Tooling costs are easily one of the most expensive investments to mass produce bicycle and e-bike frames in steel, aluminum alloy, or carbon fiber; rigid carbon fiber forks; and various components. Almost any product will require some sort of tooling for mass production. When creating a product that requires tooling, make sure to retain Oerus to handle due diligence and exercise quality control to ensure that tooling meet requirements. If you paid for the tooling costs, the instruments belong to you. Take the time to ensure they are well maintained and secure.
