- Indoor Bike and Spinning Bike mean the same device in everyday use: a sporty, forward-leaning riding position, a firm pedal stroke, and the option to ride out of the saddle. “Spinning” is a protected brand name (Mad Dogg Athletics), not a separate type of equipment.
- An ergometer is the upright exercise bike with a reliable watt display. It is designed for controlled, steady endurance training, not for standing sprints.
- Three things determine your purchase, not the label: riding position, type of resistance, and noise level in your living space.
- Our oak Indoor Bike home trainer uses 32 hydraulic resistance levels instead of a heavy flywheel, measures 115 x 60 cm, weighs 40 kg, and according to the datasheet reaches a maximum of 35 dB.
- The honest limitation: If you are used to the long spin-down of a heavy flywheel or train with calibrated watt values, you will notice the difference. For everyone else, it plays no role in training.

Three terms for devices that stand side by side in stores and look almost identical to the untrained eye. When searching online, you will find the same bikes described as Indoor Bikes, Spinning Bikes, and ergometers. This article explains where the difference really lies, where it is merely marketing, and which device suits which type of training.
What is the difference between an Indoor Bike, Spinning Bike, and ergometer?
The difference lies in the riding position and measurement accuracy, not in the name. Indoor Bike and Spinning Bike refer to the same device: a stationary bike with road-bike-like geometry, where your upper body leans forward and you can rise out of the saddle while pedaling. An ergometer, by contrast, is ridden upright, with your back remaining straight, and displays your performance in watts.
Why are there three terms at all? “Spinning” is a registered trademark of the US company Mad Dogg Athletics, originally used for a class concept with matching bikes. Because the concept took over every gym in the nineties, the brand name became a generic term, roughly like “Kleenex” for tissues. Manufacturers who are not allowed to use the brand therefore write Indoor Bike, Indoor Cycle, or Speedbike.
The difference with an ergometer, however, is a technical one. With an ergometer in the strict sense, the watt display is tested and deviates from the actual value only within narrow limits. With a basic exercise bike, the number on the display is an estimate based on cadence and resistance level. This difference is crucial for rehabilitation training or a watt load prescribed by a doctor. If you simply want to train your endurance and work up a sweat, you will not notice it.
Which bike is right for which type of training?
The indoor bike is suited to intense intervals and classes, while the ergometer is better for calm endurance training and rehabilitation. The table compares the three designs according to the criteria that actually matter in the living room.
| Criteria | Indoor bike / spinning bike | Upright ergometer | Recumbent ergometer |
|---|---|---|---|
| Riding position | Athletic, leaning forward, standing possible | Upright, with your weight on the saddle | Reclined, with a backrest |
| Typical training | Intervals, standing climbs, app-based classes, hill simulation | Steady sessions, heart-rate and wattage control | Long, easy sessions, rehabilitation, back-friendly training |
| Resistance | Flywheel with felt or magnetic brake; ours uses hydraulics | Usually a magnetic brake, often with wattage control | Magnetic brake |
| Watt display | Reference value for training | Tested and built to withstand heavy use | Tested and built to withstand heavy use |
| Strain on the back and wrists | Higher, as weight is placed on the hands | Low | Lowest |
| Space required | Compact, fixed footprint (ours: 115 x 60 cm) | Similarly compact | Significantly longer |
| Appearance in the living area | From studio-grade steel to solid wood, depending on the model | Usually black plastic | Usually black plastic, gives a medical impression |
| Our recommendation | For most people at home: covers easy riding and hard intervals with one device | If a doctor prescribes wattage targets or your back cannot tolerate leaning forward | For severe back problems or limited mobility |
The practical point is this: an indoor bike can do everything an ergometer can, but with a more athletic riding position. The reverse is not true. On an upright home trainer, you cannot sprint standing up because the geometry does not allow it. That is why an indoor bike is usually the more flexible device for home use, as long as you are comfortable leaning forward.
Flywheel, magnet, or hydraulics: which is better?
There is no universally better system—just three different compromises between riding feel, noise, and wear. Classic studio bikes use a heavy flywheel, often 18 to 22 kg, braked either by a felt pad or magnets. The flywheel provides the smooth, long after-run that many describe as a “real road-bike feel.”
The trade-off: Felt brakes are wear parts and get louder over time, while a bike with a 20 kg flywheel quickly weighs 50 kg or more in total. Magnetic brakes solve the wear problem, but cost more and operate with fixed levels rather than stepless resistance.
Our oak indoor cycling bike takes a third approach: Resistance is generated by a 32-level hydraulic system, without a heavy flywheel and without a brake pad that wears down. In practice, this means it is very quiet, low-maintenance and significantly lighter, weighing 40 kg instead of 50 to 60 kg. The honest disadvantage: You don’t get the inertia of a heavy flywheel. If you’re coming from a gym and are used to a long run-down, you’ll notice this during the first week. If you’re new to indoor cycling, you won’t miss it.
You may know the same logic from rowing, where water, magnetic and air resistance achieve the same training goal with a different feel. We explained this in detail in our comparison of water, magnetic and air resistance in rowing machines; the same way of thinking applies here.
How noisy is an indoor bike in a rented apartment?
An indoor bike is the least problematic cardio machine for a rented apartment because cycling creates no impact. According to the datasheet, our model reaches a maximum of 35 dB, roughly the level of a quiet room. For comparison, a Walking Pad produces around 40 to 50 dB when walking.
For the neighbours below you, however, it’s not airborne noise that matters but impact noise. And this is exactly where cycling has the advantage: Your feet never leave the pedals, so there is no step striking the ceiling. What remains are vibrations transmitted through the floor, which a floor protection mat for fitness equipment absorbs. It also protects parquet and laminate from pressure marks, as 40 kg is distributed across four small feet.
A review from a verified buyer on our product page describes what this feels like in everyday life better than any manufacturer’s specifications:
"Ordered at lunchtime on Thursday and it was already delivered on Friday morning. Quick to assemble, really easy as long as you follow the instructions. I did my first 10 km this morning. The thing is so quiet that your own breathing is louder :-) I’m genuinely thrilled after the first day, and the bike simply looks AWESOME—not cheap like some others."
Ronny, 5 stars, verified buyer
If you’re wavering between a bike and a treadmill and noise is your main concern: With a treadmill, the speed determines whether it becomes an issue. We worked this out in our Walking Pad noise check using the quiet hours specified in Swiss building regulations.
How much space does an indoor bike need?
An indoor bike needs a firm footprint of around half a square metre plus room to move. Our model measures 115 x 60 cm and is 112 to 121 cm high, depending on how high you set the handlebars. Allow around half a metre of clearance all around so you can get on and off comfortably.
The honest assessment is important: A bike is not a piece of equipment you put away after training. It has transport wheels and can be moved, but it does not disappear under the sofa like a walking pad. You make that decision when you buy it, not afterwards. That is precisely why the material of a stationary bike is not merely a matter of decoration: something that permanently stands in the living room should be pleasant to look at.
- Delivery: The package measures 108.8 x 24 x 82.5 cm. Measure your stairwell, not just your apartment door.
- Assembly: 90 percent pre-assembled, with tools and instructions included. Realistically, two people can finish it in just under half an hour.
- Moving it: Rubberised transport wheels with internal ball bearings, so you can tilt and roll the equipment when vacuuming.
If space is really tight, take a look at our comparison of fitness equipment for small apartments. It lists all our equipment side by side, including their footprint, storability and impact noise. If you are planning the entire setup at once, you will find the order of steps in our guide to setting up a home gym.
What should you look for when buying?
Pay attention to six points, in this order. Everything else is equipment that will not save the purchase if one of these points is not right.
- Adjustability. The saddle and handlebars must be at the right height; otherwise your knee or neck will hurt after 20 minutes. Our bike is designed for riders up to 220 cm tall and weighing 120 kg, and the footrests accommodate shoe sizes up to 50.
- Type of resistance. See above. Hydraulic and magnetic resistance are quiet and low-maintenance; felt brakes are wear parts.
- Noise level. In a rented apartment, the most important criterion after fit. Ask for a dB value, not the word “quiet”.
- App connectivity. Bluetooth in the display so routes and classes can be tracked. Our model works with Kinomap and Fitshow, and also includes a wireless receiver for a chest strap and an integrated tablet holder.
- Materials and appearance. Canadian oak and powder-coated aluminium look different from black plastic, and they age differently. Find out more in our article about wooden fitness equipment for the living room.
- Seating comfort. The most underrated factor. An ergonomically shaped saddle with 8 cm of padding determines whether you will still be riding in week three.
As a rough price guide without mentioning brands: Below around CHF 400, you’ll usually get lightweight bikes with a small flywheel that move around during intense intervals. Between CHF 400 and CHF 2,000 is the range where the frame, adjustability and electronics work well together. Above that, you’re paying for studio-grade technology or brand ecosystems with a subscription. Our indoor bike currently costs CHF 1,029 instead of CHF 1,599, with a two-year warranty and a 120-day return policy.
Who is an indoor bike not suitable for?
An indoor bike is not worth it if you either need a calibrated wattage target or already own a road bike. Three situations in which we honestly advise against it:
- Rehabilitation with a prescribed wattage target. In that case, you need a tested ergometer with a reliable display. An indoor bike shows wattage as a guide, not as a measured value.
- You cycle outdoors on a road bike. In that case, a smart trainer that lets you mount your own bike is the better investment. The same riding position, the same shoes, and one less machine in the living room.
- Back or wrist problems. This design puts more strain on the wrists and lower back than an upright position. If you already have symptoms, it’s worth checking with a doctor or physiotherapist before ordering.
And there’s one situation that has nothing to do with the machine itself: if you know you won’t train indoors because a screen and a wall sap your motivation, no machine in the world will help. In that case, running, cycling outdoors or joining a class is the more honest answer.
Frequently asked questions
Is an indoor bike the same as a spinning bike?
Yes, in everyday usage, both terms refer to the same type of machine. “Spinning” is a registered trademark of Mad Dogg Athletics and originally describes a class concept. Manufacturers without a licence therefore call their bikes indoor bikes, indoor cycles or speed bikes. Technical differences depend on the model, not the name.
Which is better: an indoor bike or an ergometer?
For training at home, an indoor bike is usually the better choice because it covers both easy and intensive sessions with one machine. An ergometer is the better option if you need a reliable wattage display, for example for rehabilitation or medical requirements, or if you find an upright seating position significantly more comfortable for your back.
Can I lose weight with an indoor bike?
Yes, cycling is one of the most efficient forms of endurance exercise for burning calories, but the decisive factor is your calorie balance over the course of the day. Realistically, aim for three to four sessions per week lasting 30 to 45 minutes. The calorie display is an estimate, so use it as a trend rather than an exact figure.
Is cycling easy on the joints?
Yes, because the movement is guided and there is no impact, unlike running. This makes an Indoor Bike a sensible cardio option even for people with a higher body weight. If you have existing knee or back problems, the seat height should be adjusted correctly and the exercise load discussed with a doctor.
Can I try the Bike before buying it?
Yes. Questions about pickup and test rides are among the most common calls we receive before a major purchase. Our equipment is located in our warehouse in Weesen and can be viewed and tried out by appointment. Book an appointment via the test appointment page or by phone at +41 43 508 20 26.
Do I need a chest strap for heart-rate measurement?
It is not essential, but it is more accurate than hand sensors. The display contains a wireless receiver for a chest strap, so the signal goes directly to the display and apps such as Kinomap. If you train by heart rate rather than by feel, you should plan to use the strap.
Can I pay for an Indoor Bike in installments?
Yes, paying in installments is one of the most common questions our support team receives in Switzerland for equipment in this price range. You can see which payment methods are currently available at checkout. How the options work and what they cost is explained in our overview of installment payments for fitness equipment and e-mobility in Switzerland.
Conclusion
Our conclusion: Leave the term spinning out of your purchasing decision; it says nothing about quality. Two real questions remain. First: an athletic forward-leaning position or an upright seating position? Second: do you need a verified watt display, or is an indicative value enough? Anyone who answers both questions honestly can narrow the choice down to one device in two minutes.
For most households, the Indoor Bike is the more flexible choice because it can do both: provide a quiet ride and support hard pedaling. In the end, what matters more than the last five kilos of flywheel mass is whether the equipment is quiet enough for your home, whether it fits, and whether it looks good enough to be allowed to stay out.
You can find all dimensions, resistance levels and the current price on the product page for the Oak Wood Indoor Bike Home Trainer.
