K4 Series

The Tedgix K4 Series is an electric propulsion platform for kayaks and stand-up paddle boards, evolving from the original EDGE Smart Drive K4. The lineup includes K4C Cruise for lightweight everyday cruising and K4S Sport for fishing, touring, and higher-performance use, helping riders choose the right motor and battery setup for their needs.

3 Products

The Tedgix K4 Series is built as a two-model electric propulsion platform for kayaks and stand-up paddle boards. Instead of using a one-size-fits-all approach, the series separates everyday cruising from higher-demand fishing and touring use.

K4C Cruise is designed for lightweight everyday cruising, casual paddling, and users who want a simple electric assist setup. It works with Tedgix B2, B4, and B8 batteries, allowing riders to choose the balance of portability and runtime that best fits their typical use.

K4S Sport is designed for fishing, touring, longer sessions, and users who need more performance and control. For international orders, K4S currently ships with the 1526Wh B15 battery and dedicated 819W charger, with a higher-capacity B30 battery option planned for the future.

Together, K4C Cruise and K4S Sport give users a clearer way to choose between lightweight cruising and higher-performance electric propulsion. Whether you are looking for an electric kayak motor, an electric SUP motor, or a more capable setup for fishing and touring, the K4 Series provides a dedicated option for each type of use.
