BBB Cycling E-Bike Sprocket BCR-70E, 14T

The BBB Cycling E-Bike Sprocket BCR-70E is a single 14-tooth drive sprocket for compatible Bosch mid-motor systems. It is made from hardened steel and is offered with a retaining lockring. The marked sides identify mounting positions for different chainlines, making orientation an important part of selection and fitting. The motor interface, chainline and existing chain must match this particular version.

Version and details

• BBB BCR-70E with 14 teeth.
• Hardened steel.
• 3/32-inch version for compatible Bosch systems.
• Side markings for 135/142 mm and Boost 148 mm arrangements.

Selection and use

Compare the sprocket designation, interface and chain width with the existing part. If uncertain, ask a workshop to identify the Bosch motor generation and chainline. Follow the side marking and the drive manufacturer’s specified fitting values. The Bosch brand name alone does not establish suitability for every system.

Care and inspection

Check the teeth, chain and attachment for wear, damage and unusual play. Clean the drivetrain with suitable products and follow the bicycle’s service instructions. After fitting, confirm secure attachment and smooth chain movement before riding under load.
