There are plenty of exercise bikes under £100 to choose from, but which one is the best? At this price point, the most important thing is finding a bike that's well-made and strong enough to last, rather than one that breaks after a few months of use.
We've done the legwork and compared a range of sub-£100 exercise bikes to see which comes out on top for features, sturdiness, comfort and overall quality. Here are our top picks, and every one was checked as genuinely in stock and under £100 at the time of writing.
The Ultrasport F-Bike is, without doubt, the best exercise bike you can buy for less than £100. It replaces the SONGMICS bike we used to recommend here, which is no longer sold, and it is a stronger pick anyway: Ultrasport call it Europe's best-selling F-bike, the brand has been going since 2008 and has sold over 5 million products, and the bike is TUV and GS certified. At this price, that kind of track record is worth more than a long spec sheet.
This home exercise bike has a large LCD display that shows live metrics as you train, including speed, distance, time, calories burned and your pulse, read through hand sensors built into the handlebars.
It's also impressively quiet. The magnetic resistance system is maintenance-free and gives smooth, quiet pedal movements, so there's no need to worry about waking up family or neighbours.
Resistance is one of the most important areas at any price, and the F-Bike delivers with 8 levels of magnetic resistance set on an adjustment knob you can turn while you're still riding, which is genuinely handy for intervals. Packing in 8 levels (and magnetic resistance at that) for under £95 is impressive.
The fit is better than you'd expect too. The saddle is extra-wide, cushioned and height-adjustable, and the high handlebar puts you in an upright position that's kinder to your back and knees. The reinforced double-rail frame and adjustable anti-slip feet keep it planted, and it takes riders up to 285lb (about 129kg), which is a lot of headroom for a sub-£100 bike. When you're done, the quick-folding mechanism packs it away into a cupboard or a corner, and Ultrasport reckon on a 10 minute assembly out of the box.
Why magnetic resistance matters
Magnetic resistance gives a smoother pedal feel and lasts longer than the friction systems found on most sub-£100 bikes, which is a big part of why the F-Bike takes the top spot.
If you're looking for the best exercise bike under £100, the Ultrasport F-Bike is the one to get.

Our runner-up is the vannect folding exercise bike. On paper it actually out-specs our top pick, and at £99.99 it only just squeezes under the limit, so it is worth a serious look.
The headline is 16 levels of magnetic resistance rather than 8, driven by four magnets and an aluminium rim flywheel, so there is more room to progress as you get fitter. vannect also claim a thicker 4mm steel frame against the 1.5mm used on many folding bikes, and they rate it to 330lb (about 150kg), which is more headroom than the Ultrasport and the highest limit of any bike in this guide. The seat is large and wide with 8 height settings, suiting riders from 140cm to 185cm, and the LCD covers time, speed, distance, calories and heart rate. There's a phone holder so you can watch something while you ride, it arrives 90 percent assembled, and vannect back it with 5 years of free parts replacement.
So why isn't it first? Brand track record. At this price the thing most likely to go wrong is the bike simply not lasting, and Ultrasport has been at it since 2008, with TUV and GS certification and Europe-wide sales behind it, while vannect is an Amazon-native brand with a much shorter record to judge. The specs are better, the certainty is not.
Our suggestion: take the vannect if you want more resistance levels, a higher weight limit or a phone holder, and take the Ultrasport if you'd rather buy the safer name.

If you're after something a little different, it's worth considering a mini exercise bike. A mini bike does the same job as a regular exercise bike but without the seat or handlebars. You just get the pedal section, so you can place it wherever you like and store it without the hassle of a full-sized machine.
Mini exercise bikes are great if you're short on space, or if you simply want something simple that still gives you the benefits of a regular bike. They're also significantly cheaper than upright exercise bikes.
The best mini exercise bike is the Ultrasport Mini Bike Exercise Bike. It's ultra-compact, very well built and offers variable resistance levels. More importantly, it can be used as a regular bike for your legs, or placed on a raised surface such as a table to work out your arms.
It's a great option for anyone who wants to save space or doesn't want to spend too much. It's also ideal for elderly users and anyone recovering from an injury.
