Wheels Manufacturing E-bike Lockring Socket

This socket is specifically designed for use with Bafang mid-drive systems that utilize the M33 outer lockring. It is not a universal tool, so please verify your motor model before purchasing.

The socket features a standard 1/2-inch square drive, meaning it is compatible with most standard ratchets, torque wrenches, or breaker bars found in a typical home or professional bike shop.

Yes, it is precision-machined from high-quality aluminum and anodized for extra durability. While it is robust enough for regular maintenance, it is always best practice to ensure the tool is fully seated on the lockring before applying torque to prevent slipping.

Yes, Wheels Manufacturing includes a 1-year warranty against manufacturing defects, covering you in the event of any material or production issues.

We strongly recommend using a hand-operated ratchet or torque wrench. Impact wrenches can generate excessive force that may damage the aluminum socket or the lockring itself.
