A smart exercise bike connects to an app or a built-in screen so you can join live and on-demand classes, ride virtual routes and track every session, all from home. It is the format that made Peloton famous, but you no longer have to buy a Peloton to get it. UK shoppers now have a wide choice of app-connected and screen-equipped bikes that cover everything from instructor-led spin classes to Zwift races, often for a fraction of the price.
This guide covers the best smart exercise bikes you can buy in the UK right now, ranked and split by what matters most: a built-in touchscreen, open app compatibility, or low cost. We have picked five options across the full price range, from a sub-£500 budget bike to a screen-equipped Peloton rival, so you can match the bike to how you actually plan to train.
How we chose
We researched the most popular and best-reviewed smart exercise bikes on Amazon UK, then cross-checked specifications against manufacturer pages and current expert reviews, plus feedback from owners. We have not physically tested every bike here ourselves, so treat this as a researched buying guide rather than a hands-on test. Prices and membership costs are correct at the time of writing and change often, so always confirm the current figures before you buy.

The Echelon EX-5s is our pick for the best smart exercise bike in the UK because it gives you the full screen-and-classes experience that most people picture when they think of a Peloton, but at a lower price. It has a 21.5 inch HD touchscreen that swivels 180 degrees so you can follow off-bike strength, yoga or stretching sessions, 32 levels of quiet magnetic resistance and SPD-compatible pedals.
The screen runs Echelon's own app, which offers live and on-demand spin classes, scenic ride videos and leaderboards. Reviewers rate the hardware highly and call it a genuine Peloton alternative, though most agree the class production and instructor roster are not quite at Peloton's level, and the full library needs a paid membership. The bike works as an ordinary magnetic bike without a subscription, but you lose most of the smart features, so factor the monthly cost into your budget.

The YESOUL S3 (the Xiaomi-backed connected version) is a compact, smart spin bike that skips the built-in screen and instead pairs with your phone or tablet over Bluetooth. It has a silent belt drive, 100 levels of magnetic resistance and works with the free YESOUL Fitness app for classes and performance tracking, including distance, speed, cadence, calories and heart rate. It is one of the more popular bikes in its class on Amazon UK and holds an owner rating above four stars.
It suits anyone who wants a tidy, quiet, app-connected bike without paying for a screen they may not use. The main downside is that third-party app support can be hit and miss: some owners report that connecting to Zwift or Kinomap does not always work as smoothly as the listing suggests, so if those apps are essential to you, double check current compatibility first.

The JLL IC400 Pro is a sturdy studio-style bike from a well-known UK brand, and it is our pick if open app compatibility matters more than a fancy screen. It has a heavy 22kg flywheel for a smooth, road-like feel, smooth magnetic resistance, a direct belt drive that stays quiet, an LCD console and a maximum user weight of 150kg. The console pairs over Bluetooth with the free iConsole+ app, and with a little setup it also works with Zwift, Kinomap and the Peloton app.
It is a great choice for keen riders who want to mount a tablet, ride virtual routes and have a bike that feels solid under heavy efforts. The honest downside is that there is no built-in screen and you bring your own device, plus the third-party apps can need some fiddling to pair, so it is less plug-and-play than a bike like the Echelon.

The Echelon EX5 is the screen-free version of our top pick, and it is a smart way to get into Echelon's class ecosystem for hundreds of pounds less. You get the same 32 levels of magnetic resistance and the same solid, four-point steel frame, but instead of a fixed touchscreen you dock your own tablet on the handlebar mount or mirror workouts to a smart TV. It connects over Bluetooth and runs the Echelon app for live and on-demand classes.
This is the bike to pick if you like the idea of guided Echelon classes but already own a decent tablet and do not want to pay for an integrated display. The catch is the same as with any class bike: the experience really depends on a paid membership, and you will need to supply and charge your own device for every ride.

If you want a smart bike for the lowest sensible price, the JOROTO X2 Pro is our budget pick. It is a no-nonsense spin bike with an 18kg flywheel, quiet magnetic resistance, a belt drive and a 160kg weight capacity, and the Pro model adds FTMS Bluetooth so it can broadcast cadence and resistance data to apps like Zwift, Kinomap and the Peloton app. That makes it one of the cheapest ways to get a genuinely app-connected ride.
It suits new riders and anyone on a tight budget who still wants the option of virtual classes through a tablet. The trade-offs are what you would expect at this price: a basic LCD monitor rather than any kind of screen, simpler adjustability than the pricier bikes, and you will want to confirm the app pairing works for your chosen platform before relying on it.
Check price on AmazonThe right smart bike comes down to whether you want a built-in screen or you are happy to use your own tablet. Here is the quick summary:
Whichever you choose, remember that the smart features are only worth paying for if the classes or virtual routes will actually get you on the bike. If they will, a smart bike is one of the easiest ways to keep a home cardio habit going.
Our top pick is the Echelon EX-5s Connect Bike. It pairs a built-in 21.5 inch HD touchscreen with 32 levels of quiet magnetic resistance and Echelon's live and on-demand classes, so it comes closest to the Peloton experience for less money than a Peloton Bike+.
The Echelon EX-5s is the closest like-for-like alternative thanks to its built-in screen and class library. If you would rather not pay for a screen, the YESOUL S3 or JLL IC400 Pro let you stream the Peloton app, Zwift or Kinomap on your own tablet for a lot less.
Only if you want the guided classes. Bikes with a built-in screen, like the Echelon EX-5s, need a paid membership to unlock the full class library, though they still work as a normal bike without it. App-compatible bikes such as the JLL IC400 Pro work for free with the manufacturer app, and you only pay if you add Peloton, Zwift or Kinomap.
Often yes, but check before you buy. Bikes with FTMS Bluetooth, like the JOROTO X2 Pro and JLL IC400 Pro, broadcast cadence and resistance data that Zwift, Kinomap and the Peloton app can read. Some budget bikes only track speed and cadence, which limits how much the apps can do.
If guided classes or virtual routes keep you motivated, yes. The interactivity is what gets most people to actually use the bike. If you just want to pedal while watching TV, a standard bike with a tablet holder will save you money.
