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.
Who we work with
Conditions we support.
FES cycling can support people across a range of neurological conditions. Every situation is different. We help you understand what is realistic for you.

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.

The Cauda Equina Question: Why FES Cycling Will Not Help You, and What Will
If you have a cauda equina or conus injury, the FES cycling literature does not really apply to you. The good news is that there is a different kind of stimulation that does, and most UK readers have never been told about it.

FES Cycling After Stroke: What the 2026 Evidence Actually Supports
Two 2026 systematic reviews push back on broad claims for FES cycling in stroke, but a clearer, narrower case remains: subacute trunk control, walking endurance, and an aerobic dose delivered at lower perceived effort.

The Stim2go Transition: What Changes for Physios Who Built Their Practice on RehaMove
Eighteen years with the RehaMove leaves a clinician with a lot of accumulated competence. Most of it carries straight across to the Stim2go. A small amount needs recalibrating. A smaller amount is genuinely new. This article sorts which is which.
