A warranty form sounds simple: you fill it out and your problem is solved.
In practice, it is primarily the starting point of a warranty application, in which you record what's going on, when it was created and what proof you can provide.
In this blog, we explain what a warranty form covers, what exactly it does not cover, and how to avoid unnecessarily delaying a claim.
What is a guarantee form (and what is it not)?
A warranty form is a document or online application you use to make a warranty claim with the seller or manufacturer.
The form itself is not an “additional guarantee” and it does not change the conditions.
Think of it as a structured way to gather all the information needed to assess whether the problem is covered under warranty.
Why does the guarantee form exist?
Warranty almost always involves three questions: is there a defect, is it within the time limit, and is the defect not caused by improper use or wear and tear.
With a form, you can answer those questions faster.
That's nice for you, as well as for the party that has to handle it.
What does a warranty form cover: the gist
The most important nuance: a warranty form does not “cover” anything on its own.
What people mean by the question what does a warranty form cover, is: what types of problems can you report with it that can usually be covered under warranty.
Most situations involve manufacturing or material defects that manifest themselves during normal use.
Typical issues that can often be covered under warranty
The exact coverage depends on brand, product type and conditions.
Yet when it comes to (electric) bicycles and e-mobility, you often see the same categories.
- Manufacturing defects in parts that are not supposed to fail due to wear and tear.
- Material defects (e.g., a part that cracks or breaks during normal use).
- Electronics failing without external cause, such as an error in operation/display.
- Engine or drive problems that cannot be traced to water/fall damage or improper maintenance.
- Battery problems that are beyond normal degradation (e.g., sudden failure).
A warranty form is designed to describe this type of complaint completely so that a quick diagnosis can be made.
What is usually asked on the form though
Many forms ask for the same basic information.
These seem administrative, but often determine whether your claim can proceed immediately.
- Name and contact information.
- Product data (model, frame number/serial number, date of purchase).
- A clear description of the complaint (what exactly is happening, when, how often).
- Photos and/or videos of the problem.
- Proof of purchase (invoice/receipt).
What exclusions do you often encounter?
Almost every warranty has limitations.
Those exclusions are not there to be troublesome, but to guard the difference between defect and use damage.
Those who know the exclusions can better substantiate their request or more quickly seek another solution (e.g., service or insurance).
Wear parts: the gray area
Wear and tear is one of the most common reasons for rejection or additional payment.
Under normal conditions of use, certain parts simply wear out.
- Brake pads and discs.
- Tires and tubes.
- Chain/sprocket or other transmission parts (depending on type of drive).
- Bearings, cables, grips and saddle (cover) if they are normal wear.
Important: Wear can sometimes accelerate due to an error, such as an incorrectly assembled part or a manufacturing error.
This is why good description and imagery is so important.
Damage due to use, accident or external factors
Warranty usually does not cover outside damage.
Consider a fall, collision, blow over, transportation damage or vandalism.
- Fall and impact damage (scratches, dents, warped parts).
- Water damage due to improper cleaning (e.g. high-pressure spray) or immersion.
- Damage due to improper storage (prolonged outdoors in extreme conditions).
For this type of risk, an appropriate policy often makes more sense.
For that, check out the options on the page insurance for your e-bike or fatbike.
Improper maintenance or failure to take timely action
A defect that gets worse because you continue driving may be (partially) out of warranty.
Overdue maintenance can also play a role.
- Continue driving with brakes on or play in bearings.
- Driving for too long with an abnormal sound without checking.
- Incorrect lubricants or improper adjustment due to unauthorized repair.

Proprietary modifications and tuning
Adjustments can make assessment more difficult.
E-bikes and fatbikes often involve software changes or non-original parts that alter the load.
- Boosting or manipulation of speed limitation.
- Non-original electronics or batteries.
- Parts that do not fit the specifications causing damage.
What evidence makes your warranty claim strong?
Warranty is not just about “I have a problem,” but also about “I can show what is happening.”.
Good evidence reduces the chances of back-and-forth emailing.
It makes assessment more objective and faster.
Make your complaint measurable and repeatable
A technician or service desk can do more with facts than with general terms like “is doing weird.”.
Write down exactly what you notice.
- When does the problem occur (on acceleration, in rain, after 10 km)?
- How often does it happen (always, sometimes, only in position 5)?
- What happened immediately before (drop, stall, maintenance, software update)?
Photos and videos: here's how to do it smartly
Photos from one angle are often insufficient.
A short video can save a lot of time, especially with noises or trouble codes.
- Film the problem in one take, with view of display/control.
- Take close-ups as well as overview photos.
- Record serial/frame number if requested.
Proof of purchase and details
Without proof of purchase, warranty is often difficult to assess.
Therefore, always keep your invoice and note the frame number.
If you need documents or manuals, check out documents and downloads.
Warranty vs. legal rights: what about it?
In addition to commercial warranty, as a consumer you also have legal rights around conformity.
In plain language: a product must do what you can reasonably expect of it.
This is separate from a “warranty certificate,” although in practice the routes often intertwine.
Why this is relevant in a warranty form
A warranty form is sometimes used for both warranty and conformity claims.
The questions are similar: purchase date, defect description, proof.
What is the process after filling out?
Submission is usually followed by a check for completeness.
It is then determined whether diagnosis is needed, or whether the problem is immediately recognizable as a warranty case.
More complex complaints may require inspection before a decision is made.
Possible outcomes
The assessment can go several ways.
It helps to know in advance what to expect.
- Repair under warranty: part will be repaired or replaced free of charge.
- Replacement: in the event of a non-repairable defect, all or part of the product may be replaced.
- No warranty, but service: repair can still be done for a fee.
- Referral: sometimes a dealer or specialist is needed for diagnosis.
Practical checklist: this is how to fill out the warranty form properly
Using the checklist below will increase your chances of a quick, clear resolution.
It usually saves at least one extra round of mail.
- Check purchase date and attach your invoice/receipt.
- Write the complaint in one sentence, then elaborate with details.
- Name conditions: rain, cold, heavy loading, storage.
- Take clear pictures and preferably a short video.
- List error codes or flashing patterns verbatim.
- Note what you have already tried (reset, charge, different battery if possible).
Common mistakes that cause delays
Some applications get bogged down by minor omissions.
These are easy to avoid.
- No or illegible proof of purchase.
- Incomplete serial number or incorrect model listed.
- Too vague complaint description without circumstances.
- Pictures without context or without detail.
- Repairs or adjustments made without reporting.
Where do you file your claim?
If you want to start your warranty request right away, use the official form.
This ensures that all required fields are included immediately.
Go to the warranty form and fill it out as completely as possible.
Finally, make warranty especially easy on yourself
A warrant form is the tool to bring together facts, evidence and context.
The more concrete you are, the faster the assessment can be.
If you have doubts about whether your situation is covered by warranty, service or insurance, it's best to fill out the warranty form and add your information; that way the team can coordinate the proper route with you.
