Saw this clever idea on the Foil Drive Owners group and really liked it, so sharing it here in case someone wants to design or refine it.

The original poster had a video, but it was removed, so here’s my best attempt to describe the mechanism:

  1. Mast wrapper
    The wrapper is open on the left side, allowing it to slide onto the mast.

  2. Locking column pin
    A vertical pin is inserted into a channel on the left side of the mast, which locks the wrapper in place and prevents it from opening.

  3. Motor base
    The motor has a dedicated base that serves two purposes:

  • It seats securely inside the wrapper.

  • A bolt runs through the motor and fastens the base either to the wrapper or to the column pin, creating a solid connection.

Any idea how they prevent this thing from riding down the mast over time?

It is one of the bit annoying sides of my strap mounted pod, how it slowly wiggles down the mast over time.

if you are pumping a lot that is.
Not sure that is an issue otherwise.

Also one of the reason I went for the pod on the controller plate and not on the mast. It would pull the wires and end up unplugging my motor in my v2 assist.

Pod looks nice, but I did not fully understand the working peinciple

If it slides, it is really bad. Does it happen with TPU insert and with TPU strap as well? TPU supposed to inhibit sliding…

Another problem I discovered with the nano pod is that is can pushed/rotated vertically.

Wrapping the cable and pod cable extension together with the mast supposedly tackles both problems.

  1. Imagine sliding bolt through motor stator and through the back bearing and then screwing it into the mast wrapper.
    But now in between the motor and wrapper there is a part attached to motor with the m4 screws. The screw clamps that part to the wrapper thus attaching motor to the wrapper.
  2. The wrapper is open on the left but the edges are twisted, such that inserting an appropriate pin will tension the wrapper on the mast.

Ah the good old foil drive behaviour where if you show a better product than what they have theyll delete it because they really dont like competition in there…
