Yes! e-bikes are legal in Australia. The only limitation is where they can be ridden. Bikes that meet national e-bike standards can be used on public roads and bike paths, while non-compliant devices may be restricted to private property.

To be considered legal for on-road use, electric bikes must:

• Be pedal-assisted only — the motor can only activate when the rider is pedalling (pedelec)
• Throttle-only operation is not permitted on public roads only private property unless it does not exceed 6km/h
• Have a maximum continuous output of 250W (some exceptions apply — for example, NSW allows up to 500W for certain classifications)
• Be not capable of an assisted top speed of more than 25km/h — after this, the motor must cut out
• Comply with all general road rules, including helmet use, speed limits and designated bike paths

Most negative media coverage relates to non-compliant or modified devices that exceed these limits or operate more like electric motorcycles.

Devices without pedals, with high-powered motors, or with unrestricted throttles are typically restricted to private property or off-road use unless they are registrable motorcycles.

👉 Laws and enforcement can vary between states and territories, so riders should always check their local road authority for the latest regulations.

Examples of devices that are designed strictly for off road private property use only (unless otherwise road registrable):

• Surron Light Bee X & Hyper Bee
• Surron Ultra bee / Storm Bee (Excluding ADR Road Registrable Models)

An E-Bike (Electric Bicycle) is a pedal-assisted bicycle that uses an electric motor to help you while riding — you still pedal, but the motor provides extra power for hills and longer rides. It’s designed to function like a traditional bicycle and typically complies with bicycle laws, motor and speed outputs depending on your local regulations.

In contrast, an E-Motorcycle is powered entirely by a motor with "throttle only" and does not require pedalling. Because of this, it’s legally classified as a motor vehicle and generally requires registration, licensing and road approval — just like a petrol motorcycle.

Some high-powered electric bikes look similar to motorcycles, which causes confusion. However, if a model exceeds local speed or power limits or operates purely by throttle, it is not considered a bicycle and may be restricted to off-road or private property use only.

Ampd Bros considers these high-powered units off-road use only products, and they should not be operated by children under 16 without parental supervision. Always wear a helmet and ride safely.

Summary: 

• An E-Bike is a pedal-assisted bicycle designed to follow bicycle laws — you must pedal to activate the motor with a max output typically of 25km/h and 250W.
• An E-Motorcycle is fully motor-powered, requires no pedalling and is legally classed as a motor vehicle, needing registration and licensing. Plus with a power output of far greater than 25km/h or 250W.

Age requirements for riding an E-Bike can vary between states and local laws, so it’s important to check the regulations in your area before riding.

While some regions may allow younger riders on lower-powered models, Ampd Bros strongly recommends that any rider under the age of 16 be supervised by an adult at all times.

E-Bikes are designed for responsible use and should be operated responsibly — always wear a helmet, ride safely, and follow your local road or off-road rules.

In off road only circumstances yes sure! We do have them available as optional accessories here, but keep in mind throttles are only legal on Private Property only hence why we do not include them with any of our bikes. Installing one would deem your bike illegal to use on any public road or property.

All our Ampd Brothers Adult range of electric bikes come backed by our 2 Year Nation wide warranty or 1 Year on Kids bikes! So you can ride worry free always!

Standard shipping normally takes 3-5 days. Express shipping is available on all small domestic orders (for an additional charge). 

Bulky freight such as E-Bikes will typically take substantially longer to deliver as more manual handling is required so with this in mind on average to most major cities is approx a 5-10day's. For more rural areas, NT, WA or TAS you could expect to see 14 days or more for your order to arrive.

International shipping times depend on the products and destination.

All international orders are shipped from Australia. Customers purchasing from outside of Australia are responsible for all applicable import duties, taxes, customs fees, GST, or local charges imposed by their destination country. These costs are not included in our product prices or shipping fees shown at checkout. You must also consider that items requiring chargers are supplied with "Australian" 240v wall plugs.

Ampd Bros does not cover or reimburse any of these charges. It is the customer’s responsibility to understand and comply with local import regulations before placing an order. Failure to pay these charges may result in delays, returned shipments, or forfeited orders — for which Ampd Bros cannot be held liable.
