The Sunny SF-RW5515 is the easier model to evaluate from published specifications: Sunny lists eight resistance levels, a 250 lb maximum user weight, and assembled and folded dimensions. The SF-RW5801 manual confirms adjustable magnetic resistance and vertical rail storage, but does not establish a numbered resistance range, weight limit, or comparable footprint. Choose based on confirmed fit and the specifications you can verify—not unconfirmed claims about the 5801.

Which model is the better fit?
Choose the SF-RW5515 if you need specifications you can plan around
The 5515 is the more straightforward choice when your decision depends on a stated capacity, exact storage clearance, or a defined resistance-level count. Its folded dimensions are particularly useful if the rower must fit into a specific closet or room. Check your available space against all three measurements: 43.3 in long, 18.9 in wide, and 52.4 in high when folded.
Consider the SF-RW5801 if its documented features meet your needs
The 5801 manual confirms knob-based resistance adjustment, a vertically folding sliding rail, front wheels, and a monitor that includes distance and RPM. Those are useful documented features, but the manual does not provide the weight limit, full dimensions, or a numerical resistance range needed for a complete specification match. Ask Sunny to confirm any of those details that matter to your purchase before ordering.

Resistance and monitor differences
Sunny lists eight resistance levels for the SF-RW5515. For the SF-RW5801, the manual says to “Rotate the Tension Control Knob (No. 45) clockwise to increase the level of resistance.” This establishes that resistance adjusts by knob, not how many distinct settings are available. Do not treat an unverified level count as a manufacturer-confirmed specification.
The monitors also have different documented readouts. Both sources include time, count, calories, total count, and scan. The 5801 manual additionally lists distance and RPM; Sunny’s 5515 listing does not list those functions. The sources do not establish whether an unlisted readout is physically absent, so compare only what each source documents.

Check fit, storage, and risk before buying
- Weight limit: Sunny lists the 5515 at 250 lb. The located 5801 manual does not establish its maximum user weight. If choosing the 5801, confirm the limit directly with Sunny rather than relying on a reseller claim.
- Storage space: The 5515 has published assembled and folded measurements. The 5801 manual confirms vertical rail folding but lacks comparable measurements. Obtain the 5801’s current dimensions if your floor or storage space is tight.
- Resistance preference: The 5515 has a stated eight-level range. The 5801 has knob adjustment with no documented numbered range in the manual located here.
- Monitor needs: The 5801 manual documents distance and RPM in addition to the common readouts; the 5515 listing does not.
These are specifications, not comparative performance-test results. The available sources do not establish that one rower provides a smoother stroke, better durability, or a more effective workout.
