Exercise bike for a heavy person: the honest weight ratings
Choosing an exercise bike for a heavy person comes down to one number the listings tend to bury: the maximum user weight. Two of our five bikes are rated to 150 kg and two to 120 kg. Bodies vary far more than bike ratings do: 64.5% of adults in England were overweight or living with obesity in 2023 to 2024, up from 61.2% in 2015 to 2016[1] (Office for Health Improvement and Disparities), yet most bikes are still built to a single 120 kg figure. This page tells you which of ours genuinely takes your weight, and what our owner found when he rode all five at 107 kg.

What does a maximum user weight actually mean?
A maximum user weight is the heaviest rider the manufacturer has tested the bike for and will warrant it for. It is not the weight at which the frame snaps. That is the myth, and it is why the number gets treated as a dare rather than a specification.
What the rating really covers is everything that wears. A bike is not loaded once, it is loaded a few thousand times per ride: every pedal stroke puts force through the crank, the bottom bracket, the seat post and the welds. The rating is the manufacturer's statement about how those parts behave under that load, repeatedly, for the life of the warranty. Go past it and the likely result is not drama. It is flex you can feel through the frame, a seat post that works loose, bearings that grumble early, and a warranty claim that may not be honoured.
The practical advice is to leave yourself headroom rather than sitting exactly on the limit. A rating is a ceiling, not a target.
What changes between a 120 kg and a 150 kg rating?
A 150 kg bike is usually a heavier machine in every sense: thicker steel in the frame, a wider stance on the stabilisers, a stronger seat post and better bearings. You do not experience that as a number. You experience it as the bike staying still while you work.
It is not a niche concern either. 26.5% of adults in England were living with obesity in 2023 to 2024, up from 22.6% in 2015 to 2016[1] (Office for Health Improvement and Disparities). Equipment ratings have not moved with the population, and a single 120 kg default across most of the market is the result. That is a criticism of the industry, not of anyone reading this.
That is also why the higher-rated bikes in our range are the two that do not fold. Folding costs you a hinge in the middle of the frame, and a hinge is the first thing to flex. It is a genuine trade-off rather than a fault: a folding bike buys you your room back, and a fixed frame buys you stability.
Which of our exercise bikes take the most weight?
Two of them: the Studio Pro S3 indoor cycle and the ComfortGlide R500 recumbent bike, both rated to 150 kg. The FoldFit X1 and the CityRide U2 are rated to 120 kg, and the CityRide's figure is confirmed from the box rather than copied off a listing.
The DeskFit Mini is the honest gap. Its manufacturer does not publish a maximum user weight, so we do not publish one. Our owner used it at 107 kg and it was fine, but one person getting on a thing is not a rating, and we are not going to dress it up as one.
What our owner found riding all five at 107 kg
This is the part almost no page ranking for this search can tell you, because almost nobody writing them has sat on the bike. Our owner, Asif, is 107 kg and rode all five of ours. These are his own first-hand notes, not a lab test.
On the FoldFit X1 and the CityRide U2, both rated to 120 kg, he would not recommend anyone at his weight sitting on them for more than about 15 minutes at a time. He was careful to say that this is not the product's fault. Both bikes are comfortably within their rating at 107 kg and both are fine bikes. It is that a compact saddle and a lighter frame are built for shorter, more frequent rides, and at his weight that is how they are best used. If you want to sit for an hour, that is the honest limit of a 120 kg folding or upright bike.
The two 150 kg bikes were a different experience. On the Studio Pro S3 he found the seat felt like the gym and the bike stayed stable out of the saddle, which is exactly what you want when you are putting real weight through the pedals. On the ComfortGlide R500 he said he could sleep in the seat, and that you can customise everything about the riding position. If comfort over a longer ride is what you are after, that is the one.
Spin bike or recumbent for a heavier rider?
Both take 150 kg, so the rating does not decide it. How you want to sit does. A recumbent puts you in a reclined, back-supported seat with a step-through frame, so you step in rather than climb on and your weight goes through a wide seat instead of your wrists. A spin bike puts you over the pedals on a steel frame, ready to work hard.
If you want to ride longer and more comfortably, look at our recumbent exercise bikes. If you want to train hard and do not mind a firmer saddle, look at the indoor cycles. You can also see every model, and every rating, across the full range.
One thing this page deliberately does not do is talk about weight loss. You asked an equipment question and this is an equipment answer. If the other question is also on your mind, our weight loss guide covers it honestly and in its own right.

Weight rating questions, answered
What does the maximum user weight on an exercise bike mean?
It is the heaviest rider the manufacturer has tested and warranted the bike for. It is not the weight at which the frame gives way. It is the point beyond which the bearings, seat post, welds and warranty are no longer guaranteed, so treat it as a limit rather than a target.
Which exercise bike is best for a heavy person?
In our range, the Studio Pro S3 and the ComfortGlide R500. Both are rated to 150 kg, the highest we sell. The Studio Pro S3 is a studio-style indoor cycle on a steel frame; the ComfortGlide R500 is a recumbent with a back-supported, step-through seat. Choose on how you want to sit, not on the number.
Is there an exercise bike rated for 150kg?
Yes. Two of our five are rated to 150 kg: the Studio Pro S3 at £279 and the ComfortGlide R500 at £549. Both prices include VAT and free UK delivery. We do not sell a bike rated above 150 kg.
What happens if you go over the maximum user weight?
You are outside what the manufacturer tested and warranted, so a warranty claim may not be honoured. In practice you are more likely to notice flex and wobble in the frame, and faster wear on the bearings and seat post, than any sudden failure. It is worth leaving yourself headroom rather than sitting exactly on the limit.
How much weight can the DeskFit Mini take?
The manufacturer does not publish a maximum user weight for the DeskFit Mini, so we do not publish one either. We will list a figure as soon as the manufacturer confirms one, and not before.
Will an exercise bike help me lose weight?
It can, as part of a calorie deficit, but that is a different question from which bike takes your weight. Our weight loss guide covers it properly rather than in passing.
