The at-home fitness industry is booming. It’s never been easier or more affordable to pursue an active lifestyle, especially if you’re hoping to avoid gym membership fees. And the range of at-home equipment is huge. Great news for those in the market for a new exercise bike, rowing machine or treadmill, but the sheer amount of choice can be overwhelming, especially for fitness first-timers or anyone looking to ramp up their exercise routine.  

One thing you’ll notice right away is the price difference between the various makes and models. You can expect to pay anywhere from £100 for a basic stationary bike to upwards of £2000 for a more advanced indoor cycling bike. One reason for the higher cost at the premium end of the scale is the rise of more technically and technologically advanced bikes. These smart bikes provide a more efficient and effective means of exercising and training and are popular with athletes, dedicated cyclists and fitness enthusiasts.   

Of course, you'll still find plenty to pick from at the budget end of the market too. 

Shopping for exercise equipment is always going to be subjective. There’s no universal right answer applicable to everyone. Picking the right indoor bike means weighing up several factors including individual budget, current fitness level and future performance goals. You may also have to factor in the amount of space available in your home to position the bike near an electrical socket if there's a screen or by a TV or window. There are also different types of stationary bike to pick from – indoor cycling, upright, recumbent and air bike.


Roger Black Exercise Bike Vs RE:GEN

In today’s post we’re comparing two popular bikes in the Roger Black range with Energym’s electricity-generating RE:GEN. Both represent value for money, albeit at opposite ends of the market.

The Roger Black folding bike is the brand’s best-selling product and is designed for easy storage while the Roger Black Gold bike is a standard but affordable upright exercise bike with an LCD display screen. The RE:GEN is a smart indoor cycling bike that captures and converts human power and turns it into useable electricity.

  • The Roger Black brand has a reputation for quality and affordability. 15 years of testimonials attest to the fact its equipment is ‘beginner-friendly’ and suitable for those in older age brackets or those recovering from illness or injury. Don’t assume that the Gold Bike won’t give users an intense workout though, because it can.  

  • The RE:GEN is also beginner friendly but is designed to withstand high-intensity sessions like indoor cycling classes and virtual races on Zwift. It’s a good place to start if you want to ramp up your calorie burn in high-intensity sessions. 

  • Flywheel weight is on the biggest differences between the bikes. The flywheel is the weighted disc at the front that rotates as the rider pedals. The Roger Black foldable bike has a flywheel of 3kg, and the gold bike has one that’s 6kg. Compare both of these to the RE:GEN’s much heavier 15kg flywheelNot everyone is bothered by flywheel weight, but it’s still important to understand why it can make a difference to your riding experience. Heavier flywheels need more effort to get moving but once there’s enough momentum it builds a smoother and more comfortable ride. This may not be noticeable if you’re riding at a regular pace, but if you’re planning on taking an indoor cycling class or pedalling at higher speeds, then you’re going to get uncomfortable and will probably start feeling unstable on the bike fairly quickly.

  • That’s not to say that you won’t get a workout in with the folding bike. It still has 8 levels of tension which will create enough resistance to get the heart rate up. The Gold Bike has 16 levels of resistance which will help ensure a varied riding routine with room for progression once you build your cardiovascular stamina. Workouts on these bikes can also be combined with other forms of exercise like walking, swimming or running. 

  • The RE:GEN has digital resistance. This means that the bike’s artificial intelligence or one of the app’s on-demand instructors can change the difficulty level without the rider having to do it manually. What’s particularly useful is that the artificial intelligence can change resistance to align a rider’s current effort with their pre-set fitness targets. This helps take the guesswork out of progression and keeps the rider on track to hit milestones and goals.  

  • Of course, one of the biggest differences between the Roger Black bikes and the RE:GEN is that the RE:GEN generates electricity. It captures and converts human power and stores it inside a portable battery unit that locks onto the bike. Riders can then use this to power their electronic devices like phones, tablets, laptops, etc.   

  • The RE:GEN is also a smart bike. It uses software to monitor a rider’s performance and progress, helping build out training plans and making exercise more energy and time efficient. 

    But it depends on the level of feedback and planning you want. All three bikes can display performance information, albeit to differing degrees. The RE:GEN pairs with the Energym app for performance monitoring, but it also has an FTP meter built into the Ohm battery. Functional Threshold Power or FTP can be a little complicated to explain. It’s beyond the scope of this article, but ultimately it’s a measurement of a rider’s best physical effort over 60 minutes. It’s a common cycling metric. Once you’ve calculated your FTP, the RE:GEN will colour-code your performance: red, you’ll need to work harder; amber you’re doing average and green, you’re hitting your stride! FTP is important if you're planning on training online or joining rides and races on Zwift and other indoor cycling apps.

  • The Roger Black bikes aren’t smart, but not everyone wants or needs access to in-depth performance metrics. You’ll find basic monitoring on the folding bike, including measurements for time, speed, distance, pulse, and calories via an easy-to-navigate display on the front of the bike.

  • The Gold bike has an LCD monitor offering both manual and programmed workouts. One of the cool features is that the bike’s computer will adjust the resistance to keep you within your set training target. The pulse monitors on the handlebars are a great way to track performance, even if you’re not too concerned about monitoring progress initially. 
  • Neither the folding bike nor the RE:GEN are mains powered. This means you don’t need to position them near to an electrical socket. The folding bike’s display runs on batteries, and the RE:GEN generates electricity rather than uses it. The Gold bike has an LCD monitor that runs off the mains, so this may influence where inside your house you put it.

  • The folding bike isn't especially attractive, but it is convenient to store in small spaces and use in high-traffic areas of your home as it's easy to put away. That’s not specific to this brand, however, as most folding bikes are basic and are designed to be functional rather than win any design awards.  

    The Gold bike is better, but again, it’s the functionality that matters. It’s what the bike can do rather than what it looks like. Premium bikes will often have a sharper and more appealing physical appearance, and that may tempt you into paying more.

  •  One area where the Roger Black bikes have a clear advantage is that they’re available to buy right now. You can go onto the Roger Black website and get one shipped immediately. The RE:GEN is currently only available for pre-order for delivery Q2 2023 delivery.  

  • The RE:GEN also costs more. This is reflected in what it can do: clean energy generation, software, FTP, app compatibility and design, etc. Indoor cycling bikes are often more expensive than exercise bikes because they can do more and are designed for higher intensities. But obviously, not everyone has the disposable income to spend on a premium smart bike.

  • The lighter flywheel isn’t ideal for high intensity classes  
  • It's not Zwift-compatible
