If you have ever had to push your Light Bee because of a belt rupture, you're probably in the right place!

The Chain Kit replaces the belt and pulleys by a chain drive and two sprockets. It brings a huge improvement in two ways:

  • it is way more robust than a belt, especially in sandy or muddy conditions,
  • it is more efficient than a belt as it has a smaller contact surface and a lower coeficient of friction.

The Sur Ron Light Bee Primary Chain Kit is composed hardened steel 13T motor sprocket and 30T reduction shaft sprocket with a precut DID chain. The 13T/30T combination preserves the original gear ratio.

In addition, changing a chain is way easier than a belt replacement as there is no need to remove the swingarm.

Absolutely Flawless!

I was looking for reliability after upgrading to 72v, having blown my belt. Not only is it stronger, but I've gained responsiveness! Easy installation, no complaints! Just a little grease after each ride and it's perfect! (Love the sound 😍)

Thanks for the feedback! I totally agree about the noise – some see it as a downside, but personally, I love it! My bike sounds even more powerful 🚀

More Reliable Than the Belt!

A little more noise (a whistle), but *much* more reliable for use in rivers, dirt, and sand. Installation is straightforward.

Great Product, But Consider the Noise!

A really good product as such, no complaints. However, for my use case (especially in the city or in the forest in stealth mode) it's really too loud. I definitely underestimated the reviews found online about this. Don't make the same mistake. I'm keeping it just in case, but the belt is better for urban/light enduro use.

Finally, No More Belt!

Fits perfectly, plug and play. A little noisy at first, but once broken in, it gets much better, and it helps you be a little more heard!!!
