Foil Drive Fusion

The Fusion delivers similar power and runtime to an eFoil, but without locking you into a single riding style. You can switch cable lengths and ride it as a powerful foil assist, giving you far more flexibility across surf, wing, downwind, wake, and flatwater.

Yes. The Fusion is ideal for learners thanks to its longer runtime, smooth power delivery, and optional tilt sensor that automatically cuts the motor if you fall. It allows riders to progress at their own pace with added confidence.

Runtime varies depending on rider weight, skill level, board and wing size, throttle use, and water and weather conditions. The figures below are indicative real-world averages.

Fusion 860 Battery

E-Foil

• Intermediate: ~39 minutes
• Advanced: ~61 minutes

Surf

• Intermediate: ~50–80 minutes
• Advanced: ~80–110 minutes

FM+ 650 Battery

E-Foil

• Intermediate: ~29 minutes
• Advanced: ~48 minutes

Surf

• Intermediate: ~40–50 minutes
• Advanced: ~55–70 minutes

How are these runtime figures measured?

The E-Foil figures are based on an 85 kg rider using an 800 cm² wing and 5'0" 40 L board in flat-water conditions, with the throttle at approximately 70%. An intermediate rider will typically have multiple touch-downs, falls and restarts, while an advanced rider has no touch-downs or falls.

The Surf figures are based on an 85 kg rider using an 800 cm² wing and 5'0" 40 L board in approximately 3 ft swell with less than 5 knots of wind. An intermediate rider has high motor reliance and does not pump between waves, with multiple falls and restarts. An advanced rider has medium motor reliance, links some waves by pumping, and has minimal falls and restarts.

Please note: Runtime can vary significantly depending on rider weight, skill level, gear sizing, throttle use, wave conditions, wind and other environmental factors. These figures are intended as an indicative guide based on real-world averages, not a guaranteed runtime.

The Fusion delivers the same power and thrust as the Assist MAX+. With the Fusion 860 battery, it offers longer runtime, while pairing it with the FM+ 650 provides the same power, thrust and battery capacity as the MAX+ with FM+ 650.

Compared to the Assist Slim, the Fusion delivers approximately 40% more power and thrust, making it better suited to heavier riders, smaller boards, higher speeds and more demanding conditions.

Yes. That’s exactly what it’s designed for. By adjusting your setup (primarily cable length), the Fusion transitions between a high-power assist system and an eFoil-style riding experience.

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.

Assist Slim is the lightest system and ideal for shorter, more agile sessions, while the Fusion provides maximum power and runtime, offering eFoil-like performance for longer sessions or heavier riders, but it is heavier overall.

Each Foil Drive system offers a different balance of weight, power, and runtime.

Assist Slim is generally for the performance rider wanting assisted pop-ups only.

The Assist MAX+ provides a balance of power and endurance for all-round use.

Fusion offers the power and runtime of an Efoil with the lightness and adaptability of an Assist.

We do not currently have travel batteries for the gen2.5 Foil Drives. However, we are working on a solution for travelling with your Foil Drive.
