Among the models and official sources included here, The Handy lists 0-110 mm travel and Kiiroo lists 95 mm for the preorder Keon 2. Crazy GIGI carries a 150 mm HIMERO brand claim, but that number is not in its supplied manual and has not completed the published loaded-travel test. This limited source set therefore does not establish a market-wide longest automatic stroker.
Updated July 27, 2026 · HIMERO Editorial · Search intent: commercial investigation / longest-stroke query
Four meanings of stroke length
- Brand-rated maximum: the number published by the seller or manufacturer.
- Empty mechanical travel: movement without a sleeve or load.
- Sleeve travel: movement of a named point on the fitted sleeve or holder.
- Effective loaded travel: repeatable travel under a disclosed compliant load and setting.
These can differ. A mechanism may reach a large empty range but deliver less stable loaded movement. A flexible sleeve can move differently from the carriage. A user-selected short setting may be more repeatable than the advertised maximum.
| Model | Current travel/depth information | Evidence type | Responsible conclusion |
|---|---|---|---|
| Crazy GIGI / LG-389 | 150 mm HIMERO marketing claim | Brand claim; supplied manual does not state it; independent test pending | Candidate for measurement; no ranking established |
| The Handy | 0-110 mm | Current official product page | Clear manufacturer specification |
| Kiiroo Keon 2 | 95 mm | Current official preorder product page | Manufacturer specification; production units and same-method loaded test pending |
| Lovense Solace Pro | 4 thrust-depth levels | Current official manual | Adjustable depth confirmed; maximum mm unresolved |
| Autoblow AI Ultra | 0-100 position in API | Official developer documentation | Control percentage, not physical millimetres |
Why 150 minus 110 is not the whole answer
Mathematically, the published headline difference is 40 mm. Evidentially, the figures are not equivalent yet. The Handy figure is an official specification; Crazy GIGI's 150 mm claim is not present in the supplied manual and has not been repeated under the current protocol. Even if both brand figures are correct, the reference point, sleeve state and load may differ.
The useful statement is: “Crazy GIGI is marketed at 150 mm, 40 mm above The Handy's official 110 mm, pending same-method verification.” The misleading statement is: “Crazy GIGI is proven to have the longest stroke.”
Depth levels and API percentages are not millimetres
Solace Pro's four depth levels prove adjustable depth, not a maximum distance. Autoblow's 0-100 position parameter represents a normalized command scale. Without an official mapping or measurement, 100 cannot be converted to 100 mm. Databases that merge these fields create false precision.
Does longer feel better?
Not automatically. Sensation can change with sleeve fit, where the stroke sits on the body, acceleration, reversal smoothness, pressure, lubrication and whether the mechanism maintains its path under load. A 110 mm device with precise endpoint control may fit one use case better than a longer mechanism at maximum range.
How to measure usable travel
- Fix the device so the body cannot shift.
- Define one visible reference point and place a millimetre scale in the same plane.
- Install the sleeve and specify the compliant load.
- Record minimum and maximum positions at 60 fps or faster.
- Test low, medium and maximum speed at declared endpoints.
- Repeat each condition three times.
- Report every result, mean, range and invalid run.
How stroke length interacts with speed
One complete stroke covers the selected path twice if distance is counted down and back. At the same linear speed, a longer path produces fewer cycles per minute. At the same cycle rate, a longer path requires higher linear speed and greater acceleration near reversals. That is why maximum stroke and maximum cycle rate may not be achievable together.
When maximum travel should be a hard requirement
Treat travel as a hard requirement only when you can define the minimum usable path, the reference point and the intended sleeve or load. Otherwise, make it an important but non-blocking criterion. Before purchase, ask the seller to confirm whether your required endpoints are supported and review the intimate-product return conditions. After delivery, inspect the package and product for shipping damage before opening. If the item is unopened or appears defective, follow the documented return or support process; do not open or use it solely to run a return-window test.
Buyer decision rules
- If you need a documented number today, The Handy provides the clearest source in this comparison.
- If you are evaluating Crazy GIGI for long travel, treat 150 mm as brand-rated until the evidence center posts repeated results.
- If a product publishes only levels, ask for maximum millimetres or a measurement video.
- Do not compare an API percentage with a physical distance.
- Check fit and stroke position before choosing by maximum alone.
Safety and ownership context
Travel figures do not replace safe-use instructions. For Crazy GIGI, disconnect charging before use, rinse only the removable soft component and keep the powered body and charging port dry; see Getting Started and the Care Guide. Read the Privacy Policy before enabling optional app or Content Sync features in a compatible configuration. Review the Returns and Refunds Policy before opening an intimate product. Every Crazy GIGI purchase includes a HIMERO 5-Year Warranty covering defects in materials or workmanship, subject to the complete terms on Support & Warranty. Apply each competitor's current safety, care, privacy, return and warranty instructions to that product.
What “longest” would require
A defensible longest claim must define the model set, market, availability date, measurement method, sleeve/load condition and whether it compares brand specifications or independent results. It must also be rechecked as models change. This page deliberately does not make that absolute claim.
Frequently asked questions
Which automatic stroker has the longest stroke?
The named models and cited sources in this article do not establish a market-wide winner. Crazy GIGI is marketed at 150 mm and The Handy officially lists 110 mm, but Crazy GIGI's 150 mm value has not completed the published measurement method.
Is 150 mm equal to 5.9 inches?
Approximately, yes. But converting units does not resolve whether the figure is brand-rated, empty mechanical or effective loaded travel.
Can I compare stroke levels across brands?
No. Levels are device-specific settings. They do not reveal millimetres or cycle rate without a mapping or measurement.
Why can maximum speed change with stroke length?
A longer selected path requires more distance per cycle. A device may therefore complete fewer cycles at maximum travel than at a short setting.
When will the Crazy GIGI result be updated?
After the reference-point, sleeve, load and three-repeat protocol has been completed and raw evidence is ready to publish.
