What is a star ratchet hub?

A star ratchet hub is a robust and reliable hub design which distributes the load of your eBike’s motor across 36 points-of-contact opposed to the 4-6 points-of-contact on a pawl based hub.

This addresses a common point of failure for many regular hubs where the pawls will break or strip the race in the hub causing the power to no longer be transferred to the rear wheel. The even distribution of power between the star ratchet teeth ensures a smooth and reliable drivetrain.

No Tool Construction

The star ratchet hub can be assembled and disassembled with no tools, resulting in easy access to bearings, freehub body replacements,  and configuration between 190m and 197mm.
