New Design, New Innovations

The WR4 aquabike combines the seduction of its design, technical innovations to simplify its use, redesigned ergonomics , all with a much appreciated lightness .
The great modularity of the settings offers a variety of positions which improves comfort and sensations while respecting the joints. The biomechanics of pedaling are respected to adjust their training and exercises to the constraints of each individual's templates (see ERGO RIDE Innovation). You work in safety.

Aquapalm 2

New Aquapalm 2 system

The WR4's " Aquapalm 2 " System consists of 4 fins with a reworked design to increase performance. The bucket shape provides additional pressure on the water and increased resistance, this hydraulic resistance system can be modified by the user by performing a rotation from the seated position of each of the fins. This technical progress has won over sports, physiotherapy and thalasso clubs.

7 Muscle group

7 muscle groups

The WR4 allows you to work on endurance, keep fit, work on the cardiovascular system, work on respiratory capacity. It offers a complete and effective workout , the 7 muscle groups are called upon: mainly the quadriceps , calves and harmonious toning of the glutes, thighs and abdominals , as well as the upper body . This contributes to a refined and toned silhouette .

AquaSpeed 2

New AquaSpeed 2 pedals

WR4 is equipped with new thermo-molded AQUASPEED 2 pedals , more anatomical with fixed strap (from 36 to 44). They accentuate the effect of resistance by reinforcing the pedaling forward or backward. Its use is always barefoot for more comfort .

New Sport handlebars

New Sport handlebars

Thanks to the new handlebar design, WR4 offers three different training positions to suit individual needs: a standard option , a city bike option and a challenging racing position. The positions are more natural, the grip easier for maximum comfort, especially in the race position.

Superior ergonomics

Superior ergonomics

The distance between the feet and the saddle has been reduced for a more realistic feeling and so that the aquabiker is more in harmony with his device. Biomechanics have been respected to be in line with the anatomy of each.


Marking Reference

Maximum user comfort has been obtained thanks to the introduction of a new reference marking allowing the position of the saddle and the handlebars to be changed without disturbing the rider. Precise position adjustment is guaranteed by steps of 0.5 mm.

Express Drainage

Express Drainage

Thanks to the new perforation system , WR4 offers express water drainage. This technical innovation is unprecedented, it is a revolution that lightens your aquabike to facilitate exits from the pool .

Express Drainage

Sacrificial anode

A sacrificial anode is installed on the WR4 to protect it from corrosion. The anode is a softer metal which will corrode in its place and provide maximum protection in salt water or salt chlorination treated water.

Ergo Ride

Ergo Ride

Better knowing the biomechanics of pedaling allows the aquabiker to optimize his movement in order to acquire a better performance, to avoid certain pathologies and to adjust his training by the design of adapted exercises allowing to improve certain parameters such as the strength, velocity or coordination. This is the reason why WATERFLEX in coordination with its R&D team , and its partners (coach and physiotherapist) has developed a range of Pro aquabike redesigned to be more in line with the biomechanical constraints of the aquabiker . This new range benefits from ERGO RIDE technology with ergonomics specially designed to optimize the biomechanics of pedaling and respect each person's anatomy while reducing constraints.

100% stainless steel


All our equipment is designed in high quality AISI 316L steel, with anti-corrosion protection treatment according to the international standards in force.
