We expressly point out that e-bike tuning products may only be used in private, enclosed areas. For example, for sporting competitions and advertising purposes. E-bike tuning is not permitted under road traffic regulations. Use is at your own risk. We assume no liability whatsoever for any current or future damage to property and/or persons resulting from improper installation, fitting, and/or use. The warranty on your e-bike will be limited or completely voided by the use of tuning products, as the installation or use of e-bike tuning constitutes a modification or manipulation of your e-bike. If your e-bike has a type approval, this will generally also be invalidated. Please always ride carefully, wear protective clothing such as helmets or protectors, and do not endanger yourself or others. Please also note that some manufacturers use analysis software to detect sensor data manipulation and may permanently store and later evaluate this data. Since the offered tuning products operate on the principle of speed manipulation, such logging cannot be ruled out even after subsequent firmware updates. No liability is assumed for any resulting damage. Please only use the product if you are aware of this! Operation on public roads is expressly prohibited by the German Road Traffic Regulations (StVO)! Violation may result in prosecution for driving without a license (§21 StVG) and/or driving without insurance (§6 PflVG). The same applies to the loss of accident victim assistance. The existing components/materials of the wheel used may not be designed for continuous use with the tuning product. Please inquire about the current legal status and any potential consequences of installation before using the system. The consumer is aware that any tuning or optimization of their vehicle can affect its lifespan and performance. The standard characteristics will be altered in any case.
