Product Details
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.
- LHLorne H.Verified BuyerRated 4 out of 5 stars4 years agoGood Quality Pricey Shipping
The quality of the Bosch parts I ordered is definitely decent. I ordered a lock ring and 2 rubber seals and the shipping was as much as the parts. Id like to see Scooteretti provide more inexpensive options. A padded envelope through regular post would have been fine and much cheaper.
SScooteretti4 years agoThank you for your feedback and most importantly your purchase with us. While we understand that shipping costs can be quite high on small items like these we simply had too many complaints from customers with Canada Post. We do offer FREE shipping on purchases over $150.00 in case you need to stock up on some tires, tubes, lube etc... in the future.
