Why Nylon for E-Bike Motor Gears?
80% quieter than steel gears during operation
Acts as sacrificial component to prevent expensive motor damage
Reduces maintenance and extends component life
Lower rotating mass improves efficiency and range

Installation & Maintenance
Installation Time: 1-2 hours (requires motor disassembly)
Tools needed: Allen keys, screwdrivers, grease
Extend Gear Lifespan - Follow These Tips:
- β Shift before power: Always change gears BEFORE engaging motor to avoid high-torque starts
- β Monitor temperature: Avoid prolonged climbs at maximum power (overheating weakens nylon)
- β Proper lubrication: Use high-temperature grease during installation
- β Correct chainring size: Smaller chainrings (42T-44T) reduce gear stress vs. larger rings (52T+)
- β Avoid water crossings: Minimize deep water exposure to prevent premature wear

Common Questions
How do I verify compatibility with my motor?
Step 1: Check the model marking stamped on your motor casing
- If it says "BBS01B" or "BBS02B" β Select BBS01B-BBS02B variant
- If it says "BBS03" or "BBSHD" β Select BBS03-BBSHD variant
- If it says "BBS01" or "BBS02" (no "B") β These gears won't fit, contact us
Step 2: Still unsure? Email a photo of your motor markings to beeplastic@beeplastic.com
What's the difference between PA6 and PA66 nylon?
PA66: Higher heat resistance (up to 110Β°C), better for high-power motors (BBSHD 1000W+)
PA6: More cost-effective, sufficient for standard motors (BBS01B/BBS02B 250W-750W)
We select the appropriate grade based on your motor model. Contact us for specific material requests.
