Heavy-Duty E-Bike Crankset Replacement

Optimized Power Transfer & Everyday Reliability

The crankset is the heart of your e-bike's pedaling system. Whether you are replacing a worn-out component or repairing impact damage, the Official Burchda Heavy-Duty Crankset is engineered to withstand the high torque of electric riding while keeping your daily commute smooth and clean.

Key Performance Features:

• Heavy-Duty Alloy Construction: Forged from high-strength, lightweight aluminum alloy. It provides maximum rigidity for efficient power transfer without adding unnecessary weight to your ride.

• Integrated Dual Chain Guard: Features a premium double-sided alloy cover. This crucial design prevents your chain from derailing on bumpy terrain and keeps your pants safe from getting caught or stained with chain grease—perfect for daily commuting and casual riding.

• Smooth & Efficient Pedaling: Precisely machined chainring teeth ensure seamless engagement with your e-bike chain, reducing drivetrain noise and improving overall shifting performance.

⚠️ Fitment Guide (Choose Your Model):

Because different Burchda e-bikes utilize specific bottom bracket widths and frame geometries, these cranksets are model-specific and not universally interchangeable.

To ensure a perfect, friction-free installation, please select your exact e-bike model (Y3, HC26, R5 PRO, RX30, RX80, or U8) from the dropdown menu above before adding to cart.

(Pro Tip: When replacing your crankset, we recommend inspecting your pedals and bottom bracket for any wear or bearing play to ensure a completely refreshed drivetrain.)
