Fluid Exercise E685 Arm Cycle

The Fluid Exercise E685 Arm Cycle is a compact, robust upper-body ergometer that is just as at home in a high-performance environment as it is in a rehabilitation room. Thanks to a wide resistance range, you can switch effortlessly between intense HIIT intervals and gentle rehabilitation or warm-up sessions, with a smooth, natural motion that responds instantly to your effort.

At the heart of the E685 is the patented twin-tank Fluid resistance system with 10 adjustable levels. The fluid resistance responds smoothly and progressively to your speed: the harder you pedal, the more resistance you feel. This allows you to train at your own level, from the first tentative revolutions to explosive, ballistic sprints.

Key features

• 10 levels of Fluid resistance – the patented twin-tank system delivers smooth, progressive resistance that you can adjust with a simple turn of the knob, suitable for every training level.
• Bidirectional training – pedalling forwards and backwards activates different muscle groups and promotes balanced strength development in the shoulders, arms and upper back.
• Built for performance and rehabilitation – maintains smooth resistance at all speeds and intensities, from steady-state recovery to maximum effort.
• Interactive performance monitor – track your effort in real time, with Bluetooth connectivity and heart rate compatibility for targeted, measurable training.
• Core and shoulder support – the movement engages the core and supports the shoulder girdle, promoting good posture and full-body integration.
• Compact footprint – with a footprint of over 2 m², the E685 fits into group exercise studios, physiotherapy practices and commercial fitness centres.

Who is the E685 suitable for?

The Fluid E685 is designed for standing use and engages long kinetic chains: the shoulders, core and upper back work together in a functional movement. This makes the machine highly versatile – for athletes looking to build upper-body fitness and strength, for cardio training, and for rehabilitation where controlled, consistent resistance is important.
