Best Folding Exercise Bike UK: 5 Top Picks for 2026

A folding exercise bike is the easiest way to get regular cardio at home when you do not have a spare room for gym kit. These bikes give you a proper seated ride with adjustable magnetic resistance, then fold roughly in half and roll into a cupboard or corner when you are done. They suit flats, spare bedrooms and shared spaces, and they are usually much cheaper than a full size spin bike.

We have pulled together the best folding exercise bikes you can buy in the UK right now, covering uprights, a comfy recumbent and a tiny mini bike for the smallest budgets. Whether you searched for a foldable, fold up, fold away or mini exercise bike, there is a pick here for you. Here are our five, ranked.

1. Ultrasport F-Bike Folding Exercise Bike: Best Overall

The Ultrasport F-Bike is our top folding exercise bike for the UK, and it is one of the best-selling foldable bikes in Europe for good reason. It pairs a quiet magnetic resistance system with 8 levels you can change on the move via a turn knob, an LCD display covering speed, time, distance, calories and pulse, and a padded, height-adjustable seat. It folds down quickly for storage and weighs around 18kg, so it is easy to wheel out of the way.

It suits beginners and casual riders who want steady cardio without spending much. The main downsides are the small flywheel, which makes it better for light to moderate sessions than hard sprints, and a basic display, so do not expect connected app features at this price. Maximum user weight is listed at around 110kg.

2. XTERRA Fitness FB150 Folding Exercise Bike: Best Compact

The XTERRA FB150 is the one to get if floor space is really tight. It uses a solid X-frame design that folds to around 46cm by 46cm and rolls away on built-in wheels, and it is one of the most reviewed folding bikes on Amazon UK. You get 8 levels of magnetic resistance, a silent belt drive, hand pulse sensors and an LCD window showing speed, distance, time, calories and pulse.

It is a great fit for smaller homes and shorter riders, and owners praise how quiet and smooth it is. The honest caveats are a maximum user weight of around 102kg and a compact frame that taller riders may find cramped, plus the usual budget-display quirk where distance and calorie figures are rough estimates rather than precise readings.

3. VRAi Fitness SmartXBike Pro: Best for App Workouts

The SmartXBike Pro is the pick if you want guided rides rather than just pedalling in silence. It replaces the Bluefin Tour Lite we used to recommend here, which is no longer sold, and it is a clear upgrade on it. It works with Kinomap, which adds scenic routes, structured workouts and coaching through your phone or tablet, and it also handles BitGym and VZfit for VR headsets, syncing your sessions to Apple Health or Google Fit.

Its party trick is auto resistance. On Kinomap and BitGym the bike adjusts itself to match the trainer's cues or the gradient of the route you are riding, so a climb actually feels like a climb without you touching the dial. That is driven by a permanent magnet brushless servo motor giving 10 auto-adjusting digital levels, and it is genuinely quiet with it. Very few folding bikes at any price do this.

The frame is reinforced steel with extended stabilisers, rated to 140kg, which is more headroom than any other folding bike here, and it suits riders from 150cm (4ft 11in) up to 194cm (6ft 3in). It is a 3-in-1 design, so you can ride it upright, semi-recumbent or recumbent with the adjustable back support, and it folds away like the rest. There is an LCD for time, distance, calories and pulse with hand sensors, a large iPad holder, a premium airflow saddle, and the strap pedals can be swapped for toe cages or SPDs.

It suits anyone who wants a bit more structure and a sturdier frame than the cheapest bikes offer. The honest downsides: VRAi don't publish a flywheel weight, 10 resistance levels is fewer than some rivals here manage, and VRAi themselves advise against standing up to ride it, so it is still a light to moderate cardio machine rather than a spin bike replacement.

4. JLL RE100 Recumbent Exercise Bike: Best for Comfort

The JLL RE100 is a recumbent folding bike, which means you sit back in a supportive seat with the pedals out in front rather than below you. That position takes pressure off your lower back, neck and joints, so it is a strong choice if you are returning from injury, have back trouble or simply want a relaxed ride. It has a 5kg two-way flywheel with 8 magnetic resistance levels, 6 seat positions and a monitor showing speed, distance, time, odometer, calories and pulse. The end caps double as transport wheels.

It is ideal for older users and anyone who finds an upright seat uncomfortable. The honest downsides are that a recumbent takes up more room than a slim upright even when stored, the maximum user weight is 100kg, and owners note the assembly instructions are brief and could be clearer.

5. himaly Mini Exercise Bike: Best Budget

If you want the cheapest and most portable option, a mini exercise bike like the himaly is hard to beat. It is just the pedal unit with no seat, so you use it sitting on your own chair or sofa, or tuck it under a desk to pedal while you work. It has a resistance knob to vary the effort and an LCD display showing time, count, calories and distance, and it stores in a wardrobe or a drawer when you are done. You can also use it for your arms by placing it on a table.

It suits anyone on a tight budget, people rehabbing a knee or hip, and desk workers who want to keep moving through the day. The trade-offs are obvious: there is no real saddle or proper riding position, the resistance ceiling is low, and some owners report the pedals can work loose over time, so check they are tightened before each session.

Which folding exercise bike should you buy?

We looked at the most popular and best-reviewed foldable bikes in the UK and picked these five for their features, build and value. Here is the quick summary:

• Best overall: the Ultrasport F-Bike is the all-rounder. Quiet, well priced, easy to fold and a safe first folding bike for most people.
• Best compact: the XTERRA FB150 folds the smallest and suits the tightest spaces and shorter riders.
• Best for app workouts: the VRAi SmartXBike Pro adds Kinomap guided rides with auto resistance and a sturdier 140kg frame.
• Best for comfort: the JLL RE100 recumbent is kindest to your back and joints.
• Best budget: the himaly mini exercise bike is the cheapest, smallest way to keep pedalling, and it slips under a desk.

Folding bikes are built for light to moderate cardio, so if you want heavier resistance for hard interval training you may prefer a full size machine.
