You can register your HNF-NICOLAI bike for HNF PLUS within 90 days of purchase. In return, you are given an extended manufacturer’s warranty of five years on the frame. Registration is free of charge. We merely ask that you allow us to contact you for customer surveys – e.g. should we ever want to ask you about your experience with your bike. If we should make use of this possibility at all, this will in no case happen more than two or three times throughout your bicycle’s life.

By submitting your registration, our manufacturer’s warranty is extended for you from three to five years, with all other conditions remaining the same. In addition, by submitting your registration, you agree that we may contact you for customer surveys.
