a much bigger job!). I literally couldn’t do it without him.

Bastion’s new fully custom Archetype is the best-looking road bike I’ve seen in 2025

Bastion’s creations are things of rare beauty, with hand-crafted carbon fibre tubes mated to sculpted titanium lugs. The Australian brand’s bikes are considered by many as masterpieces of bicycle engineering.

It has been a decade since Bastion released a new road bike and the new Archetype brings everything it has learned in the intervening years to the fore.

It’s the combination of mirror-polished 3D-printed titanium, raw filament-wound carbon and exquisite attention to detail that makes this custom aero race bike stand out.

Combine all that with a wind-tunnel proven design and, in my opinion, the Archetype is 2025’s best-looking bike.

Filament-wound carbon

Bastion Archetype
The combination of mirror-polished 3D-printed titanium and raw filament-wound carbon looks spectacular. Bastion

Each tube is constructed using filament-wound carbon fibre.

Continuous individual fibre strands are woven around a mandrel to construct high-strength lightweight hollow tubes.

True aero profiles

Bastion Archetype
All of the tubes are based on NACA profiles. Bastion

The Archetype’s tubes are different. For the first time, the tube profiles are based around NACA (National Advisory Committee for Aeronautics) true aerodynamic profiles.

That makes the new Archetype one of the first fully custom aero road bikes available. These tubes are then bonded to aero-optimised 3D-printed titanium lugs.

The new bike has tyre clearances of 34mm and uses a Universal Derailleur Hanger rear dropout for added practicality.

Wind-tunnel tested

The Archetype was proven in the Silverstone wind tunnel. Bastion

The complete bike was wind-tunnel tested at the Silverstone Sports Engineering Hub by Stephen Roche of the Bike Tailor.

The complete bike, with Shimano Dura-Ace Di2 and Partington’s R39/44 wheelset, was compared to Bastion’s Icon Superleggera. The Archetype reduced drag by 6-8 watts across 0-15° yaw angles at 35 km/h – speeds said to be typical for Bastion’s clientele.

For an ‘average’ rider outputting 200 watts, this represents a significant advantage. At higher speeds, the gains are even more dramatic. At 50 km/h, the Archetype slashed aerodynamic drag by an impressive 18-25 watts, according to Bastion.

10 years in the making

Bastion Archetype
Every element of the Bastion is hand-crafted, even the one-piece cockpit. Bastion

Ethan York, Bastion’s R&D manager, explained the design behind the Archetype: “Our mission was to increase aerodynamic performance without compromising stiffness or weight. The Archetype achieves this with refined tube profiles and an ultra-efficient joining structure.

“We approached the Archetype with the mindset of evolution, not just innovation. We’ve taken the lessons of the past decade – from filament winding to moulded carbon fibre techniques – and redefined their potential in a new aerodynamic context.”

Attention to detail

Bastion head badge
The head badge is made from a 0.05mm-thick slice of etched stainless steel. Bastion

The head badge hasn’t been spared the aero overhaul. Instead of Bastion’s usual 3D-printed badge, the Archetype’s is etched from a 0.05mm-thick slice of stainless steel. It’s placed under the finished frame’s clear-coat finish.

Pricing hasn’t been announced, but I’d expect it to be somewhat POA.

Even if, like me, you’ve no chance of being able to afford this most exclusive of superbikes, Bastion has made its online configurator open to all. Previously, you could only access it after placing a deposit.

This Colin McRae-inspired Canyon gravel bike is perfection

Alec Briggs will line up for the Traka gravel race aboard a very special Canyon Grail CFR. His bike has been heavily customised in the style of Colin McRae’s famous Subaru Impreza rally car. 

Briggs, founder of and racer for the Tekkerz CC team, arrived in Girona, Spain, ahead of the Traka with possibly the hottest gravel race bike of 2025. 

His Canyon Grail CFR features deep blue paint, bright yellow graphics and gold wheels that all hark back to Colin McRae’s career as a rally driver.

McRae was at the sharp end of World Rally driving in the 90s and his blue and yellow Subaru Impreza became an iconic design. Following McRae’s death in 2007, his race cars became highly sought after, with TopGear reporting his ‘555’ car sold for £230,000 in 2017.

In an Instagram post, Briggs touched on the time he spent playing Colin McRae’s video games, and said he wanted to channel the spirit of “if in doubt, go flat out”.

Briggs has opted for a roadie-influenced build, along with some of the coolest wheels we’ve ever seen. But watch out for the Tekkerz dinosaur.

Swytch’s new Max+ ebike conversion kit, with a 40-mile range from its removable battery, arrives for testing – here are Warren’s first impressions

Swytch, the maker of some of the world’s best-selling ebike conversion kits, has launched its most innovative kit to date.

After announcing the Max+ last year, alongside a complete Swytch bike, it’s now finally available to buy – and one has just arrived at BikeRadar for review.

The new Max+ has a large battery capacity, an integrated front light and a USB-C charge point, while Swytch is also emphasising the kit’s battery safety technology.

The ebike conversion kit market is moving at pace, with the Max+ arriving hot on the heels of Boost’s Brompton-specific system, Cytronex’s new thru-axle rear-motor option and Skarper’s click-on, click-off kit.

However, concerns remain about unregulated and low-quality systems.

Bringing it to the Max

Like previous generations, the Swytch Max+ can convert almost any bike into a pedal-assisted electric bike, with a 250-watt motor and a top assisted speed of 15mph.

The Max+ promises an increased range of up to 40 miles from its 274.5Wh-capacity battery.

There’s also a Max++ option, promising a boosted range of 60 miles.

The Max+ works by replacing a regular front wheel with a Swytch motor wheel (built at Swytch’s Norwich factory). The quick-release bar-mounted battery can be removed at the flick of a lever. If you remove the battery, your bike becomes a standard bike again.

Swytch’s CEO, Oliver Montague, says this circumvents Transport for London’s recent ban on non-folding ebikes, if a Swytch bike’s battery is removed.

The Max+ is now in stock and on sale at £999.

Swytch Max+ first impressions

I’ve received two versions of the new Max+ kits for testing.

The first is built with a 700c disc wheel, which has found its way onto the Genesis Day One used to test the Boost kit.

The second is built around a 20in wheel for a Kansi folding bike. I’ll be following up with full tests of both options soon.

Swytch Max  unboxed
The Max kit arrives in fully recyclable packaging, with a comprehensive instruction manual. Warren Rossiter / OurMedia

It’s a slick-looking system, with a substantial mount for the battery. There are cables to run to the front-hub motor and down to the pedal sensor, which makes your donor bike look somewhat different.

I’d like to see Swytch adopt a wireless pedal sensor, much like Skarper’s strap-on rechargeable unit.

However, I’m impressed by the Swytch kit’s simplicity, along with the presentation, packaging, instructions and overall design.

The fitting of both kits is simple and requires minimal tools: hex keys, snips or scissors for the cable ties, a 17mm spanner for the wheel nuts, and that’s it.

The comprehensive and well-illustrated fitting manual helps things along, and it’s good to see the kit ships in fully recyclable packaging, too.

The battery itself, with its built-in front light and side illumination, is very well thought-out. It’s IPX6 waterproof-rated, which means it’s tested by being sprayed with water at a rate of 100 litres per minute, at a pressure of at least 15psi, for at least three minutes from all directions. This should make it weatherproof for all riding conditions.

Swytch Max  remote

The inclusion of a USB-C charge port is most welcome, because it means the battery can double-up as a power pack, and its 272Wh capacity is enough to recharge an iPhone approximately 200 times.

Fitting-wise, it took 25 minutes to convert the Kansi folder and 35 minutes for the Genesis.

Stay tuned for full reviews of the two kits once testing is complete.

Canyon is now selling bikes on Amazon – but only a select few models

US consumers can now buy Canyon bikes via Amazon. The German direct-to-consumer bike brand has listed a selection of entry-level to mid-range urban, recreational and mountain bikes. 

Speaking to Bicycle Retailer and Industry News, a Canyon spokesperson said: “Expanding into this space is intended to meet a new consumer on an established platform, making cycling more accessible and convenient for everyone.” 

Just don’t expect to find Canyon’s top-flight Aeroad or Ultimate models on Amazon. The company says selling products through the online retailer is to complement its premium range that’s only found on Canyon.com. 

Targeting casual to intermediate riders, Canyon’s Amazon storefront has bikes ranging from just over $1,000 to $5,599. 

The range of bikes includes the Canyon Spectral 5, Spectral 125 CF 7 and Stoic 4. There is also a selection of electric bikes available, including the Grand Canyon:ON 7, Torque:ON 7 and Precede:ON Comfort 7.

If you’re looking for road bikes or gravel bikes, you’ll have to stick to Canyon’s website, for now at least. 

The move to Amazon follows a period of change for Canyon. Last year, the brand expanded its service partner network in the US through a partnership with REI, the nation’s largest outdoor retailer, adding 28 locations to buy its bikes. 

The direct-to-consumer brand’s network already includes 66 independent bike shops in the US.

Last month, Canyon also announced it had laid off an undisclosed number of employees in the US, in a move that was not tied to changes in tariffs. But it said it was employing a “shifting gears roadmap” to strengthen its direct-to-consumer model and grow new markets.

In the UK, Canyon recently opened two ‘Customer Experience Locations’ in London and Sheffield.

These bricks-and-mortar stores follow four Customer Experience Locations in Europe. Canyon is hoping to expand this number to 15 in 2025 across Europe and the US.

Over the years, Canyon has developed a reputation for value, with its direct-to-consumer model eliminating bike shops and enabling it to keep its margins high.

Expanding onto Amazon and focusing on physical locations to buy its bikes doesn’t mean Canyon has neglected its direct consumers, though. In February, Canyon launched the MyCanyon bike customisation programme, which offers consumers a range of paintjobs and componentry, including different stem lengths and groupsets.

Faster, lighter, cheaper – is Hunt’s new Aerodynamicist the ultimate performance clincher wheel?

Hunt has launched a new range of Aerodynamicist wheelsets that combine class-leading aero efficiency (backed up by wind-tunnel testing) with low weight, at a lower price than their industry-leading rivals. Could these be the performance wheels we’ve been waiting for?

The updated Aerodynamicist wheel line is being launched in three sizes: 34mm, and 44/46mm and 54/58mm-depth combinations.

The wheelsets have Enduro bearings as standard, as well as carbon and steel spoke options.

The new hooked rim design, which has been optimised for 28-30mm road tyres, comes with claimed weights from 1,175g and prices starting at £1,149.

All-new Aerodynamicist

Aerodynamicist rim profile
Hunt’s new Aerodynamicist rim profile uses a hooked design. Hunt

The new in-house engineered Aerodynamicist range differs from the Sussex wheel specialist’s high-end Limitless wheelsets. The new differential rim design is based around hooked rim profiles rather than hookless, a standard Hunt debuted back in 2016, alongside ENVE.

Going with a hooked design rather than hookless will be music to the ears of fans of clincher tyres. With brands still launching high-performance clincher tyres, the Aerodynamicist range could be the best option around.

Hunt’s aim with the new wheelsets was to match the previous-generation Aerodynamicist wheels across all sizes, but now optimised for larger tyres (from 28 to 30mm).

The Aerodynamicist has been developed over three years, with 47,000 hours of computer processing time alongside lots of wind-tunnel testing.

Different sizes

Hunt Aerodynamicist wheels.
Hunt’s 44/46 wheelset has differential rim sizes front and rear. Hunt

The new rim profiles come with a 22mm internal width across all heights, although, like the Limitless, the external widths vary across the sizes. The front and rear profiles also differ.

Hunt’s senior design engineer, Patrick Brown, told us this not only improves aerodynamic efficiency, but also helps reduce the mass in the rims, bringing down overall weight across all models.

Hunt Aerodynamicist 54 58
The Hunt Aerodynamicist’s largest size combines a 54mm-deep front wheel and a 58mm-deep rear wheel. Hunt

The largest of the trio comes with a 54mm-deep, 31.7mm-wide front rim and a 58mm-deep, 30mm-wide rear. The all-rounder option comes with a 44mm-deep front and 30mm width, and a 46mm-deep rear with the same 30mm external width.

The lightest option comes with 34.5mm-deep rims, both with a 28.4mm external width.

All wheels come with a 22mm internal rim width.

Options and weights

H Ratchet freehub

The new Aerodynamicist range is available with either UD Carbon spokes or triple-butted aero wing steel spokes.

All wheels come with Hunt’s hubs, constructed from lightweight 6066-T6 aluminium with a 7075-T6 alloy axle. The rear hub comes with the H Ratchet 40T DBL freehub system.

The dual-sided ratchet has a 40-tooth drive interface for a nine-degree engagement. Hunt says the ratchet requires less shell material compared to the standard pawl system, making for a lighter hub.

Proven faster

Hunt claims the new Aerodynamicist range, paired with a 28mm Schwalbe Pro One tyre, offers an average 1.4-watt (2%) saving compared to the previous models.

When benchmarked against industry-leading wheelsets, Hunt’s wind tunnel results were positive.

All the wheel sizes were tested in the wind tunnel using Mavic’s WAD (wind averaged drag) protocol to analyse the data. WAD is explained as “The time spent at any given yaw angle will be different, depending on the conditions and route”.

To give a consistent method of combining these yaw angles into a single (WAD) value, Mavic has developed and published a ‘ponderation law’.

Wind angles over 15 degrees are unusual (and the WAD takes this into account), but this is a situation where the steering moment experienced by the rider is accentuated, leading to a feeling of instability.

Above 15-degree yaw angles, although experienced less often, it can have a significant effect on aerodynamic performance if stalling has occurred, leading to airflow detachment.

Wind tunnel results

In the shallowest 34/34 size, the Aerodynamicists were only outperformed in low aero drag (WAD) by Shimano’s Dura-Ace C36s, which bettered the Hunt wheels by 0.58W, although the Aerodynamicists weigh 172g less than Shimano’s 1,368g. The Hunts bettered Reserve’s 34/37, the DT Swiss ERC 1400 35, Campagnolo’s Bora Ultra WTC 35, Roval’s Alpinist CLX II and Mavic’s Cosmic 32.

In the 44/46 size, the Hunts topped the testing, besting Mavic’s Cosmic 45 SL, the ENVE Foundation 45, Zipp’s 353 NSW, the DT Swiss ERC 1400 45, Zipp’s 303 Firecrest and 303s and Campagnolo’s Bora WTO 45s. The difference between the top and bottom of the list, however, was a mere 2.47W (WAD). The Aerodynamicists are the lightest in this test group.

On the largest 54/58 wheels, the Aerodynamicist also topped the testing table, besting ENVE’s SES 4.5, Zipp’s 404 Firecrest, the Reserve 52/63, Shimano C50, Zipp 454 NSW and Roval’s Rapide CL II (round spoke version). The difference between the top and bottom of the range tested was 3.12W (WAD), and again, Hunt’s 54/48 was the lightest wheelset at this depth.

For a full run-down of the aerodynamic testing, head over to Hunt’s website to read the white paper that covers both results and testing protocols.

Trump’s tariffs will be ‘devastating’ for US bike industry, according to open letter to President

The US bicycle industry’s trade association, PeopleForBikes, says Trump’s tariffs will have “devastating impacts” on the industry if they aren’t adjusted in the short term, in an open letter addressed to the President. 

PeopleForBikes represents more than 340 US manufacturers, suppliers and distributors of cycling products. Published this week, the open letter requests tariff relief or an exclusion process for bicycles and bicycle equipment.

“The current tariffs on complete bicycles and components used for assembly, imported from countries around the globe, will have devastating impacts on our industry if not adjusted in the near term. We are hearing concerns around additional layoffs and the risk of more companies closing their operations, including some of our few remaining domestic manufacturers,” the letter reads. 

The tariffs announced by Donald Trump in early April have already begun to cause chaos in the cycling industry. Specialized and Trek have hiked prices in the US, while other brands have cancelled shipments, and Silca even described launching a product in the US as “not viable”. 

Silca Electtrico pumps
Silca says it’s not viable to sell its Elettrico Ultimate electric pump in the US. Silca

While Trump has said his tariffs will boost US industry, PeopleForBikes warns that difficulties persist in moving the supply chain. 

“[E]ach bicycle may have 200 or more component parts that are still primarily sourced from sub-suppliers in foreign countries,” PeopleForBikes explains. “Developing a domestic manufacturing base for this wide variety of components will take substantial time and capital investment at a time when capital is hard to come by and cash flow is tight. Even without new, additional tariffs, our industry was already projecting a 3.7% decrease in sales, driven by higher aggregate price levels and weaker consumer confidence.”

The trade association says that while the USA once made all the bicycles it needed domestically, this has not been the case for several decades. The letter says that since the mid-1990s, low-cost imports from China have threatened American companies, and that a combination of “unfair foreign competition and unwise U.S. trade policy” led to the closure of bicycle factories in the country. 

According to a 2021 study, 87 per cent of bikes imported to the US are from China.

PeopleForBikes says it appreciates President Trump’s “focus on China’s competitive threat” and closing of the de minimis loophole, which eliminates the duty-free import of low-value commodities “which has undermined the U.S. bicycle industry and local bike retailers across America for many years”. 

The letter also outlines how US manufacturers are facing increased steel and aluminium prices from foreign and domestic sources, while the lack of domestic textile manufacturing could put cycling clothing manufacturers out of business. 

Current and proposed tariffs on bicycle helmets is another issue the letter, sent on 29 April, raises. It says these tariffs “make buying this essential and legally required safety equipment much less affordable” and could leave cyclists without protection. 

“The bicycle industry has enriched American lives for more than a century,” says PeopleForBikes president and CEO Jenn Dice. “We urge the administration to give our businesses the runway they need to compete globally, invest domestically, and keep biking safe, affordable, and accessible for everyone.”

You are 44% more likely to be fatally injured if hit by an SUV, according to this new study

The likelihood of a cyclist or pedestrian being fatally injured is 44% higher if they are hit by an SUV or light truck compared to smaller passenger cars, according to new research from the London School of Hygiene & Tropical Medicine, published today.

Researchers used real-world collision data from more than 680,000 collisions over the last 35 years as part of a new analysis of existing studies.

The odds of fatal injury increased by 44% for people of all ages struck by an SUV (Sport Utility Vehicle), compared to those hit by a regular passenger car, while the odds for children increased by 82%, and 130% among children under the age of 10.

More SUVs

The authors of the study estimate that the proportion of car crashes involving an SUV is around 45% in the USA and around 20% in Europe, with SUVs said to be making up 48% of new car sales globally in 2023, up from 15% in 2010.

They say that if all SUVs were replaced with regular passenger cars, the number of pedestrians and cyclists killed in car crashes would decrease by an estimated 17% in the USA and by 8% in Europe.

Anna Goodman, assistant professor at the London School of Hygiene & Tropical Medicine, and senior author of the study, says there has been a huge increase in the sale of ever-larger cars worldwide with the “findings indicating that this proliferation of larger vehicles threatens to undermine all the road safety gains being made on other fronts”.

The study suggests fatalities among children under the age of 10 increased by 130%. Getty Images

A previous study highlighted a key reason for the increased risk is likely to be the taller and blunter profile of the front end of SUVs, with a taller front end meaning a pedestrian or cyclist is struck higher up on their body (e.g. the pelvis not the knees for an adult, or the head not the pelvis for a child). It also means the pedestrian or cyclist is more likely to be thrown forward onto the road, at which point the striking vehicle may hit them a second time or roll over their body.

Oliver Lord, UK Head of the Clean Cities Campaign, responded to the London School of Hygiene & Tropical Medicine research with this statement: “It’s alarming to see fresh evidence confirming SUVs are linked to more fatal crashes. No-one buying a car would want to put children at greater risk.

“We urgently need government to take action on carspreading. Councils could introduce fairer parking charges that reflect the size and weight of these vehicles, while government reviews taxes to address the real harm caused by supersized SUVs. That would provide more opportunity to invest in priorities like fixing potholes and better public transport.”

Elsa Robinson, who worked on the study as an MSc Public Health student, says: “analysing over half a million crashes from countries from across the world tells us that SUVs and other similarly large vehicles are much more likely than traditional passenger cars to cause serious harm if they strike a pedestrian or cyclist.

“Our findings also highlight that these larger vehicles are particularly dangerous for children, especially young children. This could be because children are shorter in height, and are therefore more vulnerable to the risks of being hit by vehicles with a tall front end.”

This update boosts the DJI Avinox ebike motor to 1,000 watts amid EU legislation row

DJI has released an update to its Avinox motor, increasing the Turbo mode’s power from 850W to 1,000W.

Previously, the Avinox’s 1,000W maximum output was only available in a 30-second Boost mode designed to assist on the steepest gradients, but will now be constantly on tap in Turbo mode.

The move comes as legislation on powerful ebike motors is discussed in Germany, with a maximum output of 750W being suggested.

DJI says it is “closely monitoring the EU regulations and is committed to adhering to established guidelines”.

Whether the Chinese brand’s update is coincidental or pays no heed to the proposed changes is unclear. Either way, it’s likely to prove controversial with european manufactures such as Bosch, who have backed the campaign to limit motor power output.

Free firmware update

DJI’s Avinox motor already came with some mind-bending stats. Forbidden

The power increase comes as part of DJI’s 1.1.0 app version, released on 26 April, which the brand says is a “grey version intended for the collection of feedback”.

“App version 1.1.1 released on the same day addressed compatibility issues,” DJI explained. “We’re preparing to release a new firmware update in May, with specific details to be shared upon the official release. We appreciate your attention and patience as we work to provide you an improved experience.

“We’re closely monitoring the EU regulations and are committed to adhere to established guidelines. We are also committed to providing our users with support in light of any regulatory changes that may impact our products.

“Should such circumstances arise, we will ensure that our users have access to the necessary resources and guidance for adapting their purchased products.”

Alongside the 150W boost to Turbo mode, the update brings more control over charging, enabling you to choose a charging rate, with faster speeds resulting in speedier top-ups and slower prolonging battery life.

You can also change the length of Boost mode, enabling you to set it above the previous limit of 30 seconds.

The UX of the topbar-mounted screen has also been updated, with data now being shown in bar and line charts.

A stopwatch function has also been added, which should enable you to time your runs or see how long you’ve been waiting for your mates at the top of the hill.

What does this mean for EU regulation?

While it seems DJI has doubled down on its high-power ebike motor, many European manufacturers have welcomed legislation to limit motor output.

The feeling is that many manufacturers see electric bikes as having a Goldilocks position in the market, with no registration or licensing required to own or operate an EAPC-regulated bike.

The fear for some brands is that increasing maximum power will give legislators more reason to push for registration and licensing, which will likely impact sales.

This could be perceived as the European brands protecting the market from Chinese disrupters such as DJI and Bafang.

Norco issues voluntary recall on new Sight VLT CX eMTB

Norco has announced a voluntary recall on all of its model year 2025 Sight VLT CX electric mountain bikes. 

This is due to concerns with the rearmost rear brake insert coming loose, which Norco says is a safety concern while riding. 

As a result, Norco recommends to stop riding the electric mountain bike: “Out of an abundance of caution, we’re asking all riders of these bikes to stop riding immediately while we investigate and gather more data.” 

All of the models in the range are affected, which are as follows: 

  • Norco Sight VLT CX C1 150
  • Norco Sight VLT CX C2 150
  • Norco Sight VLT CX C3 150

The Sight VLT CX was launched earlier this month. It is claimed to offer a 20 per cent weight reduction over the previous model, despite boasting more battery capacity and equal power.

The bike uses Bosch’s latest Gen5 Performance Line CX motor and retains its predecessor’s 160/150mm suspension travel, while rolling on a mullet setup.

If you have questions, Norco says: “Your Norco retailer is your best point of contact, and they’ll be kept informed throughout this process.” 

“We know this is an inconvenience, and we appreciate your patience and understanding. This request comes from our commitment to performance, safety, and the trust you place in every ride,” Norco says in the stop ride notice. 

Norco says you can also reach its team directly at warranty@norco.com or 1-800-663-8916 if you’re in the USA or Canada. 

You can read the full stop ride notice here, which was issued last Friday.

What are those?! Winspace teases new T1600 aero road bike with bonkers D-shaped vents on seat tube

Winspace is launching a new T1600 aero road bike with bonkers D-shaped vents where the seatstays meet the seat tube.

As it stands, the T1600 has only been launched in China, with a global launch planned later next month. 

Winspace is one of the best-known Chinese bike brands. Founded in 2008, it offers performance road bikes at more budget-friendly prices. 

The brand’s previous T550 aero road bike was first launched in 2017 and was updated five years later, and it cut a far more conventional shape compared to the T1600. 

The T1600’s vents are said to reduce air turbulence and improve the aerodynamic performance of the bike. That’s according to Winspace, anyway.

Is this the latest in aero tech? Weight Weenies / Winspace

In principle, the vents seem similar to how Trek introduced a hole to the Madone’s seat tube, called IsoFlow. 

Trek says IsoFlow improves aerodynamics by accelerating the airflow through the turbulent wake of the bike and rider. 

But we don’t currently know enough about Winspace’s new design to say exactly if that’s what’s going on here. 

Winspace says the frame weighs 900g in an unpainted size medium and that it combines T100 and T1100 carbon fibre with Kevlar reinforcement around the head tube. 

Winspace T1600 seatstays
Apparently the T1600 is 5.5 watts faster than the T1550 Gen 2, but Winspace is yet to release any official details. cyclisthub / Winspace

According to cyclisthub, the T1600 was tested against a T1550 Gen 2 with a Winspace Zero SL handlebar in a wind tunnel, where it was 5.5 watts faster at 48km/h.

A Weight Weenies post suggests the frame has clearance for 32mm tyres and a T47 bottom bracket, but these details are unconfirmed.

Winspace has also launched a new ‘Kevlar’ handlebar and ‘Hyper’ wheels alongside the frame. 

With a handlebar, the T1600 is priced at 19,300 Chinese Yuan. That’s roughly £1,980 (or $2,648) but Winspace’s prices do not include duty or VAT. 

We have contacted Winspace for further details.
