Frequently Asked Questions

Product

Do your bikes come assembled?

For bikes ordered online for delivery, these will arrive in a box with about 20% of the assembly required upon unpacking. We have detailed videos showing the steps for assembly on our Youtube channel. 

Checkout our Tutorials page to find the assembly video for your bike model.

For bikes purchased in person at our Burleigh Heads Showroom, we do offer an assembly service for a fee. Drop in or contact us for more information regarding this service.

What comes in the Bike box?

In all our Kids electric bikes you'll find almost everything you need to get started! Including...

  • Your Bike
  • Fenders (on applicable models)
  • Basic Tool Kit
  • Standard AU Charger
  • Instructional Manual with links to Instructional videos

Are E-Bikes legal to ride on the road?

In general, yes — e-bikes are legal to ride in Australia, provided they meet specific regulations. Most states follow a version of the European EN15194 standard, but there are important differences across states and territories.

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

  • Have a maximum power output of 250W (some exceptions apply — for example, NSW allows up to 500W for certain classifications)
  • 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
  • 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

Remember:

Every state and territory in Australia may interpret or enforce e-bike laws differently. E-bikes with motors larger than 250W, or those with throttle-only operation, may be restricted to off-road or private property use only and could be considered non-compliant for public road use.

👉 It is your sole responsibility to ensure that your e-bike is compliant with local laws and regulations in your area. Ampd Bros does not guarantee "road" compliance in any specific state or territory and is not liable for misuse or non-compliant use of any product.

We strongly recommend contacting your local road and transport authority to confirm the latest rules applicable to your intended use.

Examples of devices that are designed strictly for off road private property use only.

  • Surron Light Bee X, Hyper or Ultra bee Motorcyles
  • RFN Motorcycles
  • Lil Rippa Bikes & Similar Bikes with no pedals designed for off road use.

What is an E-Bike?

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.

How long is your warranty?

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! 

For all other products see our warranty page for more info.

Checkout the full terms and conditions here.

Where can I view your Bikes?

Our head office retail showroom is located at:

67 Dover Drive, Burleigh Heads 4220 QLD, AU

However we have a bunch of dealers across Australia who carry our range and can also provide after sales support.

Checkout our list of dealers here and be sure to give them a call to check stock availability, they may even be able to order a bike in for you to view otherwise. If not be sure to call us and we may be able to arrange for you!

Is there an Age Limit for E-Bike's?

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.a

Shipping

How does my bike come delivered?

All our E-Bikes come securely boxed and are shipped 80% assembled and do require some assembly. 

Should you need assistance you can checkout our Tutorials & Tips page for assembly videos or you can also refer to a store near you for bike builds and service.

How long will it take to receive my order?

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.
