What we think:

Finding new ways to get on foil! Foiling has certainly swept the industry whether it be with a kite, a wing, a wave, a dock or a wake. Im going to be honest, when I first saw the original Foil Drive, I thought it was a good idea but a little clunky and home made looking. Tons of customers were loving them though. When this happens I know its time to listen and investigate further into a product. While I was looking to bring the Assist Plus into the shop, I found out about this new and very exciting Gen2 system that was to release soon. What excited me the most is the fact there is NOTHING on top of the board! The battery and system itself is all packed nicely right under the mast. I was instantly way more interested.
We received a demo unit of both the Max and the Slim. So I took them to a flat water spot first to give them a test. Man…i am impressed. All I can say is; “Game Changer”.  Personally I have now had about 4 sessions on the Slim in the waves after the first flat water test. I probably would not have been able to catch any waves without this thing on most of those days.
I think the SLIM is perfect for me since I want performance and am decent a pumping. The MAX seems to be the favorite for anyone who is not more advanced or wants longer sessions. I’ve been using the 20cm cable length which I think is a pretty good “go-to”. However, i’d love to try a 15cm for even more performance and extra room to pump on the mast. There is a slight adjustment period on figuring out how to pop up and get the prop out of the water. But it didn’t take me long to dial it in. Due to the light weight design and placement, you really do not feel much of any swing weight while pumping this thing. I was easily connecting 4-6 waves on 880cm^2 front wing and my 37 liter board.
We have been taking orders for these and the demand has been way better than expected. Our first order batch sold out almost instantly for the Max. If you have an interest, I’d suggest you get your order in NOW! The longer you wait to get the order in, the longer you will wait to get your unit! Dealers are getting priority over direct orders from Foil Drive themselves. -Billy”

Gen2 takes everything Foildrivers have come to love and has been enhanced dramatically. Everything from the fit and finish, to the capabilities and features, Gen2 is an all rounder. Mounted between the board and the mast, the Assist MAX diversify the range and are a step up in the world of hybrid foiling.

The Assist MAX is exactly that, an all rounder with maximum power, runtime, thrust and versitility. This is the largest Foil Drive suitable for any rider at any skill level!

*Max Thrust: 27.5kg (60.6lbs)

*Weight Range: 3.4 – 4.5kg (7.4 – 9.9lbs)

Max Dimensions: L525 x W250 x H50mm

Min Dimensions: L415 x W250 x H50mm

* Dimension/weight variations based on different batteries. Max Thurst based on Three Blade Propeller, data will vary based on real world, rider variables (Full real world thrust analysis available online). GEN2

Gen2 utilizes the same robust motor, propellers and mast adaptor as Gen1 with changes to the system modularity. A custom water resistant motor plug seamlessly connects the electronics box to the motor allowing rider to interchange between a range of different cable lengths. By simply removing 3 bolts and plugging in a new motor, the rider can now have a quiver of motors for different foiling disciplines or preferences.

Who rides the MAX?

It doesn’t matter if your surfing, down winding, Winging or in flat Water, the Assist Max is for everyone, however heavier riders and those wanting to just pull the trigger ang fly will love the extra run time and thrust.

If you’ve been around Foil Drive before, the Assist MAX is for anyone who loves the runtime of the Assist PLUS and is keen on more power and more runtime! If you’re new to Foil Drive, the MAX is the perfect all rounder!

Install on any Foil Board & Mast

Gen2 Foil Drive Systems mount between your mast plate and the board. As foil mast tracks are universal, this means it fit’s any board! Simply use the provided locking T nuts and longer mast bolts. Sandwich your Gen2 Foil Drive between your gear for optimal weight distribution and a clean top board surface.


Each of their Assist Kits are compatible with their own Foil Drive batteries that offer different benefits for different use cases, runtime, power, weight and compatibility are all key variables. The Lithium-Ion Battery Cells used in the Foil Drive systems feature the highest energy density available while maximizing the power output, run time and performance of the system. This means they really are packing as much as we can into such a small space!

Gen 2 Motor Systems

Gen2 Motor Systems are available in 5 different lengths that are interchangeable.The length being the distance between the base plate and the motor position on your mast. These lengths are shorter than Gen1 as the cable does need have to wrap around to the top side of the board. Each position has been curated for specific use:

  • 15cm/5.9inches We often refer to this position as slammed as it’s as close to the board as possible without noticing interferance due to it’s proximity to the board. The ideal for those wanting assistance to get on foil, and have their motor exit as soon as they’re on foil.
  • 20cm/7.8IN A step down from the slammed position, this is most common for most riders wanting assisted power in most disciplines. The motor remains in the water a little longer meaning you can really rely on it to get you up and running.
  • 25cm/9.8IN Wanting to flatwater Foildrive back to the lineup? Learning to surf, downwind or wing? The mid mast position gives you enough depth to motor around but remains high enough to pop the motor out of the water once you’re up on foil and feeling ready to glide naturally.
  • 60 & 70cm 23.6 &27.5IN Positions close to the fuselage are ideal for flatwater Foildriving and learning. A 60cm and 70cm Motor are available with the same use case. The 60cm Motor is suitable for masts up to 60cm long, where as the 70cm Motor is for masts longer than 70cm.



Are batteries cross-compatible?

Foil Drive batteries are NOT cross compatible across units ie. An Assist battery cannot be used in an Assist PLUS.

What is the lifespan of a battery?

All batteries have a useful lifespan and are consumables. Due to battery chemistry, every time a battery is used it will slowly degrade and the loss of full power output and capacity will eventually become noticeable. Depending on how often it is used, 1-2 years of good performance is typical when cared for correctly.

Are they waterproof?

Foil Drive batteries are not waterproof and should be treated with care, especially around salt water. Please contant Foil Drive if your battery is ever exposed to water. Gen1 Batteries have been designed to limit water ingress if they do become exposed to water however are more suspeciable to damage. Gen2 Batteries are custom made with massive advancement in durability and safety. They have been IP68 certified for dust and water resistance.

How much runtime?

Battery runtime is a very hard number to give a single answer to. Foiling is an incredibly dynamic and complex sport, making it impossible to have fixed values. While we do provide average runtime, we believe in honest, real world examples. Available online is an extensive look into each battery, comparing rider weight, gear and more in order to give you the best idea of how much you can get out of each battery depending on your specific use case.
