Revolve is a company that was created to sell electric vehicles. All vehicles are powered by batteries. Prior to launching these products, management of Revolve devoted extensive time assuring quality. To accomplish this mission, we have visited our suppliers of batteries and bicycles to ascertain that quality is uppermost in their minds. We have ordered production models from potential manufacturers and subjected the bikes and vehicles to rigorous tests before accepting these manufacturers as suppliers. Every product comes with a warranty with regard to certain parts. Parts such as brakes and wheels which are subjected to normal wear and tear are not covered by warranties.
