Whether you are cruising above the waves or diving below them, power matters. So do range, control, and portability. The Asiwo U1 delivers on all of these and goes even further.
This is not just an underwater scooter. It is a 2-in-1 propulsion system built for both underwater exploration and surface mobility, transforming your snorkeling sessions, SUP rides, and kayak trips into fast, efficient adventures.
For anyone looking for a high-performance, multi-sport, travel-ready electric water scooter in 2025, the Asiwo U1 is one of the smartest upgrades you can make.
Serious Power in a Streamlined Form
Equipped with a 1100W brushless motor, the U1 delivers up to 17 kilograms of thrust. It reaches underwater speeds of 10 feet per second, and even more when mounted to a paddleboard or kayak.
You get three speed modes, easily controlled through a dual-trigger system:
-
Slow (6 kgf): 57 to 60 minutes of runtime
-
Medium (12 kgf): 27 to 30 minutes
-
Fast (17 kgf): 15 to 18 minutes of peak power
Whether you are gliding over coral or powering through current, the U1 gives you responsive control without breaking stride.
Dive Deeper, Paddle Further
Most scooters are built for one purpose. The U1 is built for both. It adapts seamlessly to underwater and surface use.
Underwater: Designed for snorkeling, freediving, spearfishing, and shallow scuba. Rated for depths up to 50 meters (164 feet), it extends your reach and reduces fatigue.
Surface Mode: Attach the U1 to your SUP or kayak using the included fin adapters. It is compatible with over 99 percent of fin box systems, including Slide and Lock, Flip and Lock, and US fin boxes. On the surface, the U1 delivers steady, smooth thrust that is perfect for touring or paddling against headwinds.
