You will need at least basic mechanical skills and tools to build and use Qulbix products. Especially electrical equipment/components should be handled with care and according to manuals. If you feel you don't have the sufficient knowledge or the appropriate tools needed, you should let a skilled professional build and service your e-bike or other DIY products. When using performance e-bikes you should always read and act according to provided manuals and ride taking care of yourself and others.
