Daniel (not his real name) shared that after purchasing two e-bikes from a Sydney store for himself and his wife, he decided to modify them to bypass the built-in speed limits.

By watching online tutorials and acquiring the necessary tool, he managed to adjust the bikes so they could exceed the legal 25km/h restriction, which is enforced across Australia.
Daniel mentioned to The Feed that the modified e-bike motors now can reach speeds of up to 45km/h, though during their morning commutes to work, they usually maintain speeds between 30 and 35km/h.
“The 25km/h speed limit feels too slow to us, particularly when sharing the road with cars,” he expressed.

He emphasized that the speed differential between e-bikes and traffic can create hazardous situations when riders are forced to join the flow of vehicles.

E-bikes currently have a speed limit of 25km/h in Australia.

While he said he has safety concerns about riding his hacked e-bike, he doesn’t see the risks as distinct from riding a normal bike — and overall, the couple enjoy the health, convenience and environmental benefits of riding e-bikes.

Lately, modified e-bikes have attracted attention in Australia. Even though laws across all states and territories mandate that e-bike motors stop running past 25km/h, hacking them is relatively straightforward — as demonstrated by Daniel’s e-bikes.

There are plenty of online instructional videos showing riders how they can hack bikes to increase speed limits, with some e-bike speed limits raised to up to 90km/h.
A number of companies in Australia — including some e-bike manufacturers — will also provide instructions, accessories or services to hack e-bikes’ speed limits on the condition that riders sign a waiver to only ride them on private property.
According to market research group Mordor Intelligence, sales and imports of e-bikes have tripled in Australia since 2020.

E-bikes that allow speeds over 25km/h or have motor power exceeding legal limits can be used on private property in all regions. However, on public roads, these are classified as unregistered motorbikes.

‘Severe trauma’

As the number of e-bikes in Australia has risen dramatically in recent years, the number of injuries and deaths caused by e-bike accidents has risen as well.

St Vincent’s Hospital in Sydney reported a noticeable increase in trauma cases linked to e-bikes in their emergency department in recent years.

In 2023, the St Vincent’s emergency room treated 45 trauma cases related to e-bikes, whether modified or not. So far this year, there have been 135 cases.

Dr. Tom Crofts, an emergency specialist at the hospital, informed The Feed that e-bike-related trauma cases typically involve “blunt force trauma” injuries resulting from rapid deceleration.

“We see quite severe trauma almost on a weekly basis now associated with e-bikes,” he said.
“Often cases that require surgical intervention and ICU admission and that is becoming more frequent as time goes by.”

Crofts said it’s “obvious” when patients have been hurt while riding modified e-bikes.

“Some of the injuries that we do see, you can safely assume that they’re going faster … above what they are capped at, which is the 25 kilometre an hour speed limit.”
There have also been deaths associated with modified or illegal e-bikes in recent years in Australia.

In May this year, 69-year-old Victorian pedestrian William Lothian was killed after being hit by a man riding a modified e-bike.

Analysis from international statistics has revealed that e-bikes are associated with more fatalities than standard, unpowered bikes, which has proved to be an emerging issue in some countries with a rapidly growing number of e-bikes.

A Melbourne University researcher investigated fatality statistics of e-bike riders compared to regular cyclists in China and Denmark, finding that e-bike users have a notably higher mortality risk.

Gaps in the law

These incidents have raised community concerns around modified and illegal e-bikes, prompting politicians to try to address gaps in Australia’s e-bike legislation.
Biking advocacy groups such as the Bicycle Network say amendments to the Road Vehicles Standards Act in 2021 that removed e-bikes from the legislation mean e-bikes don’t fall under the definition of a road vehicle.
This means that e-bikes don’t have to meet key safety standards when imported and easily hackable e-bikes are easy to bring into the country.

For example, even though the legal power of an e-bike motor on roads in NSW is 500 watts or in Queensland and Victoria 250 watts, e-bikes with motors of up to 6,000 watts can be imported into Australia.

Earlier this month, independent federal MP Sophie Scamps introduced a private member’s bill known as the Safer E-Bikes bill, seeking to address the legislative gaps.
Scamps’ electorate of Mackellar on Sydney’s northern beaches has been a particular target of police enforcement of e-bike laws, with police conducting a month-long crackdown on modified e-bikes there earlier this year.
There are significant penalties associated with e-bikes that run too fast — people caught riding illegally modified e-bikes in NSW can attract fines starting at $723.

Introducing the bill, Scamps — who previously worked as an emergency room doctor — said technology has outpaced safety and import regulations.

She called for e-bikes to once again come under the Road Vehicles Standards Act.
“While states and territories are responsible for setting speed limits and writing regulations on our roads and footpaths, the federal government also has a clear role to play in regulating and supporting safe e-bikes,” she said.

Many biking advocacy groups support legislation that restricts the e-bikes that can enter Australia, however some argue that speed limits should be increased to 32km/h, in line with US standards.

Allison McCormack, chief executive of the Bicycle Network, which supports keeping the 25km/h speed limit, told The Feed Australia needs standards for the e-bikes being imported.

“What we’re seeing is illegal e-bikes travelling up to 60,90km/h,” she said.

“This is why legislation is so important. We need to stop the ability to simply buy something that is an illegal motorbike and bring it into Australia and then subsequently they’re being used on the roads.”

Limit ‘too slow’

Daniel said he doesn’t mind the idea of more regulation on the e-bikes being imported — but he still feels the current speed limits set are unreasonable for everyday e-bike riders.

“I have seen a lot of crazy big e-bikes that look like motorbikes,” he said.

“I don’t have any issue with a crackdown on those bikes. I do however feel strongly that the 25km/h speed limit is too slow.”
