Bosch Lock Ring Seal / O-Ring – For Bosch eBike Systems
Maintain optimal performance and secure chainring installation on your Bosch-powered eBike with the Bosch Lock Ring O-Ring. This essential component ensures a proper seal between the Bosch lockring and motor interface, preventing unwanted movement and protecting against dirt and moisture ingress.
Why replace it?
Every time the aluminium lockring is removed or reinstalled, the O-ring should be replaced. Over time, used O-rings become compressed, lose their original shape, and may no longer provide a tight, secure fit. A fresh Bosch O-ring ensures your drivetrain remains solid, sealed, and reliable.
Key Features:
- Critical Seal Integrity: Provides a snug fit between the lockring and motor, reducing the risk of drivetrain looseness or vibration.
- Prevents Wear & Contamination: Helps protect internal components from dirt, water, and debris.
- Replace Every Time: Always install a new O-ring when the lockring is removed or re-torqued to maintain optimal sealing and drivetrain performance.
- Genuine Bosch Part: Manufactured to exact Bosch specifications for a perfect fit and long-lasting durability.
Fitment Tip:
To ensure you choose the correct O-ring for your Bosch motor, please refer to the chart below and match the O-ring to the lockring part number or motor generation on your eBike.
Compatibility:
- Designed for all Bosch ebike drive units
- Specific sizing required, refer to the guide below to confirm correct fitment
Keep your Bosch eBike performing at its best with a fresh lockring O-ring—small part, big impact.
