KMC (Kuei Meng) International Inc.
e-Bike Solution, with its unique “Chain Mate” design for superior chain and cog tooth running efficiency and specially designed teeth for enhanced chain retention, the chainring roller seats between teeth are perfectly matched to chain rollers for exceptional component engagement. Benefits of this include unparalleled power transmission efficiency and longer component lifespan. “Shield Tech” is a patented new riveting tech that utilizes a reinforced pin design: the pin surface is raised 10% and significantly increases 25% of pin power.
In addition to “Chain Mate”, e-Bike Solution offers chain retention, which is enhanced via an optimized tooth design to hold the rollers in place, significantly preventing chain drop while also reducing friction associated with traditional narrow/wide designs. The tooth design is vertically asymmetrical to avoid interference while at extreme chain angles to the rear cassette.
With the diverse use of e-Cargo bikes, KMC has designed a chain with a focus on strength and long life. Unparalleled tensile strength and outstanding durability surpass all expectations of a dedicated e-Cargo chain. In response to significantly increased force on e-Cargo drivetrains, the e-Cargo chain exceeds international tensile-strength standards to achieve a market-leading 1350kgf, which is 30% higher than other KMC e-Bike chains and 50% higher than industry standards.
Redesigned protective bushings cover pins to reduce abrasion and high-load wear, allowing eCargo1 chains to last over twice as long as usual. Unique “O-Shaped” inner and outer plates have been strengthened by 13% and 20%, respectively. Wider and thicker plates allow for increased strength, stability, and provide anti-chain drop assurance.
