Integrated dedicated front sprocket

AYA for E-BIKE central motor, torque shaft, central transmission, developed in line with the ISO safety
protection of the integrated beltpulley set, greatly optimized the assembly process of the tolerance, so the belt pulley axial and radial bias to achieve the optimal solution, belt tension is very stable, thereby increasing the life of the belt system. Its appearance and structure have independent intellectual property patents, the operation
life, fully meet and higher than ISO 4210-8, ISO 4210-2 requirements, the laboratory under the rated load of 80N .M, its up to 100,000 times from 0 to 30KM/H accelerated cycle, more than 10,000 kilometers of effective use. It
is more than 2 times the service life of the chain.
