Sunlite e11 E-Bike Chain — Single Speed, 128 Links, Diamond Hard Coated, Silver

The Sunlite e11 is a single-speed chain built specifically for e-bike use, where constant torque and higher loads quickly wear out standard chains. It uses a Diamond Hard surface coating to slow wear and increase surface hardness, making it a solid replacement option for e-bikes running single-speed drivetrains.

This chain is intended for utility, commuter, and cargo-style e-bikes where durability and quiet operation matter more than weight savings.

Key Features
• Single-speed chain designed for e-bike torque loads
• Diamond Hard Coating to reduce wear and extend chain life
• Deep inner waist chamfer for quieter, smoother operation
• Sub-punched pins for increased tensile strength
• Silver finish
• 128 links (long length for e-bike chainlines and chain cases)
• Chain size: 1/2" × 3/32"

Compatibility & Use Notes
• Designed for single-speed e-bike drivetrains
• Compatible with standard 3/32" single-speed chainrings and cogs
• Not compatible with multi-speed derailleur systems
• Suitable for hub-drive and mid-drive e-bikes running single speed
• Requires proper sizing during installation

Service / Ownership Context
Single-speed e-bike chains see continuous load and wear faster than pedal-only chains. The e11 holds up better than standard BMX or utility chains, but regular wear checks are still important to protect chainrings and rear cogs. Extra length allows proper sizing on bikes with long chainstays or chain guards.
