        Yes sure you can unlock your bike to the maximum speed the motor is capable of producing. But take note of the regulations in your area as doing so may deem your bike legal for off road private property use only. Be sure to check the speed limit in your area but typically speaking exceeding 25km/h is not legal practice in most 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 EPAC Compliant Electric 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!

        Checkout the full terms and conditions here.

        Our bikes are water resistant 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!

        Ace Demon MKII does not disappoint!

        I know that Amp'd Bros claim that the dual 1000W motors in the Ace Demon MKII eats hills for breakfast, but I didn't expect just how easily it would pull my heavy frame up some of Hobart's steep hills! The suspension makes for such a smooth off road ride and the big comfy seat is great for a long cruise along the waterfront tracks. If you're on the fence about getting one, just do it.

        Demon X lives up to the hype

        The Demon X is fantastic so far, I’ve been riding for a few weeks and can’t fault it. Dual motors make a world of difference especially on soft dirt and the suspension makes pretty much anything a smooth ride. Taken some pretty decent trips on it and haven’t used more than half the battery yet. Had a small issue with the derailleur hanger from shipping and the support guys knew what it was and how to fix it pretty much instantly.

        The Ampd BROS Experience 😎👍!!!

        Stop looking elsewhere for your E- Bike . This is exactly where you should be .
        Here are the reasons why :-
        ● Australian company.

        ● Quality check and assurance done here in Australia before shipping and this is then repeated if purchased from approved dealers before customers handover .
        ● The freedom of purchase selection:-
        ● Outstanding customer service care and attention.
        With genuine interest in getting you on the right bike.
        Now with that I will add an excellent reception to my enquiries by David who was informative, friendly, enthusiastic.
        Everyone seriously stop the nightmare of navigating dodgy deals on the internet with highly questionable real world quality.

        Speak to real people and allow them to impart their wealth of knowledge and experience.
        You will be very glad you did.
