If you’re buying an e-bike for your child in Western Australia, the most important thing to know is this: WA takes compliance seriously — more seriously than anywhere else in Australia. A legal e-bike must be pedal-assist only, limited to 250 watts and 25 km/h, and meet the EN 15194 standard. Get that right and your child’s e-bike is treated just like any other bicycle. Get it wrong and the bike could be seized and destroyed.
Can My Child Ride an E-Bike?
There is no specific minimum age for riding a compliant e-bike in Western Australia. If the e-bike meets the legal definition of a bicycle (250W pedal-assist, 25 km/h cutoff, EN 15194), your child can ride it wherever bicycles are permitted.
That said, most manufacturers recommend their e-bikes for children aged 14 and above, and younger riders should always be supervised. A helmet is mandatory for every rider, regardless of age — no exceptions.
What Makes an E-Bike Legal?
Under the Road Traffic Act 1974 (WA), to be treated as a bicycle an e-bike must tick three boxes:
- Pedal-assist only — the motor helps while you pedal and stops when you stop
- 250 watts maximum continuous rated power
- 25 km/h cutoff — the motor stops assisting at this speed (you can still pedal faster under your own steam)
The bike should also comply with EN 15194, the European standard for electrically power-assisted cycles. Look for this on the spec sheet or compliance plate. If a bike doesn’t meet these requirements, it’s classified as a motor vehicle and needs registration, insurance, and a licence — none of which are available for a typical e-bike.
Throttle Rules
WA is strict on throttles. A compliant e-bike may have a walk-assist mode that works up to 6 km/h — that’s walking pace, designed to help you push the bike up a hill or through a car park. Any throttle that propels the bike faster than 6 km/h without pedalling makes the bike non-compliant.
This is the rule that catches most people out. Many imported e-bikes come with full-speed throttles. In WA, riding one of those on a public road or path is illegal.
Where Can You Ride?
A compliant e-bike can be ridden anywhere a regular bicycle is allowed:
- On the road (with traffic, in bike lanes)
- On shared-use paths and cycle paths
- On footpaths (children under 12, or adults accompanying a child under 12)
Standard bicycle road rules apply. Ride on the left, signal your turns, and give way to pedestrians on shared paths.
E-Bikes on Public Transport
Transperth allows bicycles on trains at all times — there are dedicated bike areas in each carriage. Compliant e-bikes are treated the same as regular bikes, so your child can ride to the station, take the train, and ride the last stretch to school or sport.
Buses and ferries have more limited capacity, so check Transperth’s current policy if you plan to combine modes.
Penalties
The WA Department of Transport and WA Police work together on e-bike enforcement, and WA was the first state in Australia to implement seize-and-crush enforcement for non-compliant e-bikes. In January 2026, WA Police crushed more than 50 seized e-bikes collected during Perth patrols. This isn’t a distant threat — it’s active, ongoing enforcement.
If your child is caught riding a non-compliant e-bike, the bike can be seized on the spot. Fines for riding an unregistered motor vehicle also apply. The simplest way to avoid all of this is to buy a bike that meets the 250W pedal-assist standard from a reputable retailer.
Buying Tips for Parents
- Check the spec sheet for “250W rated power,” “pedal-assist,” and “EN 15194.” If any of those are missing, ask the retailer to confirm in writing.
- Avoid bikes with full-speed throttles. Walk-assist to 6 km/h is fine; anything more is not.
- Buy from an Australian retailer who understands local laws. Our red flags guide covers the warning signs in detail. Cheap imports from overseas marketplaces often ship with non-compliant firmware or throttle modes.
- Keep the receipt and compliance documents. If the bike is ever questioned, you’ll want proof it meets the standard.
- Fit a quality helmet — it’s the law, and it’s the single best protection you can give your child. For help choosing the right bike, see our guide for first-time buyers.
Frequently Asked Questions
Does my child need a licence to ride an e-bike?
No. A compliant e-bike (250W pedal-assist, 25 km/h cutoff) is legally a bicycle in WA. No licence, registration, or insurance is required.
Can my child ride an e-bike to school?
Yes, as long as the e-bike is compliant and your child wears a helmet. Check with the school about any on-site rules for parking or storing e-bikes.
What happens if we buy a bike that turns out to be non-compliant?
It could be seized by WA Police and destroyed. You would also face fines for riding an unregistered motor vehicle. This is why buying from a reputable Australian retailer matters — they should only sell compliant bikes and be able to show you the EN 15194 certification.
Are e-scooters treated the same as e-bikes in WA?
No. E-scooters have separate rules and restrictions in WA. This guide covers e-bikes only.
Can my child ride on the footpath?
Children under 12 may ride on footpaths, and an adult supervising a child under 12 may also ride on the footpath. Riders aged 12 and over should use the road or designated cycle paths.
