Buying Guide
Planetary gears make your e-bike ride smooth and strong. They help your motor work better and last longer.
I once swapped out a worn gear set with a new 36T steel clutch kit. The change was instant—less noise, better control, and a ride that felt brand new.
-
Material: Choose nylon for quiet rides and steel for strength. Nylon is light and soft, while steel lasts longer under heavy use.
-
Teeth Count (T): Most e-bike gears use 36 teeth. More teeth mean smoother power, but fewer teeth can give quicker response.
-
Gear Diameter: Match the diameter to your motor. Common sizes are 38mm and 47.5mm. A wrong size won’t fit or may cause damage.
-
Clutch Compatibility: Some kits include a clutch for better control. Make sure the clutch size, like 88mm, fits your motor.
-
Motor Power Match: Check if the gear fits your motor’s wattage. Many gears work with 500W to 750W motors. Using the wrong gear can reduce performance.
-
Bearing Fit: A good gear has a bearing that fits well, often 8mm. Bearings reduce noise and help the gear spin smoothly.
-
Ease of Installation: Look for gears that are easy to install. Kits with clear sizes and smooth edges save time and effort.
-
Durability: Pick gears made with high-quality materials. Strong gears resist wear and keep your bike running longer.
-
Noise Level: Nylon gears are quieter than metal ones. If you want a silent ride, go for nylon with good bearings.
-
Weight and Size: Smaller gears like 3.8×1.3cm are light and easy to carry. They’re great for quick fixes or travel spares.
-
Design Shape: Some gears have a spur shape. This helps with clean rotation and easy fitting.
Choose wisely, and your e-bike will thank you with every smooth ride.
