We first started to work with FES cycling around 17 or 18 years ago now. We were told that many people with MS would be our clients. Actually that hasn't been the case, largely because the cost of most FES cycling systems were unaffordable. We couldn't help them. As we've started to work with the Stim2Go, we've found many more of our clients now have MS. They've been able to use the Stim2go for FES cycling and much more.

Most people with MS who own a motorised passive-active bike did not start out with one. They started with an ordinary exercise bike, and at some point it stopped being usable. They could no longer get on the upright one. The standard bike became unusable because they could not generate enough momentum. Their feet would not stay on the pedals, or a heel kept catching the frame, or tone made the whole thing impossible. A MOTOmed or a THERA-Trainer, with a motor that moves the legs when they will not move on their own, was the answer to that problem, and for many people, it has been a good one.

The question this article answers is whether the electrical stimulation you may have seen on a bike in a rehabilitation gym can be added to the bike you already have at home, and whether it is worth it. The Stim2Go, a very flexible yet powerful stimulator, is not tied to any bike. Let's look at what the evidence supports.

Many people have a motorised passive-active bike at home. They use it for a year or two, usually a MOTOmed or a THERA-Trainer, and they use it most days. Their legs go round. The question is whether their legs are getting anything from it beyond going round, and whether the electrical stimulation they saw on the bike in the spinal unit gym could ever come home.

Passive cycling does beneficial things, and adding synchronised electrical stimulation provides a measurable step on top. And the part that has changed recently is that the stimulator no longer has to arrive bolted to a new bike. For many years, we worked with the RehaMove system, which integrated an 8-channel stimulator with a version of the MOTOmed bike. We were always aware that the total cost of the system meant that many people could not adopt it. And as the stimulator needed to communicate directly by cable with the bike, we were restricted to one or two models of MOTOmed. Why should they give up the bike that they were already using and replace it with one that happened to support FES cycling?

Things have changed now with the arrival of Stim2Go. The bike you already own, whatever the make, is the awkward part of an FES cycling system, and you already have it. Let's see whether adding Stim2Go would be worth it.

When I demonstrate an FES cycling system, spasticity is usually in the room before I have finished setting up. A leg that will not settle onto the pedal. A knee that pushes out straight at the wrong moment. A foot that starts bouncing the instant it takes any weight. The person in the chair rarely calls it spasticity. They say their legs have a mind of their own, or that everything goes rigid when they transfer, or that the spasms wake them at three in the morning. The clinical word comes later, if it comes at all.

This article is for the person who has just been introduced to that word, or who has lived with the thing itself for years without anyone quite explaining it. I want to cover what spasticity and spasms actually are, why they happen after a spinal cord injury, a stroke or with multiple sclerosis, what they do to daily life, and what genuinely helps, from medication through to electrical stimulation. I will try to be clear about what the evidence shows and what it does not; if different people have told you contradictory things, that is partly because the field itself contains genuine uncertainty.

One of the quieter worries in rehabilitation is rarely about the therapy itself. It is about money. Equipment is expensive, budgets are tight, and funding is often uncertain until late in the process. The fear we hear most is not "will this work," but rather "will I spend a significant sum and end up with the wrong thing, or with several things that do not work well together." Does this sound familiar?

It is a reasonable worry, and it deserves a straight answer rather than a sales pitch. This article looks at one practical way of reducing that risk: choosing a single, flexible stimulator that covers several rehabilitation needs, rather than a separate machine for each. The device we have in mind is the Stim2Go, and the point is not so much the brand as the principle behind it.

Transcutaneous spinal cord stimulation (tSCS) has moved quickly from a research curiosity to a recognised tool in neurological rehabilitation. People living with spinal cord injury, stroke, and multiple sclerosis are asking us about it. Clinicians want to know which device to recommend. Equipment commissioners want evidence-led guidance before authorising spend that can run into tens of thousands of pounds per system.

A paper published in Nature Biomedical Engineering on 12 May 2026 has added something important to that conversation. It is not a clinical trial. It is a careful study of the physics and physiology that govern which nerve fibres a tSCS device actually recruits. The finding is consequential, and it bears directly on the choice of device.

In short: the waveform you choose determines whether tSCS does the thing rehabilitation needs it to do.

We have just recently redeveloped our sister site, fescycling.com, dedicated to functional electrical stimulation cycling: the evidence, the practicalities, and the questions that come up most often in clinic. The articles below are written for people considering FES cycling, the families and case managers supporting them, and clinicians who want a clearer view of what the technology can and cannot do.

If you are new to FES cycling, the first three are the natural starting point. The rest go deeper into specific questions, conditions, and day-to-day reality. Although our offered system is based on the Stim2Go unit from Pajunk, the articles should be of general interest to those who wish to learn more about FES cycling.
