Compatible With
- Assist Slim
The Foil Drive Assist Slim is built for riders who want maximum performance in the smallest, lightest package. Designed for advanced surfers, downwinders, and wing foilers, this kit delivers just enough electric assist to get you on foil sooner, ride smaller boards, and push your progression further.
Foiling here is all about versatility - from Orewa’s clean lines to wild downwind runs along the coast. The Assist Slim makes it easier to catch waves, link bumps, and push progression without the bulk of larger systems. It’s a pure performance upgrade, not a crutch.
Why Choose the Assist Slim in NZ?
- Advanced riders chasing a low-profile, lightweight feel
- Downwinders & wingers who don’t need long run times but value efficiency and freedom
- Surfers looking for just enough boost to pop up on foil and enjoy smaller, more agile setups
At Underground Surf, we’ll help you choose the right setup for your riding style and conditions. That means you’ll get expert advice from real foilers, fast NZ-wide shipping, and the chance to demo and learn before you commit.
