wr4 air

The toning aquabike


The ultra light aquabike that motivates to fitness training

The WR4 Air is equiped with hydraulic resistance. It is particularly popular amongst health specialists such as physiotherapists as it stimulates blood circulation in the legs, ideal for physical rehabilitation and when renewing fitness exercice.

The central hydraulic resistance system is composed of cups, which orientation can be adjusted. With a movement of the hand, easily turn the cup horizontally or vertically to adjust effort during training. The lower body firms up harmoniously with training for assured energy gain.

Aqua Double Speed pedals complete the variable hydraulic resistance on the WR4 Air. By deploying the pedals flaps, the contact surface with the water is increased and pedalling effort doubles up.

With an anodized aluminium structure, the WR4 Air can be easily moved. Two silicone wheels and four suction cups help with moving and securing the aquabike in the pool without any risk of marking the floor. Adjustement of the pedals, the saddle and the handlebars in height and in depth personalize the aquabike to the user.

main features

aluminium structure

With its aluminium range, Waterflex introduces a new dimension to aquafitness: a featherweight aquabike with which organising a training course becomes a breeze.

Aluminium is a metal issued from quality alloys. T6 aluminium that Waterflex uses is of premium quality. It is mainly composed of a magnesium and silicon alloy that can be anodized in order to protect it against corrosion.

To reinforce its resistance to corrosion, Waterflex aluminium range is anodized at a strength of 25µm, meaning a Class 25 for industrial use. n. Its high anti-corrosion capacities are an important advantage in terms of resistance to humidity and water.

hydraulic resistance

Hydraulic resistance is powered with a blade system that resembles that of a water mill: the blades use the force created by mixing the water.

Hydraulic force effects lie in the duration of the training sessions and in the intensity of the effort.

aqua double speed pedals

Amplify your cardio session.

These ultra-innovative pedals use a new technology to increase resistance for even more sport. The lateral flap folded under the pedal offers ideal resistance at warm-up stage. To boost your training, unfold the flap in order to widen the area in contact with the water and double your effort.

The flap locks in a single movement and increases the Aqua Double Speed pedal hydraulic resistance by 54%.

aquabike category: Enduro

Accessible to all, the Enduro type of exercise is ideal for gentle fitness sessions and water rehabilitation.

Waterflex aquabikes comprising variable hydraulic resistance have been specifically designed for Enduro sessions enabling gentle work on the figure by stimulating blood stimulation.

Perfectly adapted to aquatic rehabilitation and group sessions, Enduro aquabikes are the ideal choice for private use, hotels and campsites.

adaptative ergonomics

With adaptative ergonomics and its 6 adjustments axes as well as a Click&Turn system, the aquabike can be adjusted to any body type and pool depth. The aquabike's saddle and handlebars can be modulated in height and in depth.

Reference marking allows the position of the saddle and handlebars to be changed for maximum use comfort.

anode sacrificielle
Sacrificial anode

Its composition resulting from Zinc alloy acts through electropositivity and early oxydation to protect the frame and metal parts.

drainage express
Express drainage

A perforation system strategically placed along the aquabike's frame helps to express drainage of the water. The bike is easily removed from the swimming pool in a few seconds.
