Bixpy from San Diego, California has developed an electric SUP conversion kit that can be used for Stand Up Paddle Boards and Kayaks.
The small portable motor was originally funded on on Indiegogo in November 2016 reaching 398% of funding with 167,474 USD. The Bixpy jet operates in fresh and salt water and weights just above 1 Kg or 2.2 pounds, but is still supposed to generate enough power to transport 2 adults in a kayak against wind and waves.
Unfortunately Bixpy is not giving more information about the speed for an E-SUP nor the distance which can be achieved. We have contacted the manufacturers and will update once the information is available.

The rechargeable lithium ion batteries offers 404 watt at 25.9 V and 15,600 mAh. It takes 4-5 hours to charge the battery with a standard Bixpy 3A charger. The battery shall last for „several hours“, whatever this means.
The battery is good for 500 to 800 full charges. The electric SUP conversion kit is using impellers instead of propellers for safety reasons. In addition multiple auto switch off features are included. For example a magnetic kill switch. The Paddle Board Jet sells for 999 USD and can be connected like standard fins to your existing SUP Board.

In case you have no fins there is an optional Bixpy Kit available which basically can stick to any board. The wireless remote with a battery charge indicator controls the speed while you use the paddle for sharper turns and lean your body for broader turns. You can select between 10 speeds forward and 3 speeds reverse.
The remote is waterproof, but does not swim. You attach it to the Paddle or your wrist.

We will request more data from the manufacturer about this electric SUP kit, but the current data can be compared with other Jet SUP boards in our E-SUP comparison.
