Warranty policy
This page explains how warranty coverage is identified, what information may be required, and how to request assistance for a SISMA Bike purchase.
Last updated September 3, 2026Use the written warranty supplied or displayed for your exact model.
Your order information and serial number help us review eligibility.
Wait for instructions before returning a bike, battery, or component.
Warranty duration, covered components, eligibility, exclusions, and available remedies can differ by product. Review the warranty shown on the product page and any warranty document or manual supplied with the item. This general page explains SISMA’s claim process and does not expand or replace those model-specific terms.
01 / Scope
Who and what this page applies to
This policy applies to products purchased directly from SISMA Bike and supported by valid proof of purchase. If a manufacturer or another identified company is the warrantor, its written warranty determines the coverage and remedy. Products purchased from another seller must be handled through that seller or the warrantor named in the applicable documents.
We may request the purchaser’s name, order number, product model, serial number, delivery information, and evidence showing the reported issue to verify the purchase and evaluate the request.
02 / Coverage
What a product warranty may cover
When a product-specific written warranty applies, it may provide a remedy for a covered defect in materials or workmanship that appears during its stated warranty period under normal, intended use. The written warranty for the exact model identifies:
- The company providing the warranty.
- Whether the warranty is designated full or limited.
- The coverage period and when that period begins.
- The components, conditions, and purchasers that are eligible.
- The procedure and available remedy for an approved claim.
Descriptions, estimates, and general guidance on this page do not create coverage beyond the applicable written warranty or rights provided by law.
03 / Exclusions
Conditions that may not be covered
Subject to the product-specific terms and applicable law, warranty coverage generally does not apply when the reported problem results from:
- Normal wear, cosmetic change, routine adjustment, or ordinary maintenance.
- Collision, impact, abuse, misuse, overloading, racing, stunt riding, or use outside the product’s intended purpose.
- Incorrect assembly, maintenance, storage, charging, transportation, or repair.
- Flooding, submersion, high-pressure washing, corrosion, fire, extreme heat, freezing conditions, or another external event.
- Modification or installation of a part, accessory, firmware, or electrical component that causes or contributes to the failure.
- Continued operation after a warning, visible defect, unusual sound, excessive heat, or other indication that use should stop.
- A removed, altered, obscured, or unreadable serial number when that prevents verification.
Third-party service and parts
Using an independent repair provider or a third-party part does not by itself cancel legal warranty rights. However, damage caused by an incorrect part, incompatible accessory, improper installation, or deficient repair may not be covered.
04 / Battery care
Battery-specific considerations
Battery coverage and capacity requirements are defined by the written warranty for the applicable model. Battery performance naturally changes with time, use, charging patterns, temperature, and storage conditions; the product-specific terms determine whether a reported capacity change qualifies for warranty review.
Use only an approved, compatible charger and follow the manual for charging and storage. Damage related to an incompatible charger, modification, impact, water entry, extreme temperature, neglected storage, opened battery housing, or improper electrical work may be excluded when it causes or contributes to the problem.
05 / Claim process
How to request warranty assistance
Stop using the product if continued operation could cause injury or further damage. Photograph or record the issue before changing the bike.
Prepare the purchaser name, order number, model, serial number, delivery date, description of the issue, and clear photos or video.
Email support@sismabike.us and explain when the issue began, the conditions in which it occurred, and any troubleshooting already completed.
We may request additional evidence, safe troubleshooting, inspection, or return authorization. Do not disassemble or ship a bike, battery, or component unless instructed.
06 / Review and remedy
What happens after submission
Submitting a request does not automatically establish warranty eligibility. SISMA or the identified warrantor will review the purchase information, reported condition, evidence, product history, and applicable written terms. Additional diagnostics or inspection may be required.
If the claim is approved, the remedy will follow the product-specific warranty and applicable law. Depending on those terms and the circumstances, a remedy may involve troubleshooting, repair, a replacement component, product replacement, or another stated resolution.
Labor, transportation, and shipping costs
The applicable written warranty determines which labor, removal, installation, packaging, transportation, and shipping costs are covered. Unauthorized expenses or returns sent without instructions may not be reimbursed.
07 / Legal rights
Rights that may apply to you
This policy and any product-specific written warranty are in addition to rights and remedies that cannot lawfully be excluded or restricted. Implied warranty rights and other consumer protections vary by state and jurisdiction. Nothing on this page is intended to waive a right that applicable law does not allow a seller or warrantor to waive.
Returns that are not based on an eligible warranty claim are governed by the SISMA refund policy. Delivery matters are also subject to the shipping policy, and general site and purchase conditions appear in the terms of service.
