Yes sure you can unlock your bikes motor to maximum output of 1,000W or to the bikes maximum speed. But take note doing so will deem your bike not legal for use on public property and exceeding 25km/h is not legal practice in all states.
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.
In virtually all states you do not need a licence or require any registration to ride an E-Bike, although if you are found to be riding under the influence of alcohol or exceeding the 25km/h speed limit for example, you may be penalised against your drivers licence.
All Australian states follow the same basis of rules which are established off the European standard EN15194.
In essence all e-bikes must;
- Not exceed 250W (Some states eg. NSW is 500W)
- Be propelled purely by pedal assist only and the pedals have to be used to keep the motor operating (a pedalec)
- Must not be operated purely by Throttle
- Must not be capable of exceeding 25km/h
- Abide by local law such as, wearing helmets, riding within speed limits in set areas etc
So the short story is that e-bikes are legal to use in Australia yes!
Be sure to check with your local authority as to any other regulations in your area.
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 YouTube for assembly videos or you can also refer to a store near you for bike builds and service.
Generally bike delivery will take longer than most small size articles as they are bulky and require more manual handling so on average to most major cities is approx a 5-10day delivery time. For more rural areas and NT, WA or TAS you should expect to see 14 days or more for your order to arrive.
We have a bunch of dealers across Australia who carry our range and 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!
All our Ampd Brothers range of electric bikes come backed by our 2 Year Nation wide warranty! So you can ride worry free always!

Our bikes are resistant to approx IP65 and are extremely weather resitant to rain etc. however as best practice we always advise to avoid water as much possible as even though they are extremely capable, water can create a lot more maintenance than necessary sooner rather than later!
Unfortunately we only offer selected tyres pre-installed as standard on our bikes. However we do have a huge range of tyres available as additional parts for all our bikes including street, mud or even white wall tyres!
