☑ Warranty of Ebike Wheel Hub Motor Planetary Gears 36T For 250W 350W Motor

Description

This planetary gear is specifically designed for low-power rear hub motors (250W–350W) and is compatible with Bafang motors; featuring 36 teeth, it ensures efficient power transmission. Please be sure to apply an appropriate amount of grease during installation.

Please note that motors from different batches or manufacturers may feature different gear tooth profiles—specifically, either straight-cut or helical (angled) teeth.
The gear diameter and tooth profile must match your motor's specifications. To avoid purchasing the wrong part, we strongly recommend carefully checking the tooth profile and diameter of your existing gear before placing an order.
Regarding power ratings: typically, you can simply select the correct planetary gear based on the power information marked on the motor housing.
However, some e-bikes utilize power-limiting designs. For instance, a motor might be built with components rated for 500W, but the electrical system is programmed at the factory to limit the top speed to 25 km/h (15.5 mph) or the power output to ≤250W. This approach extends the motor's lifespan, improves performance, and meets the demands of frequent hill climbing.
In such cases, you should purchase a gear designed for the specific power rating, as gear diameters vary according to power output.

How can you easily select the right motor planetary gear?
Just follow these two steps:
1. Remove the old gear and observe the tooth pattern: are the teeth angled (helical) or straight (vertical)?
2. Measure the gear diameter and purchase a gear with the matching diameter.

If you still have questions about purchasing a motor planetary gear, please contact our online customer service team for assistance.
To help us answer your questions more efficiently, please provide the following information:
1. A photo of your old gear (to identify the tooth pattern)
2. A photo of the e-bike (to identify the model)
3. A photo of the code on the motor (to identify the production batch)
