6 things to consider when buying a bike helmet

Tom's Guide27-05-2025
If you're planning to start cycling more, you need one of the best bike helmets, it's as simple as that. The extra protection you get from a helmet can make all the difference in a crash, and some helmets can now even help to prevent collisions.
To get the inside track on everything you need to know about bike helmets, we spoke to Juan Garcia Mansilla, co-founder of UNIT 1, a company that makes smart bike helmets and other cycling accessories.
Here's what you need to consider when buying your bike helmet.
Price is an obvious place to start, because you might well have a budget available to spend on your bike helmet.
'Prices vary a lot,' says Mansilla. 'You'll find basic helmets starting around $30. More advanced options — those with better materials, more features, or higher safety certifications — can go up to $300 or more.
'In our case, smart helmets with integrated lighting, MIPS [Multi-directional Impact Protection System], crash alerts and other features usually fall in the $150–$230 range.'
Bike helmets have to hit certain safety standards depending on where you live, and this is the first thing you should check with any helmet you're considering, especially if you're looking at cheaper helmets.

'In the U.S., the standard is CPSC,' says Mansilla. 'In Europe, it's EN-1078. Both were developed for traditional cycling speeds up to around 15.5 mph/25 km/h.
'For higher-impact protection, there's NTA-8776, a newer and more demanding certification created in the Netherlands, specifically with e-bikes and faster urban riding in mind.
'It tests for impacts up to 28 mph/ 45 km/h. No matter how fast you actually ride, a helmet that's NTA-certified offers a higher safety margin, full stop.
'For additional assurance, some riders also look to independent testing like the Virginia Tech Helmet Ratings, which assess real-world impact scenarios.'
Once you've found a helmet that fits your budget and the required safety standard, you need to make sure it's comfortable and fits well — if the helmet is loose, it will reduce how effective it is during impacts.
If you ride in hot countries, it's also worth making sure that the helmet has good airflow so it doesn't get uncomfortably sweaty during longer rides.
Helmets will work for all kinds of cycling, but there are different features you should prioritize depending on whether you're likely to be riding on the road or trails.
'Road cyclists typically look for something lightweight with maximum ventilation,' says Mansilla. 'Mountain bikers need more head coverage and durability. Urban helmets tend to be cleaner in design, with moderate airflow and visibility-focused features.
Technically, any helmet can work across contexts, but one that's built for your type of riding will always perform better.'
Bike helmets are getting smarter all the time, and if you have a bigger budget, you can get features that enhance your safety and ride experience.
'Our [UNIT 1's] helmets, for example, include integrated front and rear lights, turn signals, brake lights, a magnetic buckle for ease of use and crash alerts that send your location to an emergency contact if you fall,' says Mansilla.
'These tools are designed to help you avoid collisions and get help faster if one happens.'
This is something to consider after you've bought your helmet — when should you think about buying another one?
'After any crash, the helmet should be replaced, even if it looks fine,' says Mansilla. 'Impact can compromise the inner structure in ways you can't see.
'Without a crash, most helmets need to be replaced every three to four years, depending on use. UV exposure, rain, sweat and general wear all break down the materials over time.'

Is MRVL Stock a Buy, Sell or Hold at a P/E Multiple of 7.15X?

Marvell Technology MRVL is currently trading at a discounted valuation, with its forward 12-month price-to-earnings (P/E) ratio at 7.15X, which is lower than the Zacks Electronics - Semiconductors industry average of 8.63X. Given MRVL's discounted valuation, investors might be wondering: Is this an opportunity to buy, or are there deeper challenges that could keep the stock in check? MRVL Forward 12 Months (P/E) Valuation Chart Image Source: Zacks Investment Research Product Innovation Positions MRVL for Sustainable Growth What makes Marvell Technology's low P/E value more attractive is its robust business prospects. Due to the proliferation of AI and high performance computing among data centers and hyperscalers, MRVL is experiencing massive traction in custom Application Specific Integrated Circuits, Custom high bandwidth memory Compute Architecture, Co-Packaged Optics Platform and Multi-Die Packaging Platform products. As data centers perform a growing number of AI-related tasks, improvements in networking, interconnect, processing and storage capabilities, requiring high-performance semiconductor solutions become crucial. Marvell Technology is capitalizing on this opportunity with 800G PAM, 400ZR DCI, and 1.6T PAM digital signal processing products. This growth is evident in Marvell Technology's data center segment, which has taken the lead among all its segments with 76% year-over-year revenue growth in the first quarter of fiscal 2026. Marvell Technology also plans to expand its customer base among hyperscaler customers that seek to stand out, cut expenses and want to gain more control over their AI infrastructure. Marvell Technology has collaborated with NVIDIA and leveraged the latter's NVLink Fusion platform to build comprehensive rack-scale AI solutions to meet the needs of hyperscalers. Furthermore, the shift from copper to optical connectivity in AI infrastructure represents a massive growth opportunity for Marvell Technology's Co-Packaged Optics technology. Marvell Technology is also experiencing a recovery among its enterprise networking and carrier infrastructure segments on the back of the demand rebound. However, Marvell Technology is also facing some challenges. With all these factors at play, the Zacks Consensus Estimate for Marvell Technology's 2026 revenues is pegged at $8.2 billion, indicating year-over-year growth of 42.6%. The consensus mark for earnings is pegged at $2.79 per share, suggesting a whopping 77.7% year-over-year increase. Image Source: Zacks Investment Research Key Challenges Faced by Marvell Technology Marvell is experiencing traction in its AI-focused custom silicon semiconductor business, but the margin in this business is half the story, as the margin in this business is fundamentally lower, affecting MRVL's gross margin. MRVL's custom AI silicon, including XPUs, is lowering MRVL's gross margins due to higher costs associated with manufacturing these chips. The ongoing macroeconomic uncertainties, like the U.S. government's evolving stance toward China, from which MRVL gained about 43% of its fiscal 2025 total revenues, are also a concern for the company. Investors' skepticism has also been intensified by the fear of sanctions and persistent tariff threats to China, where Marvell Technology owns research and development facilities. Furthermore, softness in MRVL's consumer end market due to volatility in gaming demand and lumpy order patterns in the industrial business has added to investor concerns. Marvell Technology also faces intense competition from Broadcom AVGO and Advanced Micro Devices AMD in the AI accelerator space and Micron Technology MU in the HBM space. Advanced Micro Devices is a strong player in the custom silicon solutions and AI accelerator space with its semi-custom SoC offerings and Instinct Accelerators that power numerous data centers. Advanced Micro Devices' reconfigurable Alveo Adaptable Accelerator Cards are used to speed up compute-intensive applications in data centers. Broadcom's advanced 3.5D XDSiP packaging platform is specifically designed to enhance the performance and efficiency of custom AI XPUs for AI accelerators. Micron Technology is also riding a powerful wave of demand for high-bandwidth memory (HBM) and DRAM products, especially as AI workloads surge. Micron Technology has made significant strides in AI-optimized memory solutions, with its HBM3E products gaining attention for their superior power efficiency and bandwidth. These factors have weighed on MRVL stock's performance. Stock Price Performance of MRVL Marvell Technology has underperformed the Zacks Electronics - Semiconductors industry in the year-to-date period by losing 32.6%. Marvell Technology YTD Performance Chart Image Source: Zacks Investment Research Conclusion: Hold MRVL Stock for Now Marvell Technology is facing several headwinds, including geopolitical tension, shrunken margins and growing competition across its end markets. However, the company has strong long-term fundamentals supported by its strong foothold in the data center and high-speed networking market.

A Single CDN Isn't A Silver Bullet—It's A Point Of Failure

A Single CDN Isn't A Silver Bullet—It's A Point Of Failure

Mehdi Daoudi is the CEO and cofounder of Catchpoint, the Internet Resilience company. In tech, we love to talk about resilience. We architect for 'five nines,' build across multiple clouds and tout global high availability. But then we quietly route all our critical traffic through one content delivery network (CDN) and call it a day. If your entire digital delivery strategy hinges on a single CDN, you're not building for resilience. You're building for convenience and hoping nothing goes wrong. The Illusion Of Safety CDNs are fantastic! They've enabled us to have fast experiences since the late 1990s. They reduce latency, absorb spikes in traffic and cache content closer to users. But somewhere along the way, we stopped thinking of them as performance accelerators and started treating them like infallible gatekeepers. That's a dangerous shift. Even the best CDNs go down. Outages at major providers have taken down streaming platforms, e-commerce giants and financial services in seconds. Domain name system (DNS) propagation delays, border gateway protocol (BGP) leaks, transport layer security (TLS) misconfigurations—any of these can cascade into hours of downtime. And if you're locked into a single CDN, you have nowhere to go when that happens. The Contradiction Of Multi-Cloud With Only One CDN Enterprises spend millions to go multi-cloud. They distribute compute, storage and databases across AWS, Azure and GCP, often in complex configurations that require deep architectural alignment. But when it comes to the CDN layer—the literal entry point to your app—they often rely on a single vendor. You wouldn't run your back-end on just one availability zone. Why do it at the edge? It's the digital equivalent of putting a state-of-the-art alarm system on your house, then leaving the front door wide open. CDN outages don't just create latency. They can stall transactions, frustrate users and erode brand credibility and trust with your users and buyers. In industries like e-commerce, fintech and media, those impacts have a direct line to the bottom line. Understanding The Single-CDN Risks Organizations that rely on a single CDN often have no fallback when disaster strikes. Looking at the Cloudflare and Google Cloud outage in June 2025, Cloudflare services such as Workers KV, Access, WARP and Workers AI experienced significant disruptions. The impact extended to numerous high-profile platforms, including Spotify, Discord and OpenAI, all of which rely on Google Cloud, Cloudflare or both. This incident highlights the risks of single-CDN architectures. But here's the kicker: many companies not only rely heavily on a single CDN for critical traffic delivery—they also depend on that same provider for performance reporting. It's a bit like having your accountant serve as your bookkeeper, payroll manager and auditor all in one. While convenient, this kind of consolidation can make it harder to maintain independent oversight. Is that really a position of strength? When visibility and accountability are delegated to the very system you rely on, you're not measuring performance—you're just accepting a version of reality that may not serve your users or your business. While users experienced disruptions during the June 2025 outage, Google Cloud's official status page continued to show 'all green' for nearly an hour. For teams depending solely on provider telemetry, this translates to lost time, missed service level agreements (SLAs) and zero actionable insight. The Case For Multi-CDN: Not Just About Outages Going multi-CDN isn't just insurance against failure. It's also about performance, cost and control. • Regional Optimization: Different CDNs perform better in different parts of the world. Consider using the best in each region. • Vendor Leverage: Competition drives cost savings. If one CDN is underperforming or overcharging, you can shift traffic away. • Feature Flexibility: Some CDNs excel at edge compute, others at video delivery or TLS offload. Why limit yourself to one toolbox? A properly implemented multi-CDN architecture gives companies control when it matters most—during change events, rollouts or disasters. While setting up a multi-CDN strategy requires effort, it's not rocket science—and the tools exist. What's missing is the mindset. Too many teams still default to one CDN because it's 'easy' or 'standard.' But in today's hyper-distributed digital economy, that becomes a liability. Think of it this way—you wouldn't put your production database in a single region or run your back-end on a single VM. So why put your user experience in the hands of a single CDN? Building Resilience With A Multi-CDN Strategy To reduce risk, improve performance and take back control, reflect on these key considerations: • Redundancy By Design: Route traffic across multiple CDNs to avoid a single point of failure. Maintain availability even during provider outages. • Intelligent Load Balancing: Use smart routing and failover logic to respond in real time to availability, latency or geographic shifts in demand. • Routine Failover Testing: Simulate outages on a regular basis to ensure both your systems and teams respond effectively when it matters. • Independent Performance Benchmarking: Rely on third-party testing to measure CDN performance. Don't just take your vendor's word for it. • Localized Visibility: Understand performance at a micro-regional level, not just globally. What works in Frankfurt may fall short in Mumbai. • Strategic Optimization, Not Guesswork: Know which CDN is best for edge compute, static delivery or TLS offload and allocate traffic accordingly. Resilience doesn't happen by accident. It's not just about the cloud or the back-end—it's about every part of the stack, including the edge. If your entire architecture depends on one CDN—and you're trusting that same provider to tell you everything's fine—you're not building for resilience. You're hoping for luck. One last piece of advice: If your organization chooses to stick with a single CDN, don't double down on that risk by moving your DNS to the same vendor. When both your content delivery and your traffic control live under the same roof, any failure becomes total, and your ability to recover disappears. Redundancy isn't optional. It's how resilience begins. Forbes Technology Council is an invitation-only community for world-class CIOs, CTOs and technology executives. Do I qualify?

Sharpening Up Cybersecurity For A Mobile Workforce

Al Kingsley MBE is CEO of NetSupport, Chair of a multi-academy trust in the U.K, tech writer, speaker & author of multiple education books. Today's dynamic networks pose an ongoing challenge: keeping up with the constant flow of technology changes. Remote employees, self-service tools and mobile-first operations are reshaping cybersecurity risks—and how organizations must respond. Workplace technology is no longer confined to the boundaries of office buildings. That shift brings new responsibilities for keeping IT infrastructure secure. Whatever the structure of your network, security is the watchword. The scope and sophistication of external threats require continuous adaptation. A proactive cybersecurity strategy is no longer a luxury—it's essential. For mobile workforces, companies should focus on four key areas: • Managing lost and/or stolen devices: Mobile devices are small and portable, which makes them easy to lose or steal. Without proper safeguards, they can expose sensitive company data. Mobile Device Management (MDM) tools allow IT teams to lock or wipe devices remotely, reducing the risk of data exposure. • Providing secure remote support: Businesses need secure ways to support mobile devices. A secure-by-design remote support solution enables IT teams to troubleshoot issues while maintaining network integrity. • Controlling user access: Role-Based Access Controls (RBAC) limit user permissions and reduce the risk of unauthorized access if a device falls into the wrong hands. • Preparing for data breaches: Strong data management is a must, but so is readiness. Employees need clear protocols for responding quickly to a breach so IT teams can limit access and mitigate damage. As with all IT systems, testing is key. Look for vulnerabilities in your network, web applications, mobile platforms and cloud environments through the eyes of cybercriminals—and check that your remote access mechanisms are secure. Layered Security For Greater Protection A single security layer isn't enough. Companies need a multi-layered approach, especially with expanding device fleets and dispersed teams. Zero-trust architecture is one powerful layer. This approach verifies every user, device and application each time they access company resources—eliminating assumptions and guarding against both external and internal threats. Businesses can strengthen mobile security by implementing the following additional layers of protection: • Implement multifactor authentication (MFA): Verify user identity with multiple credentials before granting access. • Use endpoint detection and response (EDR): Monitor devices in real time to detect and respond to suspicious behavior. • Encrypt data at rest and in transit: Protect sensitive information through full-disk and end-to-end encryption. • Maintain robust backup and recovery systems: Ensure continuity during cyberattacks, outages or system failures. Securing Mobile Workforces Efficient mobile work depends on both technical safeguards and informed users. Social engineering threats are rising, so employees must be trained to detect and report suspicious activity. Businesses can improve mobile security by taking these specific actions: • Provide secure network access: Use virtual private networks (VPNs) or secure access service edge (SASE) models to encrypt and protect connections. • Enforce mobile device management (MDM): Monitor applications, apply security policies and remotely disable lost or compromised devices. The AI Effect AI is reshaping the cybersecurity landscape on both sides of the equation. In 2024, 77% of hackers reported using AI, with 86% saying it has "fundamentally changed their approach." But IT teams also have new tools. Machine learning and automation can scan data logs, analyze behavior patterns and flag anomalies in real time—accelerating threat detection and response. The catch? Many organizations aren't yet equipped to use AI effectively for defense. Until that changes, the skills gap gives attackers an edge. Training As A Frontline Defense Employees remain central to cybersecurity. They must understand their responsibility in protecting the organization—and be empowered to act accordingly. Training must go beyond one-size-fits-all. IT leaders should take a marketing mindset to training: segment audiences, target messages and deliver content in ways that resonate. One key insight: the assumption that older employees resist tech training is false. In fact, younger digital natives are more likely to ignore cybersecurity rules—bringing a more relaxed personal-tech mindset to the workplace. Older employees, research shows, are often more compliant with policy. Futureproofing Remote Work Remote, mobile and hybrid work models are now a fixture of modern business. SMEs must evolve alongside them to stay secure and remain competitive. Getting the tech stack right matters—but embedding cybersecurity awareness into workforce culture is what truly futureproofs the mobile enterprise. A secure, productive mobile workforce depends on both: tools that work, and people who know how to use them safely.
