A question I have heard for twenty years, in slightly different words each time, goes like this: "Is FES cycling actually doing anything, or is it just an expensive way of making my legs twitch?" Even worse is when this is what the user thinks but doesn't say out loud.
It is a fair question, and the answer takes a bit longer than a simple yes or no. We were introduced to FES cycling many years ago by the Director of the Scottish Spinal Injuries Unit, David Allan. In collaboration with Professor Ken Hunt at Glasgow University and an enthusiastic group of PhD students, they had carefully examined the benefits of FES cycling for persons coping with a neurological condition, such as a spinal cord injury. The Glasgow team, a group from University College London, and a number of other groups around the world had established a number of benefits from using FES cycling, but we were to get involved in its commercialisation with our German partners, Hasomed GmbH. Our collaboration was strong from the beginning and has endured over the years; however, when we started offering this technology to the public, my biggest concern was: would people use it? Will they feel the benefits of it?
Although the technology is beneficial for most neurological conditions, the majority of our clients will come to us because they have experienced a spinal cord injury. The cost of these systems can be beyond the means of many private payers. It is likely that the majority of our clients will have funding from insurance or the medical-legal process. The fact that these agencies do provide funding should give clients a measure of reassurance that the research evidence behind this technology is strong.
It's fine for us to talk about benefits such as bone density, improved metabolism, and improved cardiovascular fitness, but clients need to feel something. They have to trust in the process, and clinical benefits sometimes seem a little nebulous to clients. It comes down to trust in their clinical advisors and, to some extent, in us.
So I completely understand and welcome scepticism about the technology. They are being careful with their money, careful with their time, and quite often, they have already been burned once or twice by a rehabilitation kit that did not deliver. I go into lots of homes where that standing frame serves as a clothes horse, sitting in the corner of the room.
The rehab technology sector has not always covered itself in glory. There are products on the market that promise far more than they deliver, and it's important not to sell a bike to anyone who can pay for one. So a healthy dose of scepticism is, in my view, exactly where you should start.
What I want to do here is separate two different questions that often get tangled up. The first is: "Does FES cycling do something biologically real?" The second is: "Will it do something useful for me, in my situation, that justifies the cost?" The first one has a clearer answer than the second, and it is worth touching on both.
If you spend any time in UK forums for spinal cord injury or MS, you will see FES cycling come up periodically, and you will see a fairly consistent reaction. Someone asks about it; someone else replies that it is a gimmick or marketing dressed up as therapy; a third person says it changed their life. The reader is left no clearer than they started. Of course, every individual has unique challenges and comes with different expectations. A careful individual assessment is always necessary to manage expectations.
For years, FES cycling was marketed in some quarters as a path back to walking. It is not, for the great majority of users with a complete or near-complete spinal cord injury. When the headline does not match reality, people quite reasonably feel misled, even if the technology has other genuine benefits.
Second, people confuse FES cycling with passive movement bikes, with TENS pads, and with consumer-grade muscle stimulators that they have seen advertised online. These are not the same thing. They produce different effects, they cost different amounts, and they are aimed at different problems. A bad experience with one of them is often misread as a verdict on all of them.
Third, in most parts of the UK, the NHS does not fund FES cycling. The unstated assumption many people draw from this is: if it worked, the NHS would offer it. That is not how NHS commissioning decisions are made, but the inference is understandable.
Add those together, and you get a scepticism that is partly earned, partly inherited, and partly a misreading of the evidence. So let us look at the evidence.
There is a body of peer-reviewed research now stretching back several decades, including a substantial systematic review published in the Journal of NeuroEngineering and Rehabilitation in 2021. I will not pretend it is settled science across every outcome, but a few things are no longer in serious dispute.
Cardiovascular conditioning. In people with mid- to high-level spinal cord injury, the major problem with cardiovascular fitness is that there is not enough working muscle below the spinal cord lesion to drive the heart rate up. FES cycling addresses this by recruiting the large muscle groups in the legs to perform active work. Heart rate rises, oxygen uptake increases, and over weeks of consistent use, you see the same kind of cardiovascular adaptations you would expect from any aerobic training programme. This is well established.
Muscle preservation and, in some cases, muscle growth. Paralysed muscle wastes quickly. FES cycling slows that wasting and, in many users, reverses it. Cross-sectional muscle area increases over the first few months of consistent use. We have measured this with our own clients many times.
Bone density signals. This one is a little softer than the muscle data, but the direction of travel is consistent. Loaded contractions performed through the legs appear to slow bone density loss in some users, particularly at sites loaded during the cycling stroke. It is not likely to reverse osteopenia, but it is a meaningful contribution to a long-term bone health strategy.
Spasticity reduction. Many users notice their spasticity is calmer for hours after a session. This is consistent with the research, and for some users, it is the single most valuable thing FES cycling does for them. With the Stim2go you can now combine FES cycling with transcutaneous spinal cord stimulation (tSCS) and this can have a very powerful effect on spasticity and even neuropathic pain. The effects are cumulative, and regular sessions lead to longer lasting results
Secondary health benefits. Improved circulation, reduced lower-limb swelling, better sitting tolerance, and fewer pressure-related skin issues over the long term. These outcomes are harder to quantify, but they show up reliably enough in clinical experience that I would not leave them out.
KEY POINT: When people say "FES cycling does not do anything", they are almost always wrong about that part of the question. It does plenty. Whether it does enough for you to justify the cost is a separate question.
There are claims I treat more carefully.
Functional improvements (more voluntary movement, better trunk control, occasional gains in walking ability) are real for some users with incomplete injuries, but the evidence is mixed and individual variation is enormous. I have had clients who surprised me with how much they recovered. I have had clients who did everything right and saw very little change in voluntary function. Both are normal.
Neuroplastic effects, particularly when FES cycling is combined with newer modalities such as tSCS are an active area of research and look genuinely interesting (even exciting). But this is not the key part of the story I would buy a bike on, today, in 2026. It is the part of the story I would keep an eye on.
If anyone tells you FES cycling will make you walk again, they are either misinformed or being dishonest with you. That is not what the evidence supports for most users.
Patterns I see over and over:
The clients who get the most from FES cycling are usually the ones who treat it as a long-term programme, not an acute intervention. They use it three or four times a week, for months and then years, at intensities that are sustainable. it's the volume of the work that is done that counts. They notice changes in fitness, body composition, spasticity, and energy levels long before they notice anything that looks like functional recovery. It comes down, for many people, to subtle feelings of being better. Many of them never expect functional recovery, and they are not disappointed when it does not come, because their goal was always long-term health.
The clients who drift away from FES cycling are usually the ones who came in expecting it to do one specific dramatic thing, did not see that thing in the first three months, and concluded it was not working. In hindsight, the early signs of benefit were almost always there. They were just not the signs the client was watching for.
The clients I worry about are the ones who were sold a system without a proper assessment, with no follow-up, and no one to ring when something went wrong. Those clients tend to have expensive equipment sitting under a sheet in the spare room, and they are entirely justified in being cynical about the industry that put it there.
This, in my experience, is the part that matters most, and it is the part the marketing rarely talks about.
A worthwhile FES cycling programme has four things going for it. A proper pre-purchase assessment is necessary to ensure the equipment is matched to the user and that the goals are realistic and meaningful. A structured starting protocol, so the early sessions build confidence rather than fatigue. Genuine support after the sale, so when something stops working, there is someone to ring. And a long-term plan, so the programme is part of a wider approach to health rather than a standalone purchase.
A programme that sucks is one that skips one or more of those. Sometimes all four.
You can have the best equipment on the market and a programme that sucks. You can also have modest equipment and a programme that runs for fifteen years and changes someone's life. The equipment matters, but the wrapper around it matters more. Any of the FES bikes on the market in the UK will do a job for you. You need to look a little bit beyond the hardware
No. The biology is real. The evidence base for the well-established benefits is solid. The technology has been refined over forty years, and the current generation of systems is better, more accessible, and easier to live with than anything that came before.
But "not a gimmick" is not the same as "the right purchase for you". Whether FES cycling is right for your situation depends on your level of injury, your goals, your budget, your home setup, and the level of support you can provide. That is a conversation, not an article.
If you are sitting on the fence, the next step is not to buy a system. It is to get a proper pre-purchase assessment. A good assessment will tell you whether you are a suitable candidate, what realistic outcomes look like for your situation, and whether the cost is justified given your goals.
If you would like to talk through your situation, please get in touch. We are happy to have the conversation, even if it ends with us suggesting that FES cycling is not the right answer right now.
