The Motorized Technology is an optional extra which can be added when purchasing an Exerfly Platform or Rack Mount. The Motorized Technology is included in our advanced packages for the Platform and the Rack-Mount.

Exerfly’s Motorized Technology is used to provide an eccentric overload during the eccentric phase of movement. This is done by adding the energy from the Flywheel speed to the eccentric phase of a movement, making it greater than the concentric phase. The rate of overload is selected by the user and is based on their input force during the concentric stage. From the Exerfly app, users can choose an eccentric overload of up to 80%. Once the desired setting is selected, the motorized technology will apply the additional percentage boost to the Flywheel in the eccentric phase of the movement. For example, if the Eccentric Overload Boost is set to 20%, the flywheel will be given 20% more energy during the eccentric phase of a movement, than it had in the concentric phase. The flywheel will spin 20% faster in the eccentric phase, and the user will get an eccentric overload. The statistics in the app will reflect this.

When first using the Exerfly’s Motorized technology, we recommend starting between 1-5% to get used to the feeling. Using the eccentric boost amplifies the energy of the Exerfly during the eccentric phase, which increases the intensity of the workout. It is important to start low and ease into it to avoid any injuries. The motorized technology is not recommended for users without a reasonable level of strength and fitness. Make sure you've warmed up correctly and started conditioning before attempting to use the motor boost. Always start with a low Eccentric Overload Boost setting, between 1-5%. Improper use can cause significant injury. Because smaller flywheels spin much faster than bigger flywheels, using small inertia flywheels with a high Eccentric Overload Boost setting can be dangerous. Motorized technology is not recommended for injury management, rehabilitation, the elderly, or users without a reasonable level of strength and fitness.

1.Select your desired eccentric overload setting on the Exerfly app.

2.Press the circular icon next to the Eccentric Overload Boost setting, this will engage the motor.

3.Once the button is pressed, the Exerfly will count down from 10 seconds, and the short, sharp beeps will get quicker and quicker.

4.Once the beeps have stopped, the rope will wind up and will pull you into your starting position.

5. For WiFi connections, hold position until you hear two short beeps. For Bluetooth connections, you can move straight away.

6.You are now ready to start your exercise - make sure you start slowly, as the Eccentric Motor can be quite a shock if you are not used to it.

The workout statistics on the Exerfly app will reflect the additional energy provided by the motorized technology. The statistics are recorded from the moment you press the Start button, and will generate live feedback for each rep. The motor will automatically stop when either the set number of reps have finished, or the Stop button is pressed. The windup button will need to be pressed again to enable the motor and start the countdown. If the Start button for the statistics is not pressed, the user can use the Eccentric Overload Boost setting as much as they want without it stopping/needing to be restarted. Users can also change the eccentric boost percentage settings through the Exerfly app.

Make sure you've warmed up correctly and started conditioning before attempting to use the motor boost. Always start with a low Eccentric Overload Boost setting, between 1-5%. Improper use can cause significant injury. Because smaller flywheels spin much faster than bigger flywheels, using small inertia flywheels with a high Eccentric Overload Boost setting can be dangerous. Motorized technology is not recommended for injury management, rehabilitation, the elderly, or users without a reasonable level of strength and fitness. Eccentric overload training is very beneficial but also very fatiguing, so you will likely exhibit muscle soreness over a few days if you are not used to it. This is called delayed onset muscle soreness (DOMS).

The eccentric boost created by Exerfly’s motorized technology is intensive, and is not recommended for untrained, injured, or elderly users. With traditional Flywheel training, resistance is based on how much effort is put into the concentric phase of movement. The harder you pull, the harder it pulls back. With the motorized boost, the eccentric stage is even more significant than during the concentric. Using the Eccentric Motor, the speed of the Flywheel is increased during the eccentric phase, meaning it takes significantly more strength to slow down. So, if you put a reasonable amount of effort into the concentric phase, then the eccentric phase is going to feel a lot harder. Use a bicep curl as an example. In the concentric phase (muscle-shortening phase, or the ‘up’ motion of the curl) you expend a certain amount of force. Without the motor, that same amount of force would be mimicked in the eccentric phase (muscle-lengthening phase, or the ‘downwards’ motion of the curl). However, with an eccentric overload set at 20%, the bar will be pulled down 20% harder than the upward motion, intensifying the movement significantly.
