This deliberately limited source-checked sample covers Cubii Move, Sunny SF-E3872SMART and Sunny SF-E3959SMARTG. It does not claim to cover the market or identify a tested winner.
This guide is based on manufacturer documentation. We have not tested these products. Product links currently go to manufacturer pages and are not affiliate links. See our affiliate disclosure.

Source-checked specification table
Dimensions are manufacturer-reported length × width × height in inches. Weight is unit/product weight, not shipping weight. Every row includes its source and review date.
| Exact model | Controls/use | Dimensions, inches | Unit weight, pounds | Stride / pedal-step height, inches | Source / accessed |
|---|---|---|---|---|---|
| Cubii Move | Seated-only manual model; 6 resistance levels | 21.7 × 19.7 × 9.7 | Approximately 17.6 | Not confirmed in cited fields | Manual and product page; 2026-11-09 PT |
| Sunny SF-E3872SMART | 8 magnetic resistance levels; seated use | 22.6 × 18.5 × 10.6 | 25 | Stride 7; pedal minimum 3.5 / maximum 10.9 | Specifications; 2026-11-09 PT |
| Sunny SF-E3959SMARTG | Motorized, remote; 18 speed levels; seated use | 22.83 × 18.31 × 11.02 | 21.4 | Stride 6.9; pedal minimum 3.35 / maximum 10.9 | Specifications; 2026-11-09 PT |
A missing field is not zero, a negative product score or permission to substitute another model's specification.
Weight ratings require context
The Move manual lists a 300-pound maximum recommended user weight and also says never stand on the pedals, regardless of weight; accessed 2026-11-09 PT. Its rating is not standing permission.
The Sunny magnetic specifications did not publish a maximum user weight in the fields reviewed 2026-11-09 PT. The Sunny motorized page displayed “no limit” in that field on the same date. Its meaning remains unconfirmed here, so we do not present it as an unlimited safety rating or use it to rank capacity.
Interpret the controls before counting settings
The magnetic model lists resistance levels; the motorized model lists speed levels. Those are different control modes, not one common scale. A larger count does not establish a better workout or a directly comparable resistance. Sources: respective Sunny pages in the table, accessed 2026-11-09 PT.
Overall height does not establish your clearance
The magnetic page reports 10.6 inches overall height and 10.9 inches maximum pedal-step height; the motorized page reports 11.02 inches overall height and 10.9 inches maximum pedal-step height. These are distinct reported fields, not measurements of your knees or desk. Sources: respective Sunny pages, accessed 2026-11-09 PT.
Use the desk-clearance worksheet to document your setup and unanswered questions. Do not calculate a guaranteed fit from this table.
Why previously researched models are omitted
We prefer a smaller auditable table to an apparently complete table assembled from unresolved records.
- Cubii Go: the manual contains a width-unit inconsistency, so we have not presented a complete dimensional comparison. Reviewed 2026-11-09 PT.
- Cubii Total Body / Total Body+: the current page uses “Total Body,” while the manual names “Total Body+.” We have not sufficiently matched these versions to combine their specifications. Reviewed 2026-11-09 PT.
- Lifepro FlexStride: prior research recorded conflicting unit-weight information. The product page was checked again 2026-11-09 PT, but that discrepancy was not resolved. No definitive weight is restored here.
These gaps are not findings that the products are poor, unavailable or unsuitable.
FAQ
Does this identify the quietest machine?
No. We have not performed sound measurements or comparative noise tests. Qualitative manufacturer wording is not our test result.
Did this site measure the dimensions?
No. The table organizes manufacturer-reported figures with sources and dates.
Where are current prices?
Check the linked manufacturer's or seller's page and exact terms. We do not hard-code dollar amounts or claim a price advantage.
Can these be described as test data?
No. This is a source-linked compilation, not an independent test. Retain the exact model, units and source date when recording a field.
