Lightning Bolt Trench

Lightning Bolt Trench

Lightning Bolt Trench

Designed specifically for the Foil Drive Gen2 and Gen2.5, the Lightning Bolt Trench combines the proven performance of the Lightning Bolt with an integrated trench to improve clearance around the Foil Drive unit. The trench helps the board plane earlier with less drag and reduces drag on touchdowns.

The design features a straighter tail rocker without a pronounced tail kick, helping the board lift onto foil in a more horizontal position. A rounded-square tail adds volume where it's needed to support a balanced takeoff.

The adjustable mast position accommodates different rider experience levels, with a rearward position for beginners and a more forward position for experienced riders who prefer a shorter-board feel.

Amundson's Signal Windows provide a clear connection between the Foil Drive unit and controller. The design also allows easier movement of the mast and unit for customers who choose not to use the supplied foam inserts.

Lightning Bolt

Designed for the Foil Drive Gen2 and Gen2.5, the Lightning Bolt focuses on balanced takeoffs and efficient performance in a compact board shape.

Its straighter tail rocker, without a pronounced tail kick, helps reduce the tendency for the nose to lift excessively under acceleration. The rounded-square tail provides additional volume to help the board transition onto foil in a more horizontal position.

The adjustable mast position allows riders to fine-tune the board to their experience and riding style. Amundson's Signal Windows also provide a dedicated connection between the Foil Drive unit and controller, while allowing easier adjustment of the mast and unit.

1. Choose Your System

You’ll need to decide between the Fusion, MAX+ or Slim Foil Drive. The Fusion is our most powerful system. With the power and runtime of an Efoil, the lightness and adaptability of an Assist, the Fusion earns its name as the perfect blend of both worlds. The MAX+ is our most popular kit, designed as the ultimate all-rounder with extended runtime and plenty of power for every session. The Slim, is a lightweight option created for riders who want a minimal setup and quick bursts of performance.

2. Choose your battery

Each system can be paired with different battery sizes to suit how you ride. Larger batteries deliver longer runtime, while smaller batteries keep the weight down, perfect for performance foiling and a more agile feel on the water. Whether you’re chasing endurance or chasing waves, the right battery choice ensures your Foil Drive moves with you.

3. Choose Your Motor

Your motor sets the tone for your ride. The Standard motor is great for most ride styles, or if you’re chasing longer runs, more torque, and that extra surge of power, the High-Power motor is your upgrade. Some products come standard with the High Power Motor (Aluminium Integrated), where as others you'll need to add to cart, check product inclusions for more!
