Key Features

100% Direct OEM Fit
This chain drive kit is precision-engineered to match the factory tooth counts, mounting points, and specifications of the Surron Ultra Bee. It installs directly with no modification required, ensuring perfect alignment and function.

Heavy-Duty Construction
Sprockets: Made from high-grade steel with a corrosion-resistant zinc coating, designed to resist wear and deformation under high torque loads.
Chain: Heavy-duty gold-plated chain with solid pins and rollers, offering superior strength, flexibility, and rust resistance compared to standard chains.

Optimized Gearing
The kit uses factory-matched tooth counts for the primary drive, ensuring the correct gear ratio for reliable power transfer, smooth acceleration, and consistent top speed. This eliminates the risk of misalignment or performance issues from mismatched parts.

Corrosion-Resistant Finish
The gold-plated chain and zinc-coated sprockets provide excellent protection against rust and corrosion, even in wet, muddy, or humid conditions. This extends the life of the components and maintains smooth operation.

Complete All-In-One Kit
The kit includes everything you need for a full primary drive replacement: front and rear sprockets, the drive chain, and all mounting hardware. This eliminates the hassle of sourcing individual parts separately.

Woodniu Racein Quality Assurance
Backed by our 3-month quality promise: if you receive the kit and discover manufacturing defects (such as fit issues, chain defects, or sprocket damage), we will send a brand-new replacement free of charge (excludes man-made damage, improper installation and normal wear).
