Best Exercise Bike Under £300 UK
£150 – £300|Updated 2026-06-17|5 products reviewed
An exercise bike is one of the most space-efficient pieces of home cardio equipment you can buy, and under £300 the UK market offers genuine quality. Whether you want a spin-style bike for intense HIIT sessions or an upright bike for steady-state cardio while watching TV, the key is matching the resistance system and flywheel weight to how you actually plan to train.
What to Look For
- 1Magnetic resistance is quieter and requires less maintenance than friction pad systems — worth prioritising if you train early mornings or in a flat
- 2Flywheel weight matters: 6-8 kg suits casual riders, 13 kg+ gives the smooth heavy feel that spin class regulars expect
- 3Check the seat adjustment range — many budget bikes only adjust height, not fore/aft position, which causes knee strain for taller riders
- 4If you want to follow Peloton or Zwift classes, ensure the bike has a tablet holder and ideally Bluetooth for heart rate monitor pairing
- 5At this price point, pedals with toe cages are standard; SPD clipless pedals usually require a £20-£30 swap which is straightforward

Editor's Note
The UK exercise bike market peaks in January and dips in May-June, so late spring is the best time to find clearance deals. JLL Fitness and Branx are UK-based with domestic warranty service, which gives them an edge over imported brands when something goes wrong. For most home users, a 13 kg magnetic flywheel hits the sweet spot between ride feel and price.
Frequently Asked Questions
Is a £300 exercise bike good enough?
For home use, absolutely. A £300 budget gets you a magnetic resistance bike with a 13-18 kg flywheel, adjustable seat, and a stable frame. You won't get a built-in screen like Peloton, but paired with a tablet and a Bluetooth heart rate monitor, the training experience is comparable.
What is better for weight loss — exercise bike or treadmill?
Both burn similar calories at moderate intensity (around 400-600 kcal per hour). Exercise bikes are lower impact on joints, quieter in flats, and take up less space. Treadmills engage more muscle groups. Choose whichever you'll actually use consistently.
How heavy should the flywheel be on a home exercise bike?
For casual fitness, 6-8 kg is adequate. For spin-style training that mimics a gym bike feel, look for 13 kg or heavier. Heavier flywheels provide smoother pedalling momentum and more realistic road feel, but the bike itself will be heavier to move.
Are spin bikes or upright bikes better for beginners?
Upright bikes with a wider seat are more comfortable for beginners doing 20-30 minute sessions. Spin bikes suit people who want intense interval training or to follow spin classes at home. If you're unsure, an upright bike is the safer starting point.
