Comprehensive Review: Alomejor 36T Nylon Gears and 88mm Clutch Kit for Bafang Mid-Drive Motors
The Alomejor 36T Nylon Gears and 88mm Clutch Kit represents a critical upgrade or replacement component for owners of Bafang mid-drive electric bicycle motors, particularly those in the 500W–750W range. Designed as a robust spare part for motor transmission systems, this kit combines durable materials and precision engineering to address common wear-and-tear issues in high-torque e-bike applications. Below, we delve into its technical specifications, user experiences, and compatibility considerations to evaluate its performance and value for cycling enthusiasts.
Technical Specifications and Design Features
The Alomejor kit comprises two primary components: a set of 36-tooth (36T) nylon gears and an 88mm steel clutch assembly. Both parts are engineered to replace factory-installed components in Bafang motors, which are widely used in mid-drive e-bike systems.
-
Material Composition
- Nylon Gears: The 36T gears are crafted from high-strength nylon, a material chosen for its balance of durability, lightweight properties, and resistance to wear under high-stress conditions. Nylon’s inherent shock-absorbing qualities reduce noise and vibration during operation, a feature particularly beneficial for urban commuters or off-road riders.
- Clutch Assembly: The 88mm clutch is constructed from alloy steel, ensuring rigidity and longevity. Steel’s resistance to deformation under load makes it ideal for clutch mechanisms, which must engage and disengage smoothly under varying torque demands.
-
Bearing Integration
Each nylon gear is pre-fitted with DVOT 608Z bearings, a standard in e-bike motor systems. These bearings facilitate smooth rotational motion while minimising friction, a critical factor in maintaining motor efficiency over extended periods. -
Compatibility
The kit is explicitly designed for Bafang mid-drive motors, including models such as the BBS01, BBS02, and BBSHD series. While marketed for 500W–750W systems, anecdotal feedback suggests compatibility with higher-powered 1000W motors, provided the clutch mechanism’s torque tolerance aligns with the motor’s output.
Performance and User Feedback
The kit has garnered praise for its ease of installation and reliable performance, particularly among riders seeking to revitalise aging motors or upgrade stock components.
- Seamless Fitment: Users highlight the kit’s precise tolerances, which allow for straightforward retrofitting into existing motor housings. One reviewer noted that the gears “slotted into place without modification,” emphasising the product’s adherence to Bafang’s original design specifications.
- Enhanced Durability: The nylon gears’ resistance to wear has been a recurring theme in feedback. Riders report significant reductions in gear chatter and meshing noise compared to OEM plastic components, attributing this to the nylon’s superior damping properties. The steel clutch, meanwhile, is lauded for its “solid engagement” under load, eliminating slippage during aggressive acceleration or hill climbs.
- Smooth Operation: The inclusion of DVOT 608Z bearings contributes to a noticeable improvement in drivetrain smoothness. A tester remarked on the “buttery rotation” of the gears, even after prolonged use in wet conditions, underscoring the bearings’ corrosion resistance and lubricant retention.
Use Case Scenarios
This kit is particularly advantageous for:
- Preventive Maintenance: Replacing factory gears before failure occurs can prevent costly motor damage. The nylon gears’ resilience to chipping or tooth deformation makes them a prudent upgrade for high-mileage riders.
- Performance Upgrades: Riders seeking to optimise torque delivery or reduce drivetrain noise will find value in the steel clutch’s robust engagement and the nylon gears’ vibration-dampening properties.
- Motor Revitalisation: For older Bafang motors exhibiting gear wear or clutch slippage, this kit offers a cost-effective alternative to full motor replacement.
Installation Considerations
While the Alomejor kit is designed for DIY installation, users should note the following:
- Tool Requirements: Circlip pliers are necessary for removing and reinstalling the clutch assembly.
- Lubrication: Applying a high-viscosity grease to the gears and bearings during installation is recommended to prolong service life.
- Compatibility Verification: Although the kit is broadly compatible with Bafang mid-drive systems, cross-referencing motor model numbers with manufacturer guidelines is advised.
Conclusion
The Alomejor 36T Nylon Gears and 88mm Clutch Kit stands out as a reliable, well-engineered solution for Bafang mid-drive motor maintenance and enhancement. Its combination of high-strength nylon, alloy steel construction, and precision bearings addresses common pain points in e-bike drivetrains, offering riders improved durability, smoother operation, and reduced maintenance intervals. While primarily intended for 500W–750W motors, its adaptability to higher-power systems further broadens its appeal.
For cyclists prioritising longevity and performance in their electric-assist systems, this kit represents a pragmatic investment. Its design fidelity to Bafang’s original components ensures minimal downtime during installation, making it a worthy addition to any e-bike enthusiast’s toolkit.
