TAYA has developed a range of chains, from 11 speed to the IGH system, to deal with the greater torque and stress an e-bike delivers to the drivetrain. All current safety standards have been matched, plus the TAYA-DHT (Diamond Hard Treatment) means the chain components also have up to HK 2,000 hardness, prolonging the life of the chain. Testing has shown flawless compatibility with the Bosch series (350W, 75Nm), and the Yamaha series (500W, 80Nm), and the superior strength of the chains means they are approved for 1000W and 160Nm torque mid-drive systems. They are highly recommended for sporty pedelecs. Recommended for 10-speed e-bikes.
