Legal Disclaimer

Last Updated: October 20, 2026

This Legal Disclaimer applies to the Yolin website (https://yolintech.com/) and its published content, including product descriptions, technical specifications, manuals, installation guides, images, videos, and other informational materials.

Please read this Disclaimer together with our Terms of Service, Privacy Policy, Shipping Policy, and Return & Refund Policy.

1. General Information

Yolin provides electric bicycle accessories, electronic components, battery charging and storage solutions, and related technical information.

We make reasonable efforts to keep the information on this website accurate and up to date. However, product specifications, features, availability, and other details may change as products are updated.

Website content is provided for general informational purposes and should be read together with the applicable product documentation, safety instructions, and terms of sale. It does not replace professional technical advice or applicable legal requirements.

2. Product Compatibility

Yolin products are designed for specific applications and may be compatible with certain electric bicycle systems or components. Compatibility is not universal and may depend on the bicycle model, controller hardware and firmware, communication protocol, operating voltage, connector type, wiring configuration, and other technical factors.

Customers should review the relevant product specifications before purchasing. If compatibility is uncertain, please contact our support team with the product details, bicycle model, and clear photographs of relevant labels or connectors where appropriate.

Any compatibility guidance provided by Yolin is based on the information available at the time. Unless expressly confirmed for the specific configuration, compatibility with one model or product family does not guarantee compatibility with every version or modification of that model.

3. Installation, Modification, and Use

Customers must follow the applicable product manual, installation instructions, safety warnings, and maintenance requirements.

Improper installation, incorrect wiring, incompatible components, unauthorized modifications, or use outside the specified operating conditions may cause malfunction, equipment damage, electric shock, injury, or other hazards.

Where professional installation or technical expertise is required, customers should seek assistance from a suitably qualified professional. Customers must ensure that their installation and use of a product are appropriate for the intended application and comply with applicable laws.

Nothing in this section excludes or limits any responsibility that cannot lawfully be excluded.

4. Electric Bicycle Regulations

Electric bicycle laws and regulations vary by country, region, vehicle classification, and intended use.

In the European Union, certain pedal-assist cycles may qualify as EPACs when they meet the applicable requirements, including conditions concerning maximum continuous rated power and assistance cut-off speed. The legal classification of a complete bicycle depends on its overall configuration and the laws applicable in the relevant jurisdiction.

Installing or using a Yolin accessory does not, by itself, establish that the complete bicycle complies with all applicable requirements for road use, registration, insurance, or vehicle classification.

Customers are responsible for checking local requirements before installing or using components that may affect vehicle performance or operating parameters. They should also consider the suitability of the brakes, tires, motor, battery, drivetrain, and other relevant components.

Nothing in this Disclaimer authorizes any use prohibited by applicable law.

5. Battery Charging and Storage Safety

Certain Yolin products are designed to support the charging, storage, or management of rechargeable batteries, including lithium-ion batteries.

These products must be used only within their specified operating conditions and in accordance with the applicable product instructions.

A battery charging or storage cabinet must not be understood as eliminating all risks associated with lithium-ion batteries. Battery incidents may result from defective or damaged batteries, incompatible chargers, improper charging, misuse, or other conditions beyond the intended function of the product.

Customers must follow the safety instructions supplied with the battery, charger, and Yolin product, use suitable charging equipment, and observe all applicable ventilation, electrical, and environmental requirements.

Stop using equipment that shows signs of damage, abnormal heating, swelling, unusual odor, smoke, or other indications of a potential fault. Follow the applicable emergency instructions and contact the appropriate emergency services if necessary.

Actual protection depends on the product design, condition, installation, operating environment, and compliance with the supplied instructions. No safety accessory should be treated as a substitute for appropriate fire prevention and electrical safety practices.

6. Testing, Certifications, and Compliance

References to testing, certifications, declarations of conformity, or technical standards apply only to the specific product, model, component, configuration, or scope identified in the relevant documentation.

A test report or certificate for one product must not be interpreted as evidence that every Yolin product, a complete electric bicycle, or a modified vehicle has received the same approval or certification.

Customers should consult the relevant product page and supporting documentation to determine which tests, standards, or certifications apply.

All compliance statements are subject to the scope and validity of the relevant documentation and applicable legal requirements.

7. Product Information and Availability

Product images, illustrations, videos, and demonstrations are provided to help customers understand our products. Actual products may differ in minor visual details, packaging, or accessories due to product revisions.

We make reasonable efforts to ensure that product descriptions and specifications are accurate. Any material product characteristics, limitations, and safety information remain subject to the applicable product listing, documentation, and legal requirements.

Product availability, pricing, promotional offers, and delivery options may change. We reserve the right to correct genuine errors and update website information, subject to applicable law and any contractual rights already established.

8. Third-Party Websites and Resources

This website may contain links to third-party websites, software, technical resources, or external services for reference or convenience.

Yolin does not control all third-party content, policies, products, or services and cannot guarantee their accuracy, availability, or suitability. The inclusion of a link does not necessarily imply endorsement.

Customers should review the relevant third party's terms, privacy policy, and safety information before using its services.

9. Limitation of Liability

To the extent permitted by applicable law, Yolin shall not be liable for indirect or consequential losses arising from the use of, or inability to use, this website or its general informational content.

Nothing in this Disclaimer excludes or limits liability where such exclusion or limitation is prohibited by applicable law, including mandatory product liability, applicable consumer protection rights, or liability that cannot lawfully be excluded or limited.

This Disclaimer does not replace any applicable contractual obligations, statutory warranties, product safety obligations, or mandatory consumer rights.

10. Consumer Rights and Applicable Law

Customers may have mandatory rights under the consumer protection laws of their country or region, including rights relating to product conformity, statutory guarantees, withdrawal from distance contracts, refunds, repairs, or replacements where applicable.

Nothing in this Disclaimer is intended to waive, restrict, or diminish those rights.

The application of any law or jurisdiction to a transaction depends on the relevant circumstances, contractual terms, and applicable legal requirements. This Disclaimer does not, by itself, determine the governing law or jurisdiction for every transaction.

11. Updates to This Disclaimer

We may update this Disclaimer to reflect changes in our products, services, business practices, or applicable legal requirements.

The latest version will be published on this page with its updated date. Changes will take effect as permitted by applicable law and will not retroactively remove rights that have already accrued.
