Restore Crisp, Precise Shifting
E-bike motors put immense torque and stress on your drivetrain. Over time, the teeth on your rear gears will naturally wear down, leading to chain slippage, noisy pedaling, and sloppy shifting. Refresh your ride with the Official Burchda E-Bike Replacement Freewheel, engineered to handle high power output and restore your drivetrain to factory-fresh performance.
Key Performance Features:
E-Bike Specific Durability: Constructed from high-tensile hardened steel to withstand the extreme torque generated by powerful electric hub motors.
Smooth Gear Transitions: Precision-cut gear teeth ensure fluid, accurate, and crisp shifting across all gears, whether you are climbing steep hills or cruising on flat roads.
Corrosion Resistant: Finished with a rust-resistant coating to extend the lifespan of your drivetrain, even in harsh weather conditions.
🛠️ Fitment Guide (How to Order Correctly):
To ensure perfect compatibility with your specific Burchda e-bike and derailleur system, please follow these two steps before adding to your cart:
Select Your Bike Model: Choose your exact e-bike frame (RX80, R5 Pro, U8, HC26, Y3, C35, or RX30) from the first dropdown menu.
Select Your Speed (Crucial): Burchda e-bikes come with different gearing options. Please count the number of gears (cogs) on your current rear wheel or check your handlebar shifter.
If you have 6 gears, select 6-Speed.
If you have 7 gears, select 7-Speed.
If you have 8 gears, select 8-Speed.
