About Samox

Samox is a specialist manufacturer of eBike drivetrain components, producing chainrings and motor sprockets engineered to meet the unique demands of electric bicycle systems. With eBike motors generating significantly higher torque than a standard pedalling input, drivetrain components need to be built to a higher standard — and that's exactly what Samox delivers. At Swinnerton Cycles, we stock Samox components for eBike owners and workshop mechanics looking for quality replacement and upgrade parts.

Engineered for eBike Torque

Standard chainrings are not designed to handle the sustained high-torque output of an electric motor. Samox eBike chainrings are manufactured from hardened steel or reinforced alloy, with tooth profiles optimised for the chain loads generated by mid-drive motor systems. The result is a component that lasts significantly longer than a standard chainring under eBike use.

Bosch & Multi-Platform Compatibility

Samox produces motor sprockets and chainrings compatible with Bosch Performance Line, Bosch Active Line, Shimano Steps, and other leading mid-drive motor platforms. Direct mount options simplify installation and reduce the number of components required, while steel construction ensures durability across a wide range of riding conditions.

Choosing the Right Samox Chainring

The correct chainring depends on your motor platform, the mounting interface on your motor unit, and your preferred tooth count for gearing. Tooth count affects your overall gear ratio — a smaller chainring gives easier climbing, while a larger ring increases top-end speed. If you're unsure which Samox part is compatible with your eBike, the Swinnerton Cycles team can help you identify the correct specification.
