EDGE K4 electric motor for SUP and kayak

Edge K4 electric motor – Powerful, light and smart for SUP and kayak

The Edge K4 electric motor is a powerful and lightweight motor that transforms your SUP board or kayak into a small electric craft. With an efficient 400W brushless motor and 9.3 kg (20 lbs) of thrust, you get comfortable, effortless propulsion – whether you’re on a long trip, fishing or just cruising around.

Speed ​​and range

The engine delivers a top speed of up to 9.6 km/h (6 mph), depending on boat type, weight and conditions. This allows you to cover longer distances, maintain a higher cruising speed and get home safely even in challenging headwinds or currents.

Intelligent control with Bluetooth

The Edge K4 is controlled with a wireless Bluetooth remote that easily attaches to your paddle, wrist or vest. Here you can adjust the speed steplessly and activate cruise control.

Unique steering function: Unlike FinDrive, which is steered with a rudder, the entire propeller assembly on the Edge K4 pivots (±35°). This integrated steering function acts as an active assistant, helping you stay on course and maneuver precisely without having to constantly correct with the oar.

Universal mounting and flexibility

The system is universal and installs in minutes. It fits most inflatable SUP boards and kayaks with standard US fin box or 9" slide-in mount. The motor is very compact, and you can choose from several battery sizes based on your range needs.

Edge K4 is perfect for those who want to:
– make longer trips more comfortable
– have extra safety and power in headwinds and currents
– fish more efficiently without paddling all the time
– use a packraft, SUP or kayak as a “mini-boat” with electric propulsion
This is a serious, yet playful upgrade to your equipment – ​​you get the feel of a small electric motorboat, but with the freedom and quiet of SUP and kayaking.
