Most people understand the concept of a power-generating exercise bike; they just don't realise its potential. It's because microgeneration sounds...well, too small-scale to be useful in the modern world. Of course, that's the point. Microgeneration means small-scale energy production. It's the kind used in homes and small businesses: solar panels on a roof or small-scale wind turbines, for example. 

But one of the biggest advantages of this type of clean energy generation is that generally, it's less conspicuous and affordable; it's also relatively easy to install and maintain. 

The opposite of microgeneration would be something like a hydroelectric dam or off-shore wind farm. These are very obtrusive on the landscape, and they're expensive to build and maintain, but they do produce large volumes of clean energy. 

It's easy to argue that these two types of energy production are mutually exclusive with relatively little in common. And whilst it's true you can't put 50-wind turbines in the average suburban garden, you can, as a home or business owner, benefit from both large and small-scale energy generation. In order to decarbonise the global economy, we must generate more clean energy.  There's not enough to keep up with global demand, so why not use microgeneration more effectively, more regularly, to help support these much bigger energy projects? 

What about human power? It's clean, renewable and abundant. 

It's why Energym has developed the RE:GEN. It's a power-generating exercise bike for homes, commercial gyms, and office space. You can't power an entire house from a single bike, that's true, but if you're drawing power from the entire fitness community - those exercising at home and inside gyms - then that power adds up.

The UK has 10 million gym members. Globally, the at-home exercise equipment industry is expected to hit $31 billion by 2025. Imagine tapping into all those workouts and then capturing and converting that energy and turning it into usable electricity. 

It's the benefit of microgeneration: exploiting a form of energy generation that's already happening. Indoor bikes fitted with Energym's technology allows for power generation without the associated economic, environmental, and political impacts of larger-scale projects like nuclear plants, hydroelectric dams, solar farms, etc. Switching to an electricity-generating bike requires no behaviour change on the user's part.


How is the RE:GEN an electricity-generating bike?

  • Users exercise as they would on any other stationary bike. The magic happens in the flywheel, where a generator captures and converts human effort and turns it into clean power. This power is transferred and stored inside the Ohm - a portable clip-on battery unit that sits between the handlebars.

  • The Ohm is 100 wH. Once a user has finished a workout, he or she can unlock the Ohm from the bike and use it to charge electronic devices. Users can also purchase an additional snap-on extender allowing multiple devices to charge simultaneously.

  • During the workout, the Ohm is also a live power meter displaying functional threshold power (FTP) within a 5-colour zoning system, so users can easily see when they're exercising efficiently and at their peak. The Ohm is both WiFi and Bluetooth enabled.

  • The bike's electronics are stored in the Enerbox, which sits at the back of the bike. Its sleek design has a Lamborghini-inspired air-dissipation fin.

  • Resistance is controlled electronically via handlebar-mounted controls & an In-App manual/automated control.

  • Clean energy generation is tracked via an app. Users can see exactly how much human power they've captured during their workout.

How Much Electricity Can a Bike Generate?


  • For the at-home REGEN: Generate and Store up to 100Wh per hour of cycling. One workout is enough to charge 2.6 MacBook Pros, 4 iPad Pros, or 14 iPhones (or Android equivalent). 

  • For the commercial bike (gyms and businesses): Generate and Store up to 250W per hour of riding.


So yes, you can buy an electricity-generating bike. Find out more and pre-order yours today. 


What About Exercise Equipment That Generates Electricity? 


But Energym isn't just stopping with the RE:GEN. We're also developing electricity-generating exercise equipment for homes and gyms using the Energym app and the Ohm portable battery unit (central batteries for gyms and commercial premises). This will allow users who don't exercise using indoor bikes the opportunity to generate clean power and for gyms to maximise their energy-generating potential.

I would like the cheapest exercising bike to create energy for my home and keep fit.

Kalbir Singh Basra

That’s so cool! At 20 cents per kilowatthour it takes just around 10 000 hours of exercise to offset the cost of the battery. A definite buy!

I have been thinking about this same idea for a long time. So exciting to see you are making a go of it. I will recommend this to everyone I know. I also recommend we try to be kind to one another.

It would be nice if you showed shipping estimates, even if they’re not guaranteed. For those of us on another continent, shipping costs are a big part of the purchase decision.


I had this idea while at the gym awhile ago. Happy to see it is a thing. I think the government should make it a law that Laura Wall has to generate all of her own electricity.
