NSW police crush 36 illegal ebikes after seizing high-powered models on northern beaches
NSW recorded 233 ebike-related injuries and four deaths in the first seven months of 2025, prompting the enforcement action.
Ebikes must behave like bicycles, not motorcycles.
Mark
So police crushed 36 bikes in one operation. That's a lot. How did they identify which ones were illegal so quickly?
Mimi
They used portable speed-testing machines—dyno units. You put the bike on the device, click the throttle, and it measures the power output and top speed in minutes. That's how they found the 14-year-old's bike could hit 90km/h.
Luke
But here's the thing: we don't know if all 36 bikes were tested the same way, or if some were seized based on appearance or rider behavior. The reporting says they were seized, but doesn't detail the testing protocol for each one.
Mimi
Fair point. What we do know is that the legal limit is 25km/h with power assistance, and anything faster is illegal. The 90km/h bike is undeniable.
Mark
Why would a 14-year-old have a bike like that? Is this a trend, or an isolated case?
Mimi
The police statement mentions "recent incidents of illegal, dangerous and reckless e-bike use" on the northern beaches, which suggests it's not just one kid. But we don't have specifics on what those incidents were.
Luke
Right. We have injury data—233 injuries and four deaths in the first seven months of 2025—but we don't know how many of those involved illegal, modified bikes versus legal ones ridden recklessly. The connection is implied, not proven.
Mark
So the enforcement is preventive, not reactive to a specific incident?
Mimi
Appears so. The new powers came in late August, and this operation happened in September. It's part of a coordinated push with the NSW government to get ahead of the problem.
Luke
But "ahead of the problem" assumes the problem is primarily illegal bikes, not rider behavior or infrastructure. That's a policy choice, not a fact.
Mark
What happens to the owners now?
Mimi
They have 14 days to tell police if the bike was stolen. After that, the bikes get crushed.
Mark
And if someone didn't know their bike was illegal?
Luke
That's the gap. We don't know if there's a grace period, education campaign, or amnesty. The warning from Transport NSW says "make sure it's road-legal, otherwise you risk losing the bike," but that's after the fact for these 36 owners.
Il Polso
- A teenager's ebike hitting 90km/h — nearly four times the legal limit — crystallised what authorities had been watching build for months: a modified-bike culture outpacing the rules meant to contain it.
- NSW recorded 233 ebike injuries and four deaths in just the first seven months of 2025, a toll that has already surpassed the full-year figure for 2024 and now rivals traditional road fatalities.
- Police deployed portable dynos on the northern beaches and swept 36 illegal machines in a single operation, the first major use of new powers allowing officers to seize and destroy non-compliant bikes.
- Owners have a 14-day window to claim their bike was stolen before it is crushed — a narrow appeal that quietly acknowledges some riders may not have known they were breaking the law, while others almost certainly did.
- Authorities are planning statewide operations in coming weeks, with a pointed message to parents: if your child's bike can exceed 25km/h under power, it is not a bicycle — and it will be removed.
On Sydney's northern beaches, a 14-year-old's ebike capable of 90km/h became the symbol of a broader reckoning — one in which the promise of clean, accessible transport has collided with the human cost of unchecked modification. NSW police, armed with new legislative powers and portable speed-testing devices, seized 36 non-compliant ebikes in a single day, signaling that the state has moved from warning to consequence. Behind the enforcement lies a quiet arithmetic of harm: more ebike injuries in seven months of 2025 than in all of 2024, and four deaths that no climate-friendly commute can offset.
On a Friday morning in Warriewood, an officer pressed the throttle on a 14-year-old's ebike and watched it surge past 40km/h in seconds. Later testing confirmed it could reach 90km/h — nearly four times the legal limit. That single machine became the centrepiece of a sweep across Sydney's northern beaches in which police seized 36 illegal ebikes, the first major enforcement action under new legislation granting officers the power to destroy non-compliant bikes.
The crackdown was enabled by portable dyno units — compact devices that measure speed and power output in minutes — deployed by Transport for NSW secretary Josh Murray. What might have been a routine patrol became a systematic operation. Assistant Commissioner David Driver announced further statewide sweeps in coming weeks, framing the action as a response to a pattern of dangerous riding. Seized bikes now sit in custody; owners have 14 days to claim their machine was stolen before it is crushed.
The numbers behind the enforcement are stark. NSW recorded 226 ebike injuries across all of 2024. In the first seven months of 2025 alone, that figure had already reached 233, with four deaths — a rate that has begun to rival traditional road fatalities for the same period.
Ebikes arrived in Australia as a genuine alternative: cleaner, cheaper, and healthier than cars. But the technology proved easy to subvert. Swapped batteries, reprogrammed controllers, and bypassed pedal-assist systems can quietly transform a legal bicycle into something closer to a small motorcycle. Murray's warning was direct: if a bike can exceed 25km/h under power, it is not legal to ride in public — and riders risk losing it permanently.
How many more illegal ebikes are circulating on Sydney streets remains unknown. The two-week appeal window hints that some owners may have been unaware of the limits. Others almost certainly were not. Either way, the machines will be destroyed, and the message is now unmistakable: NSW has the tools, the law, and the intent to remove them.
On Friday, NSW police pulled a 14-year-old off his ebike in Warriewood and tested it on a portable speed machine. When an officer clicked the throttle, the bike surged past 40km/h in seconds. Later testing showed it could hit 90km/h—nearly four times the legal limit. That single bike became the centerpiece of a larger operation: police seized 36 illegal ebikes across Sydney's northern beaches that day, the first major enforcement push under new legislation that gives officers the power to destroy non-compliant machines.
The crackdown reflects a sharp turn in how NSW is treating modified ebikes. In late August, police gained authority to seize and destroy any ebike exceeding the legal speed threshold of 25km/h, or any bike that doesn't cut power assistance at that speed. The government invested in portable dyno units—machines that measure power output and top speed in minutes—to identify offenders quickly. Transport for NSW secretary Josh Murray deployed one of these units on the northern beaches on Friday, turning what might have been a routine patrol into a systematic sweep.
The operation was framed as a response to what police called "recent incidents of illegal, dangerous and reckless e-bike use." Assistant Commissioner David Driver announced on Saturday that more operations would roll out across the state in coming weeks. The message was clear: most ebike riders follow the rules, but those who don't will face enforcement. "Police will enforce the new legislation if people ride non-compliant vehicles," Driver said. The seized bikes now sit in police custody. Owners have 14 days to contact police and claim their bike was stolen and being ridden by someone else on Friday. After that window closes, the bikes will be crushed.
The enforcement action sits against a backdrop of genuine injury data. NSW recorded 226 ebike-related injuries in 2024. In just the first seven months of 2025, that number had already climbed to 233 injuries, plus four deaths. For context, road fatalities involving vehicle drivers, passengers, and motorcyclists totaled 187 for the same period in 2024, rising to 194 in 2025. The ebike injury surge has outpaced traditional vehicle harm, at least in the early months of this year.
Ebikes arrived in Australia with considerable promise. They were marketed as climate-friendly alternatives to cars, a way to reduce transport emissions and urban congestion, even as a hedge against youth screen addiction. They offered exercise, cost savings, and a cleaner commute. But the technology proved easier to modify than regulators anticipated. Riders could swap batteries, reprogram controllers, or install throttles that bypassed the pedal-assist design. A legal ebike becomes a small motorcycle. A teenager on a modified bike becomes a hazard.
Murray's statement on Saturday carried a warning aimed at parents and riders: "Ebikes must behave like bicycles, not motorcycles. If your bike can operate like a motorcycle under throttle or go more than 25km/h while being powered, it is not legal to ride in public." He acknowledged that most people were using ebikes legally, but framed the problem as a small group creating outsized risk. "Before you or your child jumps on an ebike, please make sure it's road-legal, otherwise you risk losing the bike."
The 14-year-old's bike in Warriewood was not an outlier. Police found multiple non-compliant machines in a single operation on a single day. What remains unclear is how many more illegal ebikes are circulating on Sydney streets, or how many riders understand the legal limits. The two-week appeal window suggests some owners may not have known their bikes were illegal. Others almost certainly did. Either way, the machines will be destroyed, and the message will be reinforced: NSW police now have the tools and the mandate to remove them from the road.
