What we think:
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 MAX is best suited for riders under 100 kg using small to midlength boards and their preferred foil setups, offering a single system that performs across surf, wing, downwind, wake, flatwater, and light eFoiling.
The Foil Drive Assist MAX is perfectly suited to those looking for extra thrust for heavier riders or smaller boards and foils, longer ride times and ultimate flexibility of how you choose to foil. Surf, Wing, Downwind, Wake and Flatwater, the Assist MAX does it all!
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!
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!
Gen2 Motor Systems are available in different lengths that are interchangeable. The MAX comes with the 20cm Cable. 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:
Are batteries cross-compatible?
Foil Drive batteries are NOT cross compatible across units ie. An Assist battery cannot be used in an Assist PLUS. Max batteries cannot be used in Slim units etc.
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.
Whats the difference between the Assist Max and Fusion?
The Assist MAX is the all-rounder that balances power, weight, and runtime for all riders and disciplines. It is lighter and more versatile, making it ideal for everyday use and travel. The Fusion provides maximum power and runtime, offering eFoil-like performance for longer sessions or heavier riders, but it is heavier overall.
