Our bikes use branded electric cells and can still provide 60% capacity after 500 full charge-depletion cycles if taken care of properly. The battery life is highly dependent on how you take care of it, we have prepared a guide on the topic.
If the battery goes dead within the 2-year warranty period, we can provide you with a replacement for free. If the battery is outside of warranty, you can still purchase a replacement from us by contacting firstname.lastname@example.org. The cost will be less than 200 Euros.
We would recommend you replace the battery with our provided guide at a trusted local bike shop, and we will reimburse the cost within the warranty.
