Exercise Bike Dimensions and the Space You Need
For anyone choosing where an indoor bike will go, or which type fits a small room. Dimensions of spin, upright, recumbent, air and folding bikes, with the clearance around them and how rider height affects the fit.
An indoor cycling (spin) bike or upright exercise bike takes roughly 4 × 2 ft (122 × 61 cm) of floor and stands about 4 to 5 ft (122 to 152 cm) tall. A recumbent bike is longer, about 55 to 70 in (140 to 178 cm). With 2 ft (60 cm) of clearance around it, plan on an area of about 8 × 6 ft (2.4 × 1.8 m) for a spin bike.

Exercise bike dimensions by type
The five common types differ mainly in length. Width stays close to 2 ft for all but the widest recumbents, because it is set by the pedal crank and the stabilizer feet.
| Bike type | Length | Width | Height | Weight |
|---|---|---|---|---|
| Indoor cycle / spin bike | 45-60 in (114-152 cm) | 20-31 in (51-79 cm) | 44-59 in (112-150 cm) | 90-150 lb |
| Upright bike | 35-50 in (89-127 cm) | 20-26 in (51-66 cm) | 50-60 in (127-152 cm) | 60-110 lb |
| Recumbent bike | 55-70 in (140-178 cm) | 22-30 in (56-76 cm) | 44-52 in (112-132 cm) | 70-130 lb |
| Air (fan) bike | 48-55 in (122-140 cm) | 23-26 in (58-66 cm) | 48-52 in (122-132 cm) | 65-130 lb |
| Folding (X-frame) bike | 30-35 in (76-89 cm) | 18-22 in (46-56 cm) | 45-50 in (114-127 cm) | 30-50 lb |
Published specs for popular models:
| Model | L × W × H | Metric |
|---|---|---|
| Peloton Bike | 59 × 23 × 53 in | 150 × 58 × 135 cm |
| Peloton Bike+ | 59 × 22 × 59 in | 150 × 56 × 150 cm |
| Schwinn IC4 | 54.6 × 30.7 × 51.8 in | 139 × 78 × 132 cm |
| Concept2 BikeErg (footprint) | 48 × 24 in | 122 × 61 cm |
| Assault AirBike Classic | 51 × 23.3 × 50 in | 129 × 59 × 127 cm |
| Schwinn 230 Recumbent | 64 × 27.7 × 49.9 in | 163 × 70 × 127 cm |
Two of those numbers need a note. Peloton's overall length of 59 in includes the handlebar and screen overhang, while the feet that touch the floor fit inside about 4 × 2 ft. And manufacturer widths are measured across the widest point, often the stabilizer feet or pedals at full extension, so independent measurements of the same bike can come out a few inches smaller.
Space needed around an exercise bike
A bike does not throw you backward like a treadmill, so the clearance is about access: room to swing a leg over, to reach the bike from either side, and to keep pedals and elbows off the wall. Peloton recommends at least 60 cm (2 ft) on all sides, and Concept2 specifies a 60 × 48 in (152 × 122 cm) area for the BikeErg.
| Bike | Footprint | With 2 ft (60 cm) all round |
|---|---|---|
| Folding bike | 32 × 20 in | About 6.7 × 5.7 ft (2.0 × 1.7 m) |
| Spin or upright bike | 48 × 24 in | 8 × 6 ft (2.4 × 1.8 m) |
| Air bike | 51 × 24 in | About 8.3 × 6 ft (2.5 × 1.8 m) |
| Recumbent bike | 64 × 28 in | About 9.3 × 6.3 ft (2.8 × 1.9 m) |
In a tight room you can put one long side against a wall as long as the pedals and your knee do not hit it; leave the full 2 ft on the side you mount from and behind the saddle. Air bikes need more: the fan pulls in and blows out air, and the moving arms swing about a foot forward and back, so keep the front and sides clear.
Ceiling height and standing climbs
Seated riding needs no special ceiling. Standing out of the saddle on a spin bike is different: your feet are on pedals that pass 10 to 20 in (25 to 50 cm) above the floor, so your head can rise above your normal standing height. A 6 ft 2 in rider climbing out of the saddle can reach about 7 ft 6 in. Under a 7 ft basement ceiling or a low beam, tall riders should keep climbs seated, or put the bike where the ceiling is highest.
Bike fit: rider height and adjustment range
A bike that fits the room still has to fit the rider. Check the manufacturer's rider height or inseam range before buying, especially for riders under about 5 ft 1 in or over about 6 ft 4 in. Peloton, for example, lists a range of 4 ft 11 in to 6 ft 4 in and an inseam of 25 to 36 in.
- Saddle height. A common starting point is your inseam × 0.883, measured from the center of the crank axle to the top of the saddle. A 32 in (81 cm) inseam gives about 28.3 in (72 cm). At the bottom of the stroke your knee should still be slightly bent.
- Saddle setback. With the cranks level, your front knee should be roughly over the pedal axle. Bikes with fore-aft saddle adjustment let you set this.
- Handlebar height. Start level with the saddle. Raise it if your lower back or neck complains; lower it only for a more aggressive position.
- Recumbents adjust by sliding the seat along a rail, which can add several inches to the total length at its rearmost setting. Measure the bike with the seat where a tall user would put it.
Road and mountain bike frame sizing works differently; see the bike frame size chart if you are fitting an outdoor bike to a smart trainer.
Which type suits which space
- Smallest footprint: a folding X-frame bike, which folds to roughly 20 × 20 in and stands about 4.5 ft tall. Resistance and stability are limited, and riders over about 250 lb should check the weight rating.
- Most riding for the floor area: a spin or upright bike inside 4 × 2 ft. Most have front transport wheels and can live against a wall.
- Back or joint comfort: a recumbent bike, which costs about 1.5 ft of extra length.
- Interval training: an air bike, which needs the extra clearance for the fan and moving arms.
A bike is the most compact of the cardio machines. A treadmill needs about 15 ft of free length including its safety zone, an elliptical needs a high ceiling, and a rowing machine needs a strip about 9 ft long. To lay a bike out alongside weights and other machines, see the home gym size guide.
Frequently asked questions
How much space do you need for an exercise bike?
Allow the bike's footprint plus about 2 ft (60 cm) on every side. For a typical 4 × 2 ft spin bike that is about 8 × 6 ft (2.4 × 1.8 m). A recumbent bike needs about 9.3 × 6.3 ft (2.8 × 1.9 m). Concept2 specifies 60 × 48 in (152 × 122 cm) of space for its BikeErg.
What are the dimensions of a Peloton bike?
Peloton lists the original Bike at 59 × 23 × 53 in (150 × 58 × 135 cm) overall, on a footprint of about 4 × 2 ft (120 × 60 cm). The Bike+ is about 59 × 22 × 59 in, taller because of its larger screen, on the same footprint.
How heavy is an exercise bike?
Folding bikes weigh about 30 to 50 lb (14 to 23 kg). Spin bikes are about 90 to 150 lb (41 to 68 kg), heavier with a big flywheel. Recumbent bikes are 70 to 130 lb, and air bikes such as the Assault AirBike Classic about 96 to 98 lb.
Is a recumbent bike bigger than an upright bike?
Yes, by length. A recumbent bike is about 55 to 70 in long because the seat sits behind the pedals, compared with about 35 to 50 in for an upright bike. It is lower, around 44 to 52 in, and similar in width.
