Looking for the best exercise bikes under £100? We review 7 ultra-budget options, cheap, cheerful, and realistic about what you actually get for the price.
Cheap, Cheerful, and Very Budget Aware
Let’s get one thing clear early, exercise bikes under £100 are not miracle machines. They are not spin studio replacements, they are not whisper-quiet engineering marvels, and they are definitely not built for Olympic training. What they are, however, is affordable, accessible, and often good enough to get people moving, which frankly counts for a lot.
All the exercise bikes featured in this guide were under £100 at the time of our review, and that price point is exactly why they are here. Some are basic. Some are surprisingly usable. Some come with marketing claims that should be taken with a healthy pinch of salt. But for the right person, they absolutely have a place.
For Those Chasing the Lowest Possible Price
If your priority is simple, spend as little as humanly possible and still pedal indoors, you are in the right place. These bikes are often compact, lightweight, and designed for casual use rather than daily punishment.
Cheap and Cheerful, Not High Performance
At this end of the market, “fitness bike” usually means light resistance, simple displays, and modest build quality. You might see claims about full-body workouts or advanced training, just remember, this is budget fitness, not a gym-grade experience.
Not for Everyone, and That’s Okay
Heavier users, taller riders, or anyone planning intense daily sessions may want to look higher up the price ladder. These bikes suit beginners, casual users, recovery sessions, or anyone testing the waters without committing serious money.
Why They Still Make Sense
Because movement matters. If a £90 bike helps you cycle while watching TV, rehab an injury, or start building a habit, it has done its job. Let’s get into the best of the bargain bunch.
Best 7 Exercise Bikes Under £100
#1, MERACH Folding Exercise Bike
The MERACH Folding Exercise Bike is one of those budget options that tries to look a little more premium than its price tag suggests, and to be fair, it mostly gets away with it. For under £100, you are getting a foldable magnetic bike with multiple resistance levels, a basic LCD screen, and a surprisingly tidy overall design.
The standout feature here is the 16-level magnetic resistance system. On paper, that sounds impressive for the money, and in practice it does offer a decent range for gentle cardio, rehab work, and beginner fitness. Just keep expectations realistic, the higher levels add resistance, but this is not spin-class heavy. It is smooth, quiet, and neighbour-friendly, which is exactly what most buyers at this price point actually want.
Being foldable makes it a good option for flats or smaller homes, and the adjustable seat helps it fit a reasonable range of users, though taller riders may feel a bit cramped. The LCD monitor covers the basics, time, speed, distance, and calories, and the phone holder is a nice touch, even if the screen itself is fairly simple.
Build quality is respectable rather than bulletproof. It feels stable enough for steady use, but this is not a bike you want to attack aggressively every day. Think light to moderate sessions, a few times a week. Ideal for Beginners, quiet home workouts, small spaces, and anyone wanting a tidy, modern-looking bike on a strict budget.
#2, Opti Folding Magnetic Exercise Bike
The Opti Folding Magnetic Exercise Bike is about as no-nonsense as budget fitness equipment gets. It does not try to oversell itself, and honestly, that works in its favour. This is a basic folding exercise bike designed to do one thing, get you pedalling indoors without costing much money.
Resistance is handled by a simple magnetic system with manual tension control. It is not advanced, but it is functional. You can make it harder or easier quickly, and for casual cardio sessions, that is usually enough. The 1.6kg flywheel tells you everything you need to know, this bike is for light workouts, warm-ups, and gentle calorie burning rather than intense training.
The console displays the usual stats, time, distance, speed, calories, and pulse via hand grip sensors. As with most budget bikes, heart rate readings should be taken as a rough guide rather than gospel. The display does the job, but it is very much entry-level.
On the plus side, it folds away neatly, weighs very little, and is easy to move around. Assembly is straightforward, though batteries are not included, which is worth noting. The maximum user weight of 100kg is also something to be mindful of.
This bike suits shorter sessions and occasional use best. Push it too hard or too often, and its limitations show quickly. Best for absolute beginners, light cardio, tight budgets, and anyone who wants a simple bike they can fold away and forget about.
#3, Dskeuzeew Foldable Exercise Bike
The Dskeuzeew Foldable Exercise Bike is a classic example of a budget product that promises a lot on the box. “4-in-1 whole body workout” sounds ambitious for under £100, so let’s ground expectations before we start pedalling. That said, for the money, it does offer a fair bit of flexibility compared to simpler folding bikes.
The big selling point is the upright and semi-recumbent riding positions, which allow you to switch between a more intense upright pedal and a gentler, back-supported ride. For beginners, rehab users, or anyone easing back into exercise, this versatility is genuinely useful. The included resistance bands add a bit of upper-body movement, although they are more “light toning” than serious strength work.
Resistance comes via a 16-level magnetic system, which is impressive on paper. In reality, the lower and mid levels are the most usable. The top end adds challenge, but it still remains cardio-focused rather than strength-heavy. The ride itself is smooth and quiet, making it well suited to shared homes.
Build quality is better than expected for the price, with a sturdy X-frame design and a high quoted weight capacity. The LCD screen covers all the basics and does the job without fuss.
This is not a performance bike, but it is a flexible, low-impact option for varied home workouts. Best for beginners, light full-body sessions, joint-friendly exercise, and anyone wanting more riding options without spending more.
#4, Ultrasport F-Bike Folding Exercise Bike
The Ultrasport F-Bike is something of a budget fitness veteran. It has been around for years, and that longevity is actually reassuring. This is not a flashy bike, but it is a well-proven one, and sometimes that matters more than bold marketing claims.
Comfort is where this bike really shines. The wide padded seat, upright handlebars, and relaxed riding position make it one of the more comfortable folding bikes in this price range. If you are planning longer, steady sessions rather than short bursts, this setup is far kinder on the back and knees than many cheaper alternatives.
Resistance is adjustable across 8 magnetic levels, which is fewer than some rivals, but perfectly adequate for gentle cardio, daily movement, and calorie burning. This is not a bike for high-intensity workouts, but it was never pretending to be one.
The bike folds down neatly, runs quietly, and feels stable thanks to its reinforced frame. Assembly is quick, and overall build quality feels slightly more refined than many newer budget brands. It is simple, reliable, and comfortable, which is often exactly what people want at this price. Ideal for comfortable cardio, steady daily use, beginners, and anyone who values proven reliability over gimmicks.
#5, Vannect Upgraded Folding Exercise Bike
The Vannect Folding Exercise Bike is one of those products where the marketing does a lot of heavy lifting. Phrases like “super powerful” and “premium grade” should definitely be taken with a pinch of salt at this price point, but once you get past the enthusiasm, there is a genuinely solid budget bike underneath.
Its standout feature is the 16-level magnetic resistance, which gives more flexibility than many cheaper folding bikes that stop at eight. In real-world use, this means you can progress gradually rather than jumping from “too easy” to “too hard”. It is still not a spin bike, but for steady cardio, light intervals, and daily movement, it performs well.
Comfort is another strong point. The larger padded seat is noticeably more forgiving than the narrow saddles found on ultra-cheap models. For longer sessions or casual riders, this makes a real difference. The adjustable seat height also helps accommodate a wider range of users.
The frame feels stable for a folding design, and the quoted weight capacity is reassuring, although, as always with budget equipment, smooth pedalling matters more than standing efforts. The LCD display covers the basics and does the job without fuss, while the bike runs quietly enough for evening use. This is a good choice if you want maximum features for minimal money, as long as expectations stay realistic. Best for budget buyers wanting more resistance levels, comfortable seating, and quiet daily cardio without spending more.
#6, ATIVAFIT Folding Exercise Bike
The ATIVAFIT Folding Exercise Bike sits firmly in the “cheap and cheerful” category, and it does not pretend to be anything else. This is a simple, no-frills folding bike designed for light cardio, gentle movement, and consistency rather than performance.
It uses an X-frame folding design, which helps with stability while keeping storage easy. Once folded, it takes up very little space, making it a sensible option for flats or shared homes. Transport wheels are included, which makes moving it around painless.
Resistance is handled via 8 magnetic levels, which is fairly standard at this price. These levels are best suited to beginners, rehab users, or anyone looking to keep active rather than chase fitness milestones. If you are expecting high resistance or standing climbs, this is not the right bike.
Comfort is decent for short to medium sessions. The padded seat is wide enough, and the adjustable height allows it to suit a range of users. The onboard monitor tracks the usual metrics, time, speed, distance, calories, and heart rate, but accuracy should be viewed as approximate guidance rather than scientific truth. This bike works best when used often and gently. It is not exciting, but it is functional, affordable, and accessible.
#7, Sportneer 4-in-1 Folding Exercise Bike
The Sportneer 4-in-1 Folding Exercise Bike is one of the more versatile options in the under £100 bracket, at least on paper. It combines a folding bike, semi-recumbent seating, arm resistance bands, and a basic tracking console, which makes it appealing for buyers who want “a bit of everything” without spending much at all.
The 16-level magnetic resistance is a welcome upgrade over many budget rivals and allows for smoother progression. That said, higher resistance levels still favour seated spinning rather than aggressive standing efforts. This is cardio-focused, not strength-focused equipment.
Comfort is a strong point. The padded seat with backrest makes it friendlier for longer sessions, beginners, or anyone prioritising joint comfort over intensity. The foldable design works well for small homes, and it stores neatly once collapsed.
The LCD display covers essentials like time, speed, distance, calories, and pulse, but accuracy should be treated as guidance, not gospel. The resistance bands add some upper-body engagement, although they are best viewed as light toning tools rather than serious strength training.
Overall, this bike delivers good versatility for the price, as long as expectations are realistic. Best for beginners, light full-body movement, home users with limited space. Not for Intense cyclists, heavy resistance training, or performance-focused riders.
Conclusion - Which one Should you Actually Buy?
Let’s be honest, no exercise bike under £100 is going to replace a gym bike or spin studio. That is not what these are for. What they do offer is accessibility, affordability, and the ability to move more at home without spending a small fortune.
If your goal is the absolute lowest price and basic cardio, the ATIVAFIT and Opti models do the job without fuss. They are simple, foldable, and ideal for short daily sessions.
If you want better comfort and smoother resistance, the MERACH and Ultrasport bikes stand out, especially for quieter operation and longer seated workouts.
For buyers chasing maximum features on a tight budget, the Vannect and Sportneer bikes offer more resistance levels, better padding, and added extras, just remember the marketing is louder than the actual performance.
Final Word
These bikes are best suited to beginners, casual users, rehab, weight management, and people trying to build a habit. They are not ideal for advanced cyclists, HIIT purists, or anyone expecting gym-level resistance. Used consistently, even the cheapest bike here can improve fitness. The real value is not the bike itself, it is how often you sit on it.
