The Kewig X4-B3 magnetic mount holds a DJI Osmo Action 3, Action 4, Action 5 Pro or Osmo 360 and has a sliding anti-drop lock. The base is a 1-inch ball that goes into a joint arm on the bike. Price 465,000 VND.
One camera, two mounts
When the same DJI camera goes on the helmet and on the bike, you pick the mount to suit. The 1-inch ball base goes into a joint arm on the bike. BigBike has test-fitted the DJI Osmo Action 3, Action 4, Action 5 Pro and Osmo 360, and all four fit. The Kewig X1 takes the same four cameras but has a two-prong GoPro-style base for the helmet and no lock. The Action 6 does not fit this mount, see the Kewig X4-B6.
The sliding lock
Before riding into the mountains up north, seat the camera in the mount. The magnet guides the camera into position, the two side latches hold it, and the sliding lever locks those latches. Once slid to lock, the side latches cannot be pressed. If you forget to slide it, only the two side latches hold the camera.
Fitting the camera
A Kewig C2U2, Kewig C9P or Kewig R8A ball base connects through a Kewig J1S joint arm to the mount. The box holds exactly one mount; the other two parts are bought separately. Take the camera off once you have stopped at a coffee shop.
Seat the camera → Slide the lever to lock → Stop, slide to open → Press both side latches → Lift the camera off.
The sliding lock stops the two holding latches from being pressed open.
The camera comes off by sliding to open, pressing both latches and lifting.
Aluminium alloy mount, 62 g.
Does not take the DJI Osmo Action 6; that model needs a different mount.
The mount needs a joint arm and a ball base; it does not attach to the bike by itself.
Until the lever is slid to lock, only the two side latches hold the camera.
BigBike makes no promise on a specific load or riding speed for this mount.
