Cooly Bikes Warranty

- Frame
- Motor
- Battery
- Controller
- Display
- Charger and electrical components
What’s not covered
Warranty does not cover:
- Normal wear and tear (tyres, tubes, brake pads, grips, cosmetic marks)
- Damage from misuse, accidents, water damage, neglect or improper storage
- Unauthorised modifications or repairs
- Use outside intended conditions or failure to follow care instructions
How to make a claim
To lodge a warranty claim, contact our team with:

We’ll assess it quickly and guide you through the next steps.
Australian Consumer Law
Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage.
1 Year Comprehensive Warranty
At Cooly Bikes, we stand behind the bikes we sell.
Every eligible Cooly Bike is backed by our 1 Year Comprehensive Warranty, covering the specified components below against applicable manufacturing faults and defects during the warranty period.
If something doesn’t seem right, our team is here to help work through the issue and get you pointed towards the right solution.
Our voluntary warranty sits alongside your rights and remedies under Australian Consumer Law.
Our goods come with guarantees that cannot be excluded under the Australian Consumer Law.
You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage.
You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.
The benefits provided by the Cooly Bikes 1 Year Comprehensive Warranty are additional to any other rights and remedies available to you under Australian Consumer Law.
What's Covered for 1 Year?
The following components are covered under the Cooly Bikes voluntary warranty for 1 year:
Straightforward Support From Day One
Our 1 Year Comprehensive Warranty is a voluntary warranty provided by Cooly Bikes. It is in addition to your rights and remedies under Australian Consumer Law, and those rights are not limited to the one-year voluntary warranty period. Consumer guarantees apply automatically and cannot be excluded, restricted or replaced by this warranty.
The 1 Year Comprehensive Warranty begins from the date the original customer takes delivery of the product.
The one-year period applies to the voluntary Cooly Bikes warranty. It does not limit any consumer guarantee or other statutory right that may continue to apply beyond that period.
Transfer of Ownership
The Cooly Bikes 1 Year Comprehensive Warranty is transferable with the bike for the remaining balance of the original one-year warranty period.
A subsequent owner may access the remaining voluntary warranty period provided they can supply satisfactory proof that the bike was originally purchased through Cooly Bikes or an authorised Cooly Bikes distributor/dealer.
Transfer of ownership does not restart, reset or extend the warranty period. The one-year warranty continues to run from the date the original customer took delivery of the product.
For example, if ownership transfers six months after the original customer takes delivery, the subsequent owner may access the remaining six months of the voluntary warranty, subject to the warranty terms and satisfactory proof of the original qualifying purchase.
This transferability provision relates specifically to the Cooly Bikes voluntary warranty. Australian Consumer Law rights and remedies remain separate and unaffected.
What the Cooly Bikes Warranty Covers
During the warranty period, the Cooly Bikes voluntary warranty covers applicable manufacturing faults, defects or failures affecting the covered components where the issue arises during normal intended use of the product.
If a claim is covered by the voluntary warranty, Cooly Bikes will arrange an appropriate remedy depending on the nature of the fault and the circumstances.
This may include:
- Repair
- Replacement of an affected component
- Authorised service support
- Another appropriate remedy available under the voluntary warranty
Your remedies under Australian Consumer Law may differ depending on the circumstances and remain unaffected by this voluntary warranty.
Need to Make a Claim?
We've kept the process straightforward.
To start a warranty enquiry or claim, email:
warranty@coolybikes.comThere is no separate online warranty claim form.
Our team will review the information provided.
Depending on the issue, we may need to carry out troubleshooting, request additional information, arrange an inspection, request photos or video, or arrange assessment by an authorised service provider.
If the issue is covered by the Cooly Bikes voluntary warranty, we'll arrange an appropriate remedy based on the circumstances.
This may include repair, replacement of an affected component, authorised service support or another appropriate remedy available under the voluntary warranty.
Nothing in this process limits any remedy available to you under Australian Consumer Law.
- Your name and contact details
- Order details or other proof of purchase
- Bike model
- Serial number, where relevant
- A clear description of the issue
- Photos
- Video, where relevant
- Other reasonable diagnostic information relevant to the claimed fault
The Cooly Bikes Bike Registration form is separate from the warranty claim process. Registration does not activate or commence the warranty.
What Counts as Proof of Purchase?
We may ask for proof of purchase so we can identify the transaction and assess the claim.
A paper receipt is not necessarily the only acceptable form of proof. Relevant proof may include an order confirmation, transaction record, card or bank statement, receipt or reference number, or other documentation that reasonably establishes the original qualifying purchase.
Things to Know
When the Voluntary Warranty May Not Apply
The Cooly Bikes voluntary warranty does not generally cover damage or failure caused or contributed to by:
- Accident, collision, impact, abuse or misuse
- Stunts, freestyle riding or other use outside the product's intended operation
- Fire, flood, storm or other external events
- Water or environmental exposure where the issue was not caused by a covered manufacturing defect
- Rust, corrosion or environmental deterioration arising through use, storage or exposure rather than a covered defect
- Foreign objects, debris or external contamination
- Normal wear and tear
- Poor, inappropriate or neglected maintenance where that maintenance issue caused or contributed to the fault
- Incompatible parts or components where they caused or contributed to the fault
- Unauthorised modification, derestriction or tampering where it caused or contributed to the fault
- Unauthorised repairs or associated work where they caused or contributed to the fault
- Operation outside the model's approved configuration where that operation caused or contributed to the fault
- Transport damage arising from transport independently arranged by the customer where that damage was not caused by Cooly Bikes or its authorised freight provider
These exclusions apply to the Cooly Bikes voluntary warranty only. They do not exclude, restrict or remove any rights or remedies that cannot lawfully be excluded under Australian Consumer Law.
Normal Wear & Consumable Parts
Bikes contain components that naturally wear through normal use.
Normal wear and tear is not generally a manufacturing defect and is therefore not normally covered by the Cooly Bikes voluntary warranty.
Examples may include:
- Tyres
- Tubes
- Brake pads
- Bearings
- Seats and other contact surfaces
- Other consumable components
This does not mean a wear or consumable component can never be covered. If a component has a genuine manufacturing fault or defect, rights under this warranty or Australian Consumer Law may still apply depending on the circumstances.
Looking After Your Cooly
Regular maintenance helps keep your bike safe, reliable and riding the way it should.
We recommend servicing your bike appropriately for how often and where you ride it.
Damage caused or contributed to by neglected or inappropriate maintenance may fall outside the Cooly Bikes voluntary warranty.
Simply missing a service does not remove rights that may otherwise exist under Australian Consumer Law.
View our service menu and book here →Modifications & Approved Configuration
Cooly Bikes sells genuinely separate product configurations designed for different intended uses.
Unauthorised modification, derestriction, tampering, incompatible components, unauthorised repairs or operation outside the model's approved configuration may affect the Cooly Bikes voluntary warranty where they caused or contributed to the fault being claimed.
A modification, component or repair does not automatically cancel the entire voluntary warranty merely because it exists.
Australian Consumer Law rights remain unaffected.
Freight, Transport & Assessment
There is no fee to submit a voluntary warranty claim.
Because e-bikes are large and heavy products, please contact Cooly Bikes before arranging return freight or transport for a warranty claim.
Where a product or component can reasonably be posted or easily returned, Cooly Bikes may ask the customer to initially pay the applicable reasonable postage, freight or transport cost for assessment.
Where assessment by a qualified Cooly Bikes mechanic confirms a manufacturing fault covered by the voluntary warranty, Cooly Bikes will reimburse the reasonable approved postage, freight or transport cost.
Where a faulty product is large, heavy or difficult to return, including a complete eBike where applicable, Cooly Bikes will arrange or cover appropriate collection or transport where required by Australian Consumer Law.
Reimbursement
Approved reimbursement will be processed within 10 days of approval.
Please keep receipts or other reasonable evidence of approved postage, freight or transport expenses associated with a claim.
There is no blanket policy stating that assessment, inspection, collection, freight or transport charges automatically apply simply because a claimed fault is ultimately found not to be covered.
Where a bike or component needs to be transported, please package it securely and follow any reasonable transport instructions provided by Cooly Bikes.
Nothing in this section limits your rights or remedies under Australian Consumer Law.
Purchased Through an Authorised Cooly Bikes Dealer?
If you purchased your Cooly Bike through an authorised dealer, please contact that dealer in the first instance for assistance.
They will often be the quickest starting point because they have the original sale details and may be able to inspect the bike locally.
Cooly Bikes also remains available to assist with applicable warranty enquiries.
