If you’re a product nerd, it has been an exciting time when it comes to hubs. As of late, we got a look at the long awaited Flybikes Magneto Cassette Hub and the new Eclat Seismic Hub that are making some big changes to the way cassette hubs work, now it looks like the Freenight Planetary Coaster Hub that has been in the works for quite some time now is available. This one is unique because it’s basically a freecoaster and a cassette hub in one utilizing a system that’s been used before, but modified to make it work much better. Here is a short video Night Rider BMX Shop put together giving you a look at the driver internals and just how it all works. After you check out the video, you can learn more about the hub over on the Freenight Website where they have photos, specs and details on the hub for you to get a look at.

This new and innovative hub allows you to enjoy a Cassette feeling while riding forward, and Freecoaster slack moving backwards.
Hi, and welcome to the inside of the freenight hub.
The freenight hub is a planetary coaster. To understand what it means, I’ll start by explaining the basic idea.
Let’s begin with the driver. Each pawl is kept down by a spring, and the driver engages when the pawls are lifted by a clutch disc. If you know your history, you might have seen this before. That idea was very nice and simple, but it had one major trouble – there was no control over the clutch disc.
This is where the planetary clutch comes to work.On the side that faces the driver, there is a clutch disc with ramps for each pawl. When moving forward, the ramps are always close to the pawls, so we get immediate engagement. Moving backwards, the ramps are always far away from the pawls, so it prevents unwanted engagement. In other words – moving forward you have minimal slack, and moving backwards you have maximum slack, it’s that simple.
There will be more videos explaining the inside of the clutch itself, and also tutorials for hub assembly, all coming soon.
