Düsenspeed GmbH – General Terms and Conditions and Warranty Terms

Version: 16 July 2026

Part A – General Terms and Conditions

1. Provider and scope

1.1 These General Terms and Conditions apply to contracts between:

Düsenspeed GmbH
Murtenstrasse 44
3179 Kriechenwil
Switzerland
UID: CHE-314.446.125
Email: info@duesenspeed.com

and its customers for products ordered directly from Düsenspeed GmbH. The product range includes in particular e-bikes, boats, bicycle and boat components, accessories, spare parts and individually configured or custom-made products.

1.2 Purchases made from an independent Düsenspeed specialist dealer are governed primarily by the purchase contract and the terms and conditions of the respective dealer. The voluntary manufacturer's warranty provided by Düsenspeed GmbH may apply in addition if its requirements are met.

1.3 Customers may be consumers or businesses. A consumer is a natural person who concludes the contract predominantly for private purposes. Mandatory statutory consumer protection provisions remain reserved in all cases.

1.4 Any deviating terms and conditions of the customer apply only if Düsenspeed has expressly agreed to them in writing.

2. Offers and conclusion of contract

2.1 Product presentations, technical information and prices on the website are provided for information and generally do not constitute a binding offer unless they are expressly designated as binding.

2.2 Enquiries, configurations and orders submitted by the customer constitute an application to conclude a contract. A contract is concluded only when Düsenspeed sends a written order confirmation. An automatically generated acknowledgement merely confirms receipt of an enquiry or order and does not constitute an order confirmation.

2.3 For individually configured or custom-made products, the specifications, equipment, prices and dates stated in the order confirmation are binding. The customer must check this information carefully before approving it.

2.4 The version of these General Terms and Conditions in effect when the respective contract is concluded applies. Subsequent amendments do not apply retroactively to contracts already concluded.

2.5 Düsenspeed may reject an order for objective reasons, in particular if a product is unavailable, a price is obviously incorrect, a payment check fails or there is reasonable suspicion of fraud. Payments already made will be refunded in such cases.

3. Product information and individual manufacture

3.1 Düsenspeed endeavours to provide complete and accurate product representations. Minor differences in colours, surfaces and handcrafted parts may result from screen display, material characteristics or production and do not constitute a defect, provided that the agreed characteristics and function are not materially impaired.

3.2 Technical changes are permitted if they are required due to further development, component availability or legal requirements, do not materially impair the agreed function and are reasonable for the customer. Material changes require the customer's consent.

3.3 Information concerning range, performance, weight, charging time, speed, riding or sailing characteristics depends on equipment, use, load, temperature, terrain, waters, weather, tyre pressure, battery and material condition and other circumstances. A particular characteristic is guaranteed only if it is expressly designated as binding in the order confirmation.

4. Prices and additional costs

4.1 For deliveries to consumers in Switzerland, prices are stated in Swiss francs (CHF), including legally payable value-added tax and all mandatory surcharges. Shipping or delivery costs are stated separately before the contract is concluded.

4.2 The price stated in the written order confirmation applies to individually manufactured products. Subsequent change requests may result in additional costs and changes to the delivery date. Düsenspeed will inform the customer before carrying out such changes and obtain the customer's consent.

4.3 For deliveries abroad, the customer is responsible for any additional import taxes, customs duties and official charges unless expressly agreed otherwise in the offer. Düsenspeed declares shipments truthfully and will not artificially reduce the declared value of goods.

5. Payment

5.1 The available payment methods and due dates are specified in the offer, ordering process or order confirmation. Unless otherwise agreed, the full purchase price must be paid before shipment or handover.

5.2 For custom-made products, Düsenspeed may require a deposit and further instalments linked to agreed project or manufacturing stages. The amounts and due dates are specified in the order confirmation.

5.3 In the event of late payment, Düsenspeed may issue a reminder, set a reasonable grace period, suspend further performance and enforce the consequences of default permitted by law. Reminder and collection costs will be charged only to the extent that they were actually incurred, necessary and legally permissible.

5.4 Düsenspeed may conduct proportionate security checks and request the necessary evidence to prevent payment fraud. The person concerned will be informed about the related processing of personal data. If an order cannot be sufficiently verified, Düsenspeed may cancel it; any payment already made will be refunded.

6. Custom-made products, cancellations and changes

6.1 A product is considered custom-made if it is manufactured, painted, assembled, adapted or specifically procured according to individual specifications for the customer.

6.2 Once the written order confirmation has been sent, custom-made products cannot be returned or cancelled under any voluntary right of return or cancellation. Statutory rights in the event of defects, delivery delays or any other breach of contract remain unaffected.

6.3 Düsenspeed may agree in writing to a requested cancellation as a gesture of goodwill. There is no entitlement to such agreement. The conditions of any cancellation are determined in writing on a case-by-case basis. Work already performed, specially procured materials, third-party services and other demonstrably incurred and unavoidable costs may in particular be taken into account, up to the agreed total price.

6.4 Change requests must be submitted to Düsenspeed in text form and become effective only upon written confirmation. They will be considered where technically and organisationally possible. Düsenspeed will inform the customer of any additional costs and effects on the delivery date before implementation. No chargeable changes will be carried out without the customer's consent.

7. Delivery, collection and delivery dates

7.1 Delivery periods for individually manufactured products are estimates unless a date has expressly been confirmed as binding in writing. The period begins only once all technical details have been clarified, all required approvals have been given and any agreed deposits have been received.

7.2 Düsenspeed will inform the customer of any foreseeable material delay. Statutory rights in the event of delayed delivery, including the right to set a reasonable grace period, remain reserved.

7.3 Events beyond Düsenspeed's reasonable control, including natural events, official measures, war, strikes, failure of critical suppliers or transport disruptions, extend the performance period by a reasonable amount. If the impediment continues for so long that it is no longer reasonable for a party to remain bound by the contract, either party may terminate the unperformed part of the contract. Amounts already paid for services not provided will be refunded.

7.4 The shipping method, delivery location and costs are specified during the ordering process or in the order confirmation. For consumers, benefit and risk pass to the customer or to a person authorised by the customer to receive the product when the product is handed over. Mandatory statutory provisions remain reserved.

7.5 Visible transport damage should, where possible, be documented upon receipt and reported to Düsenspeed promptly. Failure to submit such a report does not affect mandatory statutory rights relating to defects.

8. Voluntary right of return for stock items

8.1 Swiss law does not provide a general right of withdrawal for ordinary online purchases. Düsenspeed voluntarily grants a right of return within 10 calendar days of receipt for stock items purchased directly from Düsenspeed that were not individually manufactured.

8.2 The return must be registered with Düsenspeed by email before shipment. Düsenspeed will then provide the return address and required information. Registration is intended to ensure orderly processing and does not restrict statutory rights relating to defects.

8.3 The item must be returned complete, unused and undamaged. Inspection comparable to that permitted in a retail shop is allowed. Düsenspeed may make an appropriate deduction for any loss in value resulting from handling beyond such inspection. The original packaging should be used where reasonably possible.

8.4 The customer bears the direct costs and transport risk of a voluntary return. Following receipt and inspection, the refundable purchase price will generally be reimbursed using the original payment method. Special or more expensive shipping methods and additional services already provided will not be refunded.

8.5 Custom-made products are not accepted for return. The voluntary right of return excludes in particular:

  • individually configured, manufactured, painted or adapted products;
  • items procured specifically at the customer's express request;
  • components that have already been installed, used or damaged;
  • opened sealed items that are not suitable for return for health or safety reasons;
  • consumables and wear parts once they have been used.

8.6 These exclusions do not apply to justified claims relating to a defect. Items purchased through a specialist dealer must be returned through that dealer.

9. Statutory rights relating to defects

9.1 For direct sales, Düsenspeed is responsible for ensuring that the product has the agreed characteristics upon handover and is free from defects that materially reduce its value or suitability for its intended use.

9.2 The customer should inspect the product to a reasonable extent after receipt and report identifiable defects without undue delay. Defects discovered later must be reported without undue delay after discovery. The report should include the purchase receipt, serial or frame number, a description and, where possible, meaningful photographs.

9.3 Claims relating to defects in new products under consumer contracts become time-barred no earlier than two years after delivery. Any mandatory longer periods remain reserved.

9.4 In the event of a justified defect, Düsenspeed may repair the defect free of charge within a reasonable period or replace the product or affected component with an equivalent version. If repair or replacement is impossible, disproportionate, has repeatedly failed or cannot reasonably be accepted by the customer, the customer may request an appropriate price reduction or, in the case of a material defect, rescission of the purchase contract. Mandatory statutory rights remain reserved.

9.5 No defect exists to the extent that an impairment is attributable to:

  • normal wear or the normal loss of battery capacity;
  • accident, fall, overloading or improper transport;
  • use contrary to the operating instructions or safety information;
  • insufficient or improper maintenance;
  • unauthorised technical modifications, performance enhancements or installation of incompatible parts;
  • unsuitable cleaning agents, pressure washers or other damaging influences;
  • external influences for which the product was not designed.

An exclusion applies only to the extent that the relevant circumstance caused or contributed to the reported damage or defect.

9.6 Components made by other manufacturers may be covered by additional warranties from the respective manufacturer. This does not restrict statutory claims arising from a direct purchase contract with Düsenspeed.

10.1 The customer must observe the operating instructions, safety information, maintenance requirements and the road traffic, navigation, environmental and approval regulations applicable at the place of use.

10.2 The pre-delivery inspection, commissioning and safety-relevant basic settings must be performed by Düsenspeed or qualified specialist personnel. Depending on the product, this includes in particular brakes, suspension, drive, motor and battery systems, steering, controls, rigging and other safety-relevant equipment. Subsequent maintenance and repair work on such parts must also be performed by qualified specialist personnel.

10.3 Products or operating modes that are not approved for public roads or specific waters must not be used there. Unauthorised interference with speed limits, motor controls or other safety-relevant systems is prohibited.

10.4 These obligations do not release Düsenspeed from its mandatory legal obligations as manufacturer or seller, particularly in relation to product safety.

11. Liability

11.1 Düsenspeed has unlimited liability wherever liability cannot legally be excluded or limited. This applies in particular to intent or gross negligence, injury to life, body or health and claims under product liability legislation.

11.2 In the event of a slightly negligent breach of material contractual obligations, Düsenspeed is liable for the type of loss that was reasonably foreseeable when the contract was concluded. In all other respects, liability for slight negligence is excluded to the extent permitted by law.

11.3 Düsenspeed is not liable for losses demonstrably caused by unlawful or improper use, an unauthorised technical modification or disregard of clear safety and maintenance instructions.

11.4 Mandatory statutory liability provisions remain reserved in all cases.

12. Data protection

12.1 Düsenspeed processes personal data for the initiation and performance of contracts, customer service, security checks and compliance with legal obligations. Details are provided in a separate privacy policy that is easily accessible on the website.

12.2 Advertising by email or comparable electronic channels is sent only within the legally permissible framework. Consent may be withdrawn at any time with effect for the future.

13. Final provisions

13.1 If any provision of these General Terms and Conditions is wholly or partly invalid, the remaining provisions remain effective to the extent that continued adherence to the contract is reasonable. The statutory provisions apply in place of an invalid provision. An invalid clause is not automatically replaced by a similar provision that is less favourable to the customer.

13.2 Swiss law applies, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods (CISG). For consumers, mandatory protective provisions of the state of their habitual residence remain reserved to the extent that they apply.

13.3 Mandatory statutory places of jurisdiction apply to disputes involving consumers. For contracts with businesses, the courts at the registered office of Düsenspeed GmbH in Kriechenwil have jurisdiction to the extent permitted by law.

Part B – Voluntary Manufacturer's Warranty

1. Relationship to statutory rights relating to defects

1.1 The following manufacturer's warranty is an additional voluntary service provided by Düsenspeed GmbH. It does not restrict statutory rights relating to defects against the respective seller.

1.2 In the case of a direct purchase from Düsenspeed, statutory rights relating to defects may be asserted independently of this warranty. In the case of a purchase through a specialist dealer, statutory rights relating to defects are directed against the respective dealer; the additional manufacturer's warranty is provided by Düsenspeed under the following terms.

1.3 In accordance with Düsenspeed's previous warranty terms, the voluntary manufacturer's warranty is available to the original end purchaser upon presentation of the original purchase receipt. The warranty cannot be transferred to a subsequent owner without Düsenspeed's prior written consent.

2. Warrantor and covered products

The warrantor is:

Düsenspeed GmbH
Murtenstrasse 44
3179 Kriechenwil
Switzerland
UID: CHE-314.446.125
Email: info@duesenspeed.com

2.1 The warranty covers new Düsenspeed bikes and products manufactured by Düsenspeed or designated as Düsenspeed bicycle components that were purchased directly from Düsenspeed or from an authorised Düsenspeed specialist dealer.

2.2 There is currently no generally defined voluntary manufacturer's warranty for boats and boat components. Statutory rights relating to defects and any warranties expressly granted by Düsenspeed in the respective order confirmation apply.

2.3 Components made by other manufacturers are not covered by this voluntary Düsenspeed manufacturer's warranty. They may be covered by warranties from the respective manufacturer. Statutory rights relating to defects against the seller remain unaffected.

3. Warranty period

The warranty begins upon documented handover to the first purchaser. The following warranty periods apply:

  • complete Düsenspeed bike: 2 years;
  • frame manufactured by Düsenspeed: 7 years;
  • paint finish applied by Düsenspeed: 2 years;
  • battery: 1 year for at least 75 percent of the original usable capacity. Testing is carried out by Düsenspeed or an authorised Düsenspeed specialist dealer using a suitable and verifiably documented diagnostic or capacity measurement procedure, taking the manufacturer's technical specifications into account.

The one-year voluntary battery capacity warranty does not restrict statutory rights relating to defects, particularly in the event of a technical battery defect.

4. Warranty service

4.1 If a covered product has a proven material, design or manufacturing defect within the warranty period, Düsenspeed will decide following a technical assessment whether to repair the product or affected component or replace it with a technically equivalent version.

4.2 A replacement may differ in model, colour or version if the original product is no longer available and the replacement is technically and economically equivalent and reasonable for the customer.

4.3 Düsenspeed bears the labour and material costs required for an approved warranty service. Transport, removal and installation costs are covered where Düsenspeed has approved them in advance or where processing takes place through Düsenspeed or a specialist business designated by Düsenspeed.

4.4 A component repaired or replaced under this warranty is covered for the remainder of the original warranty period, but for at least 12 months after return. If a complete bike is replaced with a new bike, a new warranty period under these terms begins for the replacement bike.

5. Warranty exclusions

The voluntary manufacturer's warranty does not apply to the extent that the damage or defect was caused or contributed to by:

  • normal wear or wear resulting from intended use;
  • accident, fall, improper transport, overloading or external force;
  • use contrary to the operating instructions, safety information or intended purpose;
  • insufficient or improper maintenance, where this caused the damage;
  • repairs performed by unqualified persons;
  • modifications, drilling, repainting, software interventions or performance enhancements not approved by Düsenspeed;
  • installation of incompatible or safety-relevant components that have not been approved;
  • unsuitable cleaning or care products, pressure washing, corrosion due to improper storage or other damaging external influences;
  • commercial rental unless such use was agreed in writing;
  • removed or illegible frame, serial or identification numbers.

6. Wear parts

Wear parts are excluded from the warranty only if the complaint results from normal wear. A material or manufacturing defect remains covered by the warranty even for a wear part.

Typical wear parts include in particular:

  • brake pads and brake discs;
  • tyres and inner tubes;
  • chains, chainrings, cassettes and sprockets;
  • bearings, bushings, seals, O-rings and dust seals;
  • grips and handlebar tape;
  • gear and brake cables, including outer housings;
  • springs, suspension elements and their moving seal or rubber parts;
  • freehub bodies;
  • spokes;
  • mudguards and chain guides.

7. Making a warranty claim

7.1 Warranty claims must be reported promptly after discovery of the issue:

  • for a direct purchase: to Düsenspeed;
  • for a purchase from an authorised specialist dealer: generally to that specialist dealer.

7.2 The purchase receipt, frame or serial number, a comprehensible description of the issue and, where possible, photographs or videos are required for assessment. Düsenspeed may require the product or affected component to be provided in a clean condition for technical inspection.

7.3 Products must not be sent in and chargeable work must not be performed until agreed with Düsenspeed. Prior agreement ensures correct processing and does not restrict mandatory statutory rights.

8. Applicable law and jurisdiction

This manufacturer's warranty is governed by Swiss law. Mandatory statutory places of jurisdiction and applicable mandatory protective provisions remain reserved for consumers. For businesses, the courts at the registered office of Düsenspeed GmbH in Kriechenwil have jurisdiction to the extent permitted by law.
