Clicking noise

[ptizio]

My bikes making this clicking noise that's really subtle but it sounds like it's coming from inside the cassette or inside wheel area. Any idea what this may be? I know it's a vague question but it's really hard to tell/explain where it's coming from. I have a video of it if it helps. Thanks

does it click when you are pedaling, or just when coasting?

When coasting is normal, it is the pawls clicking inside the freehub/freewheel. The pawls engage when you pedal, but move to allow coasting without the pedals going around.
