Quick verdict
For most people the Gadnic B18 is the best buy: upright, with a 4-function display and an adjustable seat, which is what you need to pedal steadily while watching a series. To spend the least, the Gadnic F-3050 is the entry point; and if you're serious about training, the Daewoo spin bike has a flywheel and a sporty position.
What to look for before buying
- Upright or spin — This decides everything. An upright sits you straight, comfortable for easy pedalling while watching something, and is usually cheaper. A spin bike puts you in a sporty forward-leaning position with a heavy flywheel that simulates road riding: it trains harder but is uncomfortable if your plan is an easy hour.
- Flywheel weight — It's the number that most defines the pedalling feel and the one almost nobody checks. A light flywheel makes pedalling jerky and uneven; a heavy one, 6 kg and up, gives continuous, smooth motion much closer to a real bike. On spin bikes this figure separates a good machine from one that gathers dust.
- Resistance type — Budget units use belt or felt-pad resistance rubbing against the flywheel: it works, but wears and eventually gets noisy. Magnetic resistance has no physical contact, so it's far quieter and doesn't wear. If you'll use it in a flat, early or at night, quiet stops being a luxury.
- Maximum user weight and stability — This is a safety figure, not marketing. Check the stated maximum and leave margin: a bike at the limit of its capacity flexes and feels unsafe. And look at the bike's own weight: counterintuitively, the heavier it is, the more firmly it stays put when you pedal hard.
- Adjustments and display — The seat must go up and down, and ideally forward and back too: with the height wrong, your knee will complain within three sessions. The time, speed, distance and calorie display isn't accurate — calories are a rough estimate — but it helps enormously as motivation to keep the routine going.

An exercise bike is one of the most used and most abandoned pieces of home gym equipment. The difference between the two outcomes is almost never the brand: it’s having picked the right type for how you’ll actually train.
What to look for
- Upright or spin: straight and comfortable for long sessions, or leaning and sporty for interval training.
- Flywheel: 3-5 kg is enough on an upright; 6 kg or more on a spin bike. It’s what makes pedalling smooth rather than jerky.
- Magnetic resistance: quieter and doesn’t wear. Matters in a flat.
- Adjustable seat: with the height wrong, your knee complains within three sessions.
Our pick
For most people the Gadnic B18 is the most sensible: upright, with a display and an adjustable seat. It’s the position that lets you pedal for 40 minutes watching a series, which is what people actually sustain. To start cheaply, the Gadnic F-3050; and if you’re serious, the Daewoo spin bike has the position and flywheel for hard training.
An honest warning
The display’s calorie counter isn’t a measurement, it’s an estimate from generic formulas that know neither your weight nor your real effort. It can be well off. Use it as motivation to keep going, not as data for calculating your diet.
And the advice worth most: pick the one that feels comfortable, not the sportiest. The bike that works is the one you use; the uncomfortable one becomes a clothes rack within three weeks.

Frequently asked
Upright or spin?
It depends how you'll train. An upright keeps you sitting straight, with a comfortable backrest on some models, and is ideal if your plan is 40 easy minutes while watching something. It's more comfortable to start with and for older users or those with back issues. A spin bike leans you forward, cyclist-style, with a heavy flywheel that allows intense interval sessions. It's what gym classes use. If you're starting out and your goal is to move and keep it up, the upright usually wins: the bike that gets used is the one that feels comfortable.
How heavy should the flywheel be?
For recreational use on an upright, 3 to 5 kg is enough and paying more isn't worth it. For spin, look for 6 kg minimum and ideally 8 or more: a heavy flywheel is what makes pedalling continuous rather than jerky, and what lets you train standing without the bike shaking. It's the spec with the biggest gap between a machine you'll use and one that becomes a clothes rack.
Is it good for losing weight?
It works as part of a plan, not as a magic solution. Pedalling is low-impact aerobic exercise, very kind to the knees, and sustained over time it adds real calorie expenditure. But the calorie figure on the display is a rough estimate based on generic formulas, not a measurement: it can be quite far off. What really determines the result is consistency and diet. The concrete advantage of having one at home is that it removes the weather and the trip to the gym as excuses.
