Can I unlock my bike's performance?
Can I unlock my bike's performance?
Yes sure you can unlock your bike to the maximum speed or watt output 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.
Checkout our Tutorials page on how to do so in your bikes display controls.
Can I add a throttle to my bike?
Can I add a throttle to my bike?
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.
Are E-Bikes legal to ride on the road?
Are E-Bikes legal to ride on the road?
Almost all Australian states follow a similar 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! Also with this in mind means you do not require any special licensing to ride!
However be sure to check with your local authority as to any other regulations in your area.

How does my bike come delivered?
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 YouTube 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?
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.
