The Assist Slim is smaller and lighter with a shorter run time, designed for performance foiling. It offers enough power for assisted foiling, while remaining super compact!
At just 35mm thin, the Foil Drive Assist Slim is specifically engineered for performance-oriented riders looking for assisted power only. Whether you’re carving sharp turns on a prone board, tackling downwind missions in challenging conditions, optimizing smaller gear for wing foiling, or extending your pump foil sessions, the Assist Slim delivers exceptional performance.
While it features a reduced battery capacity that results in shorter runtimes, the Assist Slim still packs a powerful punch for assisted popups. With its low weight strategically positioned under your board, you'll hardly notice it’s mounted - once you’re up on foil, it feels like pure freedom!
Note: The Assist Slim is designed for assisted foiling only and is intended for use to "pop up" on foil then ride unpowered.

The Assist Slim mounts between your mast plate and the board. As mast tracks are universal, this means it fits any board! Simply use the provided Foil Drive Locking T Nuts and longer bolts. Sandwich your Gen2 Foil Drive between your gear for optimal weight distribution and hydrodynamics.
Note: Boards with Carbon Tracks may require an additional External Antenna.
Removable Motors
With three simple screws, the motor plug can be removed, allowing the rider to change their motor height through swapping between different cable lengths.
With options to use your own foil mast or a fully integrated option, there are more ways to tune your setup than ever!
