E-bike throttles explained: what's legal in each state

A throttle is a twist grip, lever or button that makes the motor drive the bike without you pedalling. A pedal-assist bike only adds power while the cranks turn. Australian e-bike law is built around pedal assist, so the question for any throttle is how fast it can take the bike on its own.

The 6 km/h rule

Every state allows a throttle that stops at 6 km/h. The NSW Government sums up the national position: a legal e-bike's motor cuts out at 25 km/h or when you stop pedalling, and any throttle or walk-assist feature must cut out at 6 km/h.^[1] Victoria calls it walk mode^[3]; Queensland says the throttle may help you start moving, up to 6 km/h.^[4] That is walking pace: enough to wheel a loaded cargo bike up a ramp or get rolling at the lights, not to ride on.

Most bikes sold here don't have more. Of the 22 bikes we list, 15 have no throttle at all, 6 have a walk or start-off throttle limited to 6 km/h, and 1 has a throttle its maker's manual lists to 25 km/h, which no state allows on a 250 W bike: our NCM Paris vs Paris+ comparison shows what that one difference does.

Above 6 km/h: the 200 W question

The argument is about the older power-assisted pedal cycle, a class with a motor of no more than 200 W that most states still list beside the 250 W pedal-assist bike. Because that class was defined by power rather than by pedalling, some riders read it as allowing a throttle. The states now answer differently:

• South Australia and the ACT: no. SA says the rider must use the pedals to set or keep the bike moving^[5], and the ACT says pedalling is required at any speed.^[6]
• NSW: two government sources disagree. The Road Rules still include the national 200 W class^[2], while the Government's FAQ says any e-bike that can be ridden on a throttle without pedalling is illegal and may only be ridden on private property.^[1]
• Western Australia, Tasmania and the Northern Territory allow a 200 W bike but don't say how far a throttle may take it.^[7][8][9]
• Victoria measures its 200 W class by peak output, so a motor that peaks higher doesn't fit it^[3], and Queensland has no 200 W class at all.^[4]

Where a state's page is silent, or two of its sources conflict, our rule checker answers "check" rather than "legal", and names the page.

What a throttle can cost you

A bike that runs on its throttle at speed doesn't fit any e-bike class, so it is treated as a motor vehicle: unregistered, uninsured and ridden without the right licence. In NSW that is how police decide today, by looking at whether a bike uses a throttle at higher speeds and how fast it can go.^[1] In Victoria, riding a non-complying e-bike on a road, bike path or shared path brings fines of over $1,000.^[3]

Switches, apps and off-road modes

Some bikes ship with a 6 km/h throttle that a button sequence, an app or a code can unlock. Victoria says a toggle switch or other tampering that overrides the legal limits makes the bike illegal^[3], and Queensland calls high-powered but locked bikes illegal devices that police can seize and destroy.^[4] What matters is what the bike can do, not how it is set when you ride past a police officer.

Buying a bike with a throttle

• Ask the seller for the throttle's top speed in writing. Above 6 km/h, the bike isn't legal on public roads in most of Australia.
• Prefer a throttle described as walk assist or start assist.
• Check there is no unlock mode, in the bike or its app.

Then put the bike's numbers into the rule checker for its verdict in all eight states, or browse the bikes we've checked, each with its throttle as the seller describes it.
