Best Folding Exercise Bikes
Of the seven bikes read for this site, only two are listed as folding: the XTERRA FB180 at 18 x 18 x 51 inches folded, and the Marcy NS-652, whose page gives no folded size. Both are compared here from the makers' pages, read on 2026-11-02. MudderElla did not test or measure either.
What the pages say about folding
This guide sits under our wider comparison, best exercise bike for home, and covers the two bikes whose pages describe a folding frame. The other five bikes in that comparison (Schwinn IC4, Sunny SF-B1805SMART, Sole R92, Schwinn 230 and Sunny SF-RB424006) have no folded size on their pages. None of those pages describes a folding frame, so they are not treated as folding bikes in this guide, however compact. Their footprints are listed below for comparison.
Folding on a home exercise bike differs from folding on a treadmill. These are small upright bikes with a compact frame, and the saving is mostly floor area and storage height, not a flat slab. The pages show trade-offs: both list lower weight limits than the other five bikes, and the XTERRA page states a 3.1 lb flywheel.

| XTERRA FB180 | Marcy NS-652 | |

Notes on each bike
XTERRA FB180. XTERRA's page is the only one of the two that prints a folded size, 18 x 18 x 51 inches, with a set-up footprint of 31.7 x 18.1 inches, so folding takes the length from 31.7 to 18 inches and the height rises from 42.7 to 51 inches. The page states a 3.1 lb flywheel (6.18 inch diameter), a rider height range of 4'10" to 5'10", and a 250 lb limit. Two details conflict: the description says magnetic resistance, but the spec table says "Outer Brake Resistance". The price has two readings: $249.99 and $179.99. The warranty is the shortest of any bike in the hub at 1 year on the frame and 90 days on parts. Wrong for: riders taller than 5'10" or heavier than 250 lb, or anyone who wants a long warranty.
Marcy NS-652. Marcy's page shows $169.99 as both regular and current price, and on 2026-11-02 it showed the bike as unavailable, so it could not be bought from the maker that day. It lists 8 preset resistance levels, an inseam range of 28 to 33 inches, a 250 lb limit and an assembled size of 32 x 18.25 x 42.25 inches. It says it folds but gives no dimensions, so this guide cannot say what the folded footprint is. It also gives no flywheel weight, machine weight or noise statement. The 2-year limited warranty is the longer of the two. Marcy's refund policy page, which was read in full, requires calling support first for an approval number. Wrong for: a buyer who needs a folded size to plan storage, or who wants to order today.
How the pair differ
The XTERRA is the only one that tells you the folded size, and it states a taller-rider height range. The Marcy has the longer warranty, and its fit is stated as an inseam of 28 to 33 inches rather than a rider height. Both list the same 250 lb limit and 8 resistance levels. On price, the Marcy page shows $169.99 and the XTERRA $179.99 on the read date; $10 apart, with the XTERRA's price tied to a code that may or may not be required.
The other five bikes are not folders, but their pages give the footprint for comparison:
| Bike | Footprint (L x W x H, inches) | Weight limit |
|---|---|---|
| Sunny SF-B1805SMART | 50.8 x 23.4 x 47.6 | 300 lb |
| Sunny SF-RB424006 | 51.8 x 25.6 x 46.1 | 300 lb |
| Schwinn IC4 | 54.6 x 30.7 x 51.8 | 330 lb |
| Sole R92 | 56 x 29 x 60 (order not labelled) | 300 lb |
| Schwinn 230 | 64 x 27.7 x 44 | 300 lb |
The two folding bikes' set-up footprints, 31.7 and 32 inches long, are roughly 19 to 32 inches shorter than those. The trade is the limits: 250 lb, and a narrower rider range stated on each page.
Measure before you buy
- Measure the storage spot, then compare with the XTERRA's 18 x 18 x 51 inch folded figure; ask Marcy for its folded size in writing.
- Check the rider: the XTERRA lists 4'10" to 5'10" and the Marcy an inseam of 28 to 33 inches.
- Read each return policy. Marcy's states a 15% restocking fee on buyer's-remorse returns and that you pay shipping both ways; XTERRA's policy page was not read.
- Confirm the XTERRA price and any code with XTERRA before ordering.
