Can I buy an electricity generating bike?

Yes, you can buy an electricity generating bike. It's called the RE:GEN, and we're now taking pre-orders for 2022 delivery. 


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 to 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 surburban 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, gyms, and businesses. 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 useable 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, and 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 then transferred and stored inside the Ohm - a portable clip-on battery unit that sits between the handlebars.

  • The Ohm is 100 wH and has 2 USB outlets. Once a user has finished a workout, he or she can then unlock the Ohm from the bike and use it to charge electronic devices. Users can also purchase an additional snap-on extender allowing 5-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 150Wh per hour of cycling. One workout is enough to charge 2.6 MacBook Pros, 4 iPad Pros, and 14 iPhones (or Android equivalent). 

  • For the commercial bike: Generate and Store up to 250W per hour of riding


So yes, you can buy an electricity-generating bike.  To find out more about the RE:GEN visit our experience page.  To pre-order your bike, head to our product ordering page.

    I think this is great idea. I also think Laura Wall is an idiot for suggesting such a thing.

    I think governments should make it a law that all gyms are fitted with these bikes and, in fact, all exercise equipment that can generate electricity.
