Overview
Upgrade your eBike’s drive system with a star ratchet hub manufactured by Wren Sports. Designed to excel in high-torque situations with powerful mid-drive motor eBikes. Available in 32 hole and 36 hole variants and can be set up for 190mm or 197mm rear-ends.
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.

LX was shreading hubs. 3 bearing failures in original and 2 replacement hubs. LX’s 160Nm Mid Drive motor was too much for cheap Chinese hub to handle. Ratchet hub solved that problem. Got my bike back again!!!
