I’ve had this jtfrkope 3 Pulley Chain Tensioner Roller on my wishlist for a while, especially since I’ve been tinkering with my motorized bicycle setup. When it finally arrived, I was immediately curious about how well it would hold up under real riding conditions.

The first thing I noticed is its lightweight design—just 180 grams—but it feels sturdy enough to handle the vibrations of a 2-stroke engine. The package includes three rollers, which is great because you never know when one might wear out or get damaged.

Installing the tensioners was straightforward, thanks to their decent size compatibility with various engine sizes (49cc to 100cc). I checked my bike’s original parts first, and it matched perfectly, so no surprises there.
