FYI, seems helix is finally getting ready to launch the electric model, after many delays. They shared a bideo on their instagram and facebook accounts (I'm not allowed to share links yet).

The "bottle" in the video appears to be some variant of an HZPT battery, and you can see a wire coming out of it.

I emailed helix, and they basically confirmed it. They also said it will be backwards compatible with existing Helixes.

Alongside the new racks and fenders, glad to see things seem to be picking up a bit for Helix
