I recently bought the DJI OSMO ACTION 4 Adventure Combo. It came with extra battery and a selfie stick. Check Amazon for full specs and bundle.
I am not using any ND filter yet so I had to shoot this on full auto. ND filter would give me more control on choosing a desired frame rat.
The morning ride had audio captured separately. The night ride with the Action 4 inbuilt mic and I am happy with the wind noise reduction.
