The Assist Slim base kit comes without a motor or battery, letting you build your system exactly how you want it.
The Assist Slim is the lightest model in the Foil Drive range. It keeps that weightless feel and natural foil behavior, while still delivering enough thrust to get you flying. This base kit is for riders who are installing an integrated mast, already own Slim batteries and motors, or prefer to build their setup piece by piece.
Why choose a base kit?
There are three main reasons. Maybe you're buying an integrated mast that already includes its motor, and you don't want to pay for a second one. Perhaps you're setting up a second board and already have Slim batteries and motors. Or you simply prefer to choose each element yourself rather than grabbing a ready-made kit.
The Assist Slim's character
The Slim focuses on responsiveness, agility, and minimal drag. It delivers short, powerful bursts to get you up on the foil, then it gets out of the way for pure glide. You get the same peak power as the Assist MAX, but in a thinner, more compact housing. This is the choice for experienced riders who want balance and a super light weight, whether they're riding in Surf, wake, windswell, or flat water.
What you need to add
You'll need a v2 motor (standard or high power) and a Slim battery. The housing accepts the Slim Performance in a dual configuration, the Slim Endurance, or the Slim Travel. Choose the cable length based on your mast height; you can always change it later with the removable motor cable.
What's included and what's not
Included: the Assist Slim electronic housing, the universal mast adapter (compatible with almost all masts on the market), Bluetooth connection to the Foil Drive app, and the transport bag.
Not included: the v2 motor, the battery, the charger, and the three-blade conversion propeller.
In short
