### ⭐⭐⭐⭐⭐ Works perfect!
*by L***. on August 26, 2024*

I cut a keyway in mine for the application and it turned out perfect. In my view this is the best way to mount the sprocket on a motorized bicycle . I may need to buy another . Thank you very much . Larry k.

### ⭐⭐⭐⭐⭐ Get this!
*by C***S on April 30, 2023*

This is better in every way possible, it's easy to install, fits on most if all modern hubs, it's cheap but not cheaply made. I could go on but one thing to know keep the bolts tight.
