Published machine height alone cannot confirm that your knees and shoes clear your desk throughout pedaling. Record the space you have, the exact model's documented dimensions and the fit questions still unanswered. This worksheet does not establish a universal minimum clearance or certify a fit.
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.
Start with your actual desk and chair
Make a record of the intended setup, not an assumed standard desk. Identify the lowest obstruction beneath it, such as an apron, drawer or keyboard tray. Note usable floor space and intended chair position. Follow the chair's and device's instructions; this page does not replace them.
These are observations for you to collect. They are not measurements taken by this site, and a completed record is not a fit test performed by us.
Keep overall height and pedal-step height separate
The Sunny SF-E3872SMART documentation reports 22.6 × 18.5 × 10.6 inches overall dimensions and 3.5 inches minimum / 10.9 inches maximum pedal-step height; accessed 2026-11-09 PT.
The Sunny SF-E3959SMARTG documentation reports 22.83 × 18.31 × 11.02 inches overall dimensions and 3.35 inches minimum / 10.9 inches maximum pedal-step height; accessed 2026-11-09 PT.
The maximum pedal-step values match while the overall heights differ. That comparison does not establish equal user fit. Neither field supplies your knee-motion measurement. Do not add height fields together or use either as a guaranteed clearance requirement.
Your measurement and question worksheet
Leave any value unconfirmed if you cannot verify it. Record units and a source or observation date alongside your notes.
| Question | Your measurement or note | Evidence to record | Status |
|---|---|---|---|
| Floor to lowest desk obstruction? | Fill in | Your observation/date | Unconfirmed until recorded |
| Usable floor length and width? | Fill in | Your observation/date | Unconfirmed until recorded |
| Exact device model and version? | Fill in | Manufacturer page/manual | Unconfirmed until matched |
| Manufacturer's overall dimensions? | Fill in | Field, units, URL/access date | Unconfirmed until sourced |
| Published minimum/maximum pedal-step height? | Fill in, or not published in source reviewed | Exact source fields | Do not substitute body height |
| Intended chair position and adjustments? | Fill in | Setup notes/relevant instructions | Not assessed by this site |
| Has knee/shoe movement clearance been verified? | Fill in, or not verified | What was checked, by whom/date | No automatic fit score |
| Remaining questions before buying? | Fill in | Questions for manufacturer/seller | Keep open until answered |
Shorter users: don't rely on a height label
This research has not established a minimum user height or a “best for short people” ranking. Instead, record what you need to confirm: pedal reach from your intended chair position, available space and the exact device's setup restrictions.
A manufacturer's overall dimensions do not answer every personal-fit question. Seek clarification before buying if key information remains unknown. Check current seller terms yourself; this page does not promise a return option.
Read use restrictions before trying a setup
The Move manual reports 21.7 × 19.7 × 9.7 inches, but also requires seated use and prohibits standing on the pedals. Its 300-pound maximum recommended user weight does not override that warning; accessed 2026-11-09 PT.
Do not stand on a seated-only device to check fit. Read the exact model's instructions rather than applying another product's rating to it.
FAQ
How much clearance do I need?
There is no source-backed universal number established here. Keep your setup observations separate from product dimensions and from personal movement clearance that remains unverified.
Is a lower machine always better for a low desk?
We cannot promise that. The cited Sunny examples publish distinct body-height and pedal-step fields. Our research does not contain your individual knee-motion measurements.
Which model is best for a short person?
We cannot identify one from a person's height alone. Document reach, chair position and exact-model instructions instead of relying on an invented cutoff.
Does the worksheet give a pass/fail result?
No. It is an evidence and question record, without an automatic fit calculation, ergonomic certification or medical assessment.
