Bixpy SUP Fin Box Adapter

This is the part that turns a paddleboard into a motorized paddleboard: a fin-shaped adapter that fits your board's existing fin box, with Bixpy's standard attachment interface on the trailing edge. Your K-1 (or previous-generation J-2) motor clicks on and off in seconds — the adapter stays put and even works as a regular fin when the motor's at home.

Which one fits your board? Match the adapter to your fin box, not your board brand:

• US Fin Box — the long screw-and-plate center fin box found on most rigid boards and many inflatables.
• Slide & Lock — tool-less slide-in boxes with a locking tab, common on inflatables.
• Flip & Lock — tool-less boxes with a flip lever or clip pin, also common on inflatables.
• All 3 Fins Bundle — every adapter in one box, for households with a fleet or boards that change.

If you're not sure which box your board has, check the fin that came with it, look up your model in Bixpy's finder at bixpy.com/bixpyymm, or send us a photo — we'll tell you. Board has no fin box at all? You want the DIY Fin Box Adapter instead.
