Warranty and guarantee refer to two different types of claims. If an e-bike does not comply with the specified properties after purchase and has defects, the customer is entitled to a statutory warranty. The claim only applies if the defect is not self-inflicted. Wear parts have a special position in the warranty. Warranty claims remain valid even in warranty cases. The customer has a statutory warranty claim of 2 years. This applies to material, production and design defects. Batteries and electronic components are covered by a warranty of Since January 2022, the burden of proof in the first 12 months From purchase lies with the dealer/manufacturer. From the 13th month, the so-called "reversal of evidence" applies. Now the burden of proof lies with the consumer. Excluded from this are electronic components and batteries, here the reversal of the burden of proof already takes effect after 6 months.
