Nobody is perfect !
We are happy that the fail rate of our products is already down to about 1 %, but  nothing and nobody is perfect. It is sometimes happen that there is an issue with a product, what result from a bad electronic part or a wrong wiring. However,  in a case of an issue we don´t point with a finger to somebody, we just want to solve the issue and help you to bring your bike back on the road again asap. That´s why we made this rma formular (pdf) what you should download and send it together with the defect part to us. Our response time is usually one working day if the product comes with this formular in our workshop.

Here you can download the EU conformity formular for our products.
