Specialist FES cycling, since 2003

FES Cycling
and much more.

Functional Electrical Stimulation cycling uses small electrical impulses to activate paralysed or weakened leg muscles, so you can pedal a stationary bike and get active exercise. Until now, this meant buying a complete system built for that one purpose. PAJUNK® Stim2Go changes that. It pairs with almost any cycle ergometer, works standalone for functional training, and supports tSCS protocols. All controlled through an app that keeps the device up to date as the evidence evolves.

The technology, briefly

What FES cycling actually does.

Paralysis or weakness due to a neurological condition limits the active exercise we can participate in. FES uses small, programmed electrical impulses to activate paralysed or weakened muscles, producing co-ordinated movement on a stationary bike. Regular FES cycling has been demonstrated by extensive research to support cardiovascular health, muscle mass, bone density, and circulation.

The evidence is strongest for people who maintain a consistent programme over months and years. The honest summary: outcomes vary between individuals, but the trajectory for those who stay with it is positive.

The people behind it

It is not just the device.
It is who sets it up.

When you invest in a medical device, what often matters most is what happens after the purchase. Who assesses your situation. Who sets it up in your home. Who picks up the phone when something is not right. For FES cycling in the UK, that is us. We have been doing this work for over twenty years, and we still answer the phone ourselves.

Whatever your condition and wherever you are in your journey, there is always reason to pursue better health. The right knowledge, the right technology, and the right support can make a meaningful difference.
