REAR SPROCKETS

HRB series belt is specially designed for urban commuting wheel motor electric bicycle, ordinary flower drum bicycle development design; Its new composite rubber material,
combined with high-modulus carbon fiber core wire, wear-resistant teeth nylon canvas, compared to the traditional
chain, also has more than twice the service life and bring a clean riding experience.
-40℃~85℃ wide adaptation to temperature resistance, but also the basis for product stability

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.

HQB series belt is specially designed for the middle motor
electric bicycle below 75N.M development, its special
formula of high-performance composite rubber and plastic materials, combined with high modulus carbon fiber core
wire, wear-resistant teeth nylon canvas, compared with the
traditional chain, with more than 2 times the service life and bring clean riding experience.
-40℃~85℃wide adaptation to temperature resistance, but also the basis for product stability.

1.The two-way belt guides the side guard, effectively solving
the belt into the groove during operation andpreventing
falling off and jumping teethIntegrated protective disc in
accordance with ISO protection specifications.
2.The double-sided large-size hollow and double-side slope V-shaped design effectively solve the difficulty of fine sediment discharge during operation, thereby increasing the service life of the belt and pulley
