EBG Primary Drive Front & Rear Pulley V2

EBG Primary Drive Pulley Kit V2Primary Drive Pulley Kit for SurRon, Talaria, ERide Pro & Compatible Electric Dirt BikesThe EBG Primary Drive Pulley Kit V2 is a complete primary belt drive upgrade designed for the SurRon Light Bee X. The kit combines a CNC-machined 7075-T6 aluminum rear pulley hub, a high-hardness heat-treated 420J2 stainless steel rear pulley ring, a CNC-machined stainless steel front pulley, and an EBG carbon fiber reinforced drive belt.The hybrid pulley construction reduces rotating mass while maintaining high structural rigidity and wear resistance. Precision CNC machining and controlled manufacturing tolerances ensure accurate belt alignment, consistent tooth engagement, and reliable operation under high-load riding conditions.Package Includes• 1 × EBG CNC Hybrid Rear Pulley • 1 × EBG CNC Stainless Steel Front Pulley • 1 × EBG Carbon Fiber Reinforced Belt (18 mm or 20 mm)Outstanding FeaturesHybrid 2-Piece Rear PulleyThe rear pulley utilizes a two-piece hybrid construction consisting of a CNC-machined 7075-T6 aluminum hub and a high-hardness heat-treated 420J2 stainless steel pulley ring.The lightweight aluminum hub reduces rotational inertia, while the hardened stainless steel tooth profile improves wear resistance and maintains tooth geometry during extended operation.Features:• Hybrid 2-piece pulley construction • CNC-machined 7075-T6 aluminum hub • Heat-treated 420J2 stainless steel pulley ring • Reduced rotating mass • High strength-to-weight ratio • Improved wear resistance • Long service lifeCNC 7075-T6 Billet Aluminum HubThe rear pulley hub is CNC machined from aerospace-grade 7075-T6 billet aluminum and extensively pocketed to reduce weight without compromising strength.Its aggressive multi-level machining creates a distinctive three-dimensional appearance while minimizing rotational mass for improved drivetrain response and efficiency.Finished with a premium anodized coating for enhanced corrosion resistance and long-lasting appearance.Features:• CNC Billet 7075-T6 Aluminum • Aggressive Lightweight Pocketing • High Strength-to-Weight Ratio • Multi-Level CNC Machining • Premium Anodized FinishCNC Stainless Steel Front Pulley & Rear Pulley RingThe front pulley is CNC machined from heat-treated 420J2 stainless steel to provide improved wear resistance compared to conventional aluminum pulleys.The hardened tooth profile maintains accurate belt engagement and minimizes tooth wear during continuous operation.Features:• CNC-machined 420J2 stainless steel • Heat-treated for increased surface hardness • High wear resistance • Corrosion resistant • Long service lifeAdvantages:• High-hardness heat-treated 420J2 stainless steel • Exceptional wear resistance • Superior durability • High load capacity • Corrosion resistant construction • Extended service lifeEBG Carbon Fiber Reinforced BeltThe kit includes EBG’s premium carbon fiber reinforced drive belt, available in both 18 mm and 20 mm widths.Designed for smooth and efficient power transfer, the belt delivers exceptional tensile strength while reducing drivetrain noise and maintenance requirements compared to traditional chain systems.Available Options:• 18 mm Carbon Fiber Reinforced Belt • 20 mm Carbon Fiber Reinforced BeltBenefits:• High tensile strength • Smooth and quiet operation • Excellent flexibility • Long service life • Low maintenancePrecision CNC ManufacturingEvery component is precision CNC machined to tight tolerances, ensuring perfect alignment, consistent belt engagement, and maximum drivetrain efficiency.The combination of lightweight 7075-T6 aluminum, high-hardness heat-treated 420J2 stainless steel, and carbon fiber reinforcement creates a premium primary drive system engineered for both everyday riding and high-performance applications.Technical SpecificationsComponentMaterialRear Pulley HubCNC Billet 7075-T6 AluminumRear Pulley RingHigh-Hardness Heat-Treated 420J2 Stainless SteelFront PulleyHigh-Hardness Heat-Treated 420J2 Stainless SteelDrive BeltCarbon Fiber ReinforcedBelt Width18 mm / 20 mmFinishPremium Anodized (Hub)ManufacturingPrecision CNC MachinedCompatibility• SurRon Light Bee X (LBX)• Talaria XXX • ERide Pro • 79Bike Falcon Pro / GT / M • Ventus One / One Plus • Segway X260Why Choose EBG V2?✔ Complete primary belt drive upgrade kit✔ Advanced hybrid 2-piece rear pulley design✔ Aerospace-grade 7075-T6 billet aluminum hub✔ High-hardness heat-treated 420J2 stainless steel front pulley and rear pulley ring✔ Carbon fiber reinforced drive belt✔ Reduced rotating mass for improved drivetrain response✔ Exceptional wear resistance and extended service life✔ Premium multi-level CNC machining✔ Smooth and efficient power transfer✔ Precision engineered by EBGInstallation Notes• Direct replacement for the OEM primary drive system. • Verify proper belt alignment and tension before riding. • Inspect all fasteners after the first 50 km. • Periodically inspect the belt and pulley teeth for wear.
