Pedal Across the Water With the Red Shark Inflatable Water Bike
The Red Shark Water Bike combines bicycle-style pedaling with a rigid inflatable paddleboard platform to create a stable, portable inflatable water bike for lake cruising, fitness, exploration and outdoor recreation.
Unlike a traditional bicycle, the Red Shark bike transfers pedal power through a sealed underwater gearbox to a submerged propeller. Pedal forward to move ahead, pedal backward to reverse, and steer with the handlebar-controlled rudder.
The wide drop-stitch inflatable board provides buoyancy while the adjustable stable-rudder system helps improve directional control and roll stability. When the ride is over, the board can be deflated for transportation and storage.
Choose from the comfortable Enjoy, sport-focused Fitness, gear-ready Adventure, or electrically powered Scooter. These Red Shark Bikes give lakefront owners several different ways to enjoy the same versatile inflatable watercraft platform.
If you're looking for fun water toys for adults that provide more activity than simply floating, the Red Shark Water Bike delivers a unique mix of cycling, exploring and time on the water.
Ride the Red Shark Bike Like a Bicycle on the Water
Inflatable Portability With Bicycle-Style Controls
The Red Shark Bike Surf platform combines the buoyancy of an inflatable SUP with a self-supporting bicycle frame and underwater drivetrain.
On the pedal-powered models, each turn of the pedals is transferred through a sealed 1:10 ratio gearbox to the submerged propeller. There is no exposed bicycle chain running through the water.
The rudder performs multiple jobs by helping steer the Shark bike, protecting the propeller and adding lateral stability beneath the board.
The result is a water bike that feels familiar to anyone who has ridden a bicycle but opens up an entirely different way to explore lakes, calm rivers, marinas and suitable coastal areas.
Recreational Cruising
The Enjoy model is built around a relaxed riding position for comfortable lake exploration.
Fitness Riding
The Fitness model offers a sport-oriented riding position and multiple propeller choices for different effort levels.
Adventure & Fishing
The Adventure model adds storage features for riders who want to carry gear on longer outings.
Electric Scooter
The Scooter replaces pedal propulsion with an electric rudder motor and wireless power control.

How It Works
How Does the Red Shark Water Bike Work?
- The inflatable board supports the rider.
Drop-stitch construction becomes highly rigid when properly inflated. - You pedal the bike frame.
The pedals turn the internal drivetrain just like starting to pedal a conventional bike. - The gearbox multiplies rotation.
A 1:10 transmission converts pedal rotation into faster propeller rotation. - The underwater propeller creates thrust.
The propeller pushes water rearward to move the inflatable water bike forward. - The rudder controls direction.
Handlebar steering moves the submerged rudder to turn the watercraft. - Pedal backward to reverse.
The drivetrain allows low-speed reverse maneuvering without a separate transmission lever.
Rider Fit & Capacity
Red Shark Bike Rider Fit
Adjustable Frame
The multi-size chassis is designed to accommodate a wide range of rider heights.
