For most of the e-bike’s mainstream rise, one fear has shadowed the conversation: that putting motors on bicycles makes them more dangerous. A new peer-reviewed study published in Findings in April 2026 says the opposite. When you adjust for how far people actually ride, e-bikes have a lower injury risk than conventional bicycles. The headline finding flips one of the most stubborn assumptions in the cycling-safety debate — and it’s exactly the kind of evidence policymakers and insurers have been waiting for.
What the Study Found
The new paper, by researchers Aslak Fyhri, Torkel Bjørnskau, and Henrik Siverts at Norway’s Institute of Transport Economics, paired two strong datasets: emergency-ward injury records from Oslo for 2023, and distance-based exposure estimates from the Norwegian National Travel Behaviour Survey. That combination is what makes this study unusually credible — it’s not just counting crashes, it’s counting crashes per kilometre actually ridden.
The headline numbers:
- Of 1,585 cyclist injuries requiring medical treatment in Oslo over the year, conventional bicycles produced more than twice as many injuries as e-bikes.
- The pooled travel-survey sample showed 1,696 cycling trips — 618 by e-bike and 1,078 by conventional bicycle.
- When the data was adjusted for distance ridden, e-bike injury risk per km was lower than conventional bike injury risk per km.
In plain English: e-bikes show up in the injury data, but they show up less than expected, given how popular they’ve become. That’s the opposite of what most public commentary has claimed.
Why This Result Is Counterintuitive — But Plausible
If you’ve spent any time in the comment section of an e-bike news article, you’ll have read claims that pedal-assist motors make bikes “too fast for the rider” and that e-bike crashes are routinely worse than conventional bike crashes. The Findings data doesn’t support that framing. Several plausible explanations emerge:
- E-bike riders are, on average, older. Older riders ride more cautiously, take fewer risks at intersections, and typically don’t sprint through cobbles or potholes the way younger sport cyclists do.
- E-bikes flatten the cost of riding longer routes. A rider who would otherwise be fatigued (and therefore less attentive) finishes a long commute fresher on an e-bike. Less fatigue = fewer crashes per km.
- Better infrastructure adoption. Norway’s protected bike-lane network has expanded fastest in the urban areas where e-bikes are most popular. The infrastructure itself reduces injury risk.
- Mass and stability. A heavier bike with more tire under it is harder to overturn at low urban speeds — exactly the moments when most everyday cycling crashes actually happen.
None of this means e-bikes are crash-proof. Severity of injury at higher speeds remains a legitimate concern, especially for Class 3 (28 mph) e-bikes. But on the most fundamental question — whether the average e-bike rider is more likely to get hurt per kilometer than the average conventional cyclist — the answer is now demonstrably “no.”
Why This Matters for Policy
Several U.S. states and European cities have either passed or proposed legislation that treats e-bikes as inherently more dangerous than conventional bikes — restricting them to faster classes, mandating registration, or limiting their use on multi-use paths. The Norwegian study is among the strongest pieces of evidence yet that those policies are not justified by injury data.
That doesn’t mean regulation goes away. As we’ve covered, the bike industry has formed a coalition to tackle e-bike regulation in a unified way, and there are legitimate questions to settle around battery safety, e-moto definitions, and modified throttle bikes. But the new evidence should reshape how regulators frame the conversation: not “e-bikes are dangerous and need to be controlled” but “e-bikes are part of the solution to urban-mobility safety, and the policy goal is to make them work even better.”
What This Means For You
If You’re Thinking About Buying an E-Bike
The injury-risk argument against e-bikes shouldn’t really weigh on your decision anymore — at least not for the typical commuter and recreational use case. Per kilometre, you’re statistically safer, not more at risk. That said, three habits will lower your odds further: wearing a helmet, riding with lights and reflective gear, and keeping the bike well-maintained. If you’re new to motors, our explainer on how e-bike motors work (mid-drive vs hub) is a good first read, and the broader e-bike vs traditional bike comparison covers cost, fitness, and practicality side-by-side.
If You Already Ride an E-Bike
Use the data to push for safer infrastructure in your area. Dedicated bike lanes are the single most effective intervention — they cut injury risk for both e-bikes and conventional bikes by large margins. The Norwegian study didn’t happen in a vacuum: it described a country with one of the best protected-lane networks in Europe.
If You Cycle the Old-Fashioned Way
The data is also a reminder that you, the conventional cyclist, are not particularly safe relative to e-bike riders — especially in mixed-traffic urban settings. If you’ve been holding off on buying lights, signals, or a better-fitting helmet, the per-km injury rate on your own ride is the real wake-up call. Our coverage of PIKIO’s record-setting Virginia Tech helmet rating is a good place to start if it’s time for a new lid.
Key Takeaways
- Study: “Relative Injury Risk of E-bikes and Conventional Bicycles,” published April 2026 in Findings by Fyhri, Bjørnskau, and Siverts.
- Data: 1,585 medically treated cyclist injuries in Oslo, 2023, paired with the Norwegian National Travel Behaviour Survey.
- Headline Finding: Conventional bikes account for more than twice as many injuries despite far less than twice the distance ridden — i.e., e-bikes have lower per-km injury risk.
- Why It Matters: Strongest peer-reviewed evidence yet that e-bike-specific safety regulations may not be justified by injury data.
The takeaway isn’t that e-bikes are danger-free — no form of road cycling is. But it is that one of the most popular criticisms of e-bikes appears, in the data, to be the opposite of true. As cities continue to redesign for cycling, the new evidence should give policymakers more reason to embrace e-bikes, not fewer.
