What to know when mounting lights on e-bikes
Note: StV(Z)O regulations apply only in Germany and do not apply elsewhere. Please consult with your local municipality for information regarding public safety regulations.
First and foremost, make sure you’re even allowed to change/mount lights on your e-bike*. According to German Road Traffic Regulations (StVO), a standard e-bike is totally equivalent to a bicycle. It does, however, fall under the so-called Machinery Directive, meaning certain guidelines apply when replacing individual parts such as lighting components. We have a guide concerning legal aspects of mounting accessories to an e-bike as well as a guide for component exchange developed by several bicycle associations (in cooperation with the Zedler Institute for bicycle technology and safety) available for download. These can give you a more accurate representation of the situation.
It should also be noted that installing or replacing lighting on an e-bike is sometimes much more complicated than on motor-less bikes. Errors can have more serious consequences and void a manufacturer's warranty. If you do not possess the necessary experience in electrical or automotive engineering to modify your e-bike yourself, we advise bringing it to a specialist workshop.
* By “e-bike” we mean the pedelec, which boosts pedal power up to 25 km/h. This applies to almost all electric bikes sold today. The term “e-bike” is therefore firmly established.
