The 17 kgf thrust on the Asiwo is significantly higher than what is available in the market - if you are going tandem, you have a heavy kayak or boat, or you just want to have serious fun, you can. Note that there are 3 speed levels, so you can just cruise as well.
The hydrodynamic design gives the U1 15% more thrust but uses 20% less energy than previous designs. The 180Wh battery is capable of longer trips, especially on the lower power setting.
Modular set up means you can easily take it apart to remove debris. This is a common issue that causes the motor to seize in other models.
Auto cut-off on remote - if you go overboard, your kayak won’t keep zooming away from you! Fully waterproof battery casing.
