Whether you’re looking for the most powerful vibrations, the quietest operation, or the best value for your money, I’ll help you make an informed decision. I’ll even reveal a third option that many users consider superior to both!
A Brief History:
Before diving into the comparison, let’s understand the origins of these two iconic machines.
The Original Pioneer: Sybian
The Sybian was invented by Dave Lampert in the 1980s and officially launched in 1987. For decades, it dominated the market as the premier ride-on sex machine, becoming almost legendary in status.
Lampert created the Sybian after observing that women often achieved more intense orgasms when on top during intercourse. His goal was to design a machine that could deliver consistent, powerful stimulation without the limitations of human stamina.
The classic Sybian design has remained largely unchanged for over 30 years – a testament to its effective design, but also a potential limitation in an era of rapid innovation.
The Modern Challenger: The Cowgirl
The Cowgirl entered the market much more recently, launched by COTR, Inc. (the company behind b-Vibe and Le Wand) in 2018. It was specifically designed to challenge the Sybian’s long-standing dominance with modern features and aesthetics.
With its sleek design, smartphone compatibility, and premium branding, The Cowgirl positioned itself as the luxury, tech-forward alternative to the more utilitarian Sybian.
The Cowgirl was created with both performance and visual appeal in mind, targeting users who want their pleasure products to look as good as they feel.
Design & Comfort: Which Machine Feels Better?
The physical experience of using these machines is crucial – comfort can make the difference between an amazing session and an awkward one.
Sybian Design
The Sybian features a more utilitarian design with a barrel-shaped base covered in vinyl or leather-like material. It weighs approximately 22 pounds and measures about 13.25″ x 12.5″ x 10″.
Many users describe the Sybian as “old-school” or “clinical” in appearance. It’s functional but not particularly aesthetically pleasing.
The classic design includes a wired remote control with two dials – one for vibration intensity and one for rotation speed. This analog approach is simple but lacks the precision of digital controls.
“The Sybian looks like it was designed in the 80s because it was. It’s not winning any beauty contests, but the vinyl cover is easy to wipe down, and the shape is actually pretty comfortable for longer sessions.”
The Cowgirl Design
The Cowgirl features a more modern, premium aesthetic with a saddle-shaped base covered in vegan leather. It’s slightly heavier at about 25 pounds and measures approximately 13.4″ x 12.5″ x 9.5″.
The design is more visually appealing with attention to details like stitching and texture. Many users mention that it “looks like a luxury product.”
The Cowgirl comes with both a wired remote and smartphone app control capabilities, offering more precise adjustments and pattern options than the Sybian.
“The Cowgirl just looks and feels more premium. The vegan leather is soft against the skin, and the shape contours better to my body. It’s something I don’t mind having visible in my bedroom.”
Comfort Comparison
After analyzing dozens of user experiences, I found that comfort preferences were split, but with some consistent patterns:
Sybian Comfort Pros
- More stable base that rarely shifts during use
- Slightly lower profile makes mounting easier for some users
- Vinyl cover is non-porous and easy to clean
- Lighter weight makes it somewhat easier to move and store
Sybian Comfort Cons
- Firmer padding can become uncomfortable during longer sessions
- More barrel-shaped design doesn’t contour as well to all body types
- Vinyl material can feel sticky against skin in warm environments
- Limited color options (beige, black, purple, or red)
The Cowgirl Comfort Pros
- Saddle shape contours better to most body types
- Softer vegan leather feels more comfortable against bare skin
- More padding provides cushioning for longer sessions
- Premium aesthetic makes it feel like a luxury experience
The Cowgirl Comfort Cons
- Heavier weight makes it more difficult to move
- Vegan leather can be harder to thoroughly clean
- Higher profile requires more effort to mount for some users
- Limited color options (pink or brown)
The comfort winner depends largely on your body type and preferences, but The Cowgirl edges out the Sybian for most users in terms of comfort during extended sessions.
Performance & Power: Which Delivers Stronger Orgasms?
When it comes to these premium machines, performance is paramount. Let’s compare their power, vibration quality, and customization options.
Technical Specifications Comparison
| Feature | Sybian | The Cowgirl |
| Max Vibration RPM | 6,000 RPM | 6,500 RPM |
| Max Rotation RPM | 150 RPM | 150 RPM |
| Vibration Patterns | Continuous only | 6 patterns via app |
| Control Options | Wired remote only | Wired remote and smartphone app |
| Power Source | AC power (110V or 220V) | AC power (100-240V) |
| Weight Rating | Up to 400 lbs | Up to 400 lbs |
User Experiences: Vibration Quality
Based on user feedback, there are some notable differences in how the vibrations feel:
“The Sybian has these deep, rumbly vibrations that penetrate really deeply. It’s almost overwhelming at first, but that’s what makes it so effective. The Cowgirl feels more refined but slightly less powerful at the highest settings.”
“I prefer The Cowgirl’s vibration quality. It has a better range from gentle to intense, while the Sybian starts at ‘pretty strong’ and goes to ‘oh my god’. The patterns on The Cowgirl app also add variety that the Sybian lacks.”
The performance verdict: The Sybian has a slight edge in raw power, while The Cowgirl offers more versatility and control options. For pure intensity, the Sybian wins by a narrow margin, but The Cowgirl provides a more customizable experience.
Attachments & Versatility: Which Offers More Options?
Both machines rely on attachments to provide different sensations. The quality, variety, and compatibility of these attachments significantly impact your experience.
Sybian Attachments
The Sybian offers a wide range of attachments developed over its long history:
- Material options: TPE (cheaper) or silicone (premium)
- Non-insertable options: Flat, smooth, textured, and ridged
- Insertable options: Various sizes, shapes, and textures
- Specialized options: G-spot, prostate, and anal-safe designs
Sybian attachments range from $10-$59 depending on material and complexity. The company offers both flesh-colored and purple options.
A common complaint is that the TPE attachments are porous and cannot be fully sanitized, while the silicone options are significantly more expensive.
The Cowgirl Attachments
The Cowgirl offers fewer attachments but focuses on quality:
- Material: All premium silicone (body-safe and non-porous)
- Standard options: Rawhide (non-insertable) and Wild West (insertable)
- Additional options: G-spot, textured, and specialized designs
The Cowgirl attachments are priced around $60 each. While there are fewer options than for the Sybian, all are made from body-safe silicone.
Users consistently praise the quality of The Cowgirl’s attachments, though some wish for more variety.
Attachment Compatibility
An important consideration is whether attachments are interchangeable between machines:
Important note: While some users report success using Sybian attachments on The Cowgirl and vice versa, the manufacturers do not officially support cross-compatibility. Attempting to use attachments from one machine on the other may void warranties and could potentially damage the machines.
The attachment verdict: The Sybian offers more variety but inconsistent quality, while The Cowgirl provides fewer options but higher overall quality. If attachment variety is your priority, the Sybian has an advantage. If you prefer premium materials and are concerned about body safety, The Cowgirl is the better choice.
Noise Level & Discretion: Which is Quieter?
For many users, noise level is a crucial factor, especially if you have roommates, thin walls, or simply prefer a more discreet experience.
Noise Comparison
Based on user reports and technical specifications:
| Intensity Level | Sybian Noise Level | The Cowgirl Noise Level |
| Low (25%) | 45-50 dB (whisper to quiet conversation) | 40-45 dB (library whisper) |
| Medium (50%) | 55-60 dB (normal conversation) | 50-55 dB (quiet conversation) |
| High (75%) | 65-70 dB (vacuum cleaner) | 60-65 dB (loud conversation) |
| Maximum (100%) | 70-75 dB (dishwasher) | 65-70 dB (vacuum cleaner) |
“The Sybian sounds like a small airplane taking off at max settings. I can only use it when no one else is home. The Cowgirl is definitely quieter, but still not what I’d call ‘discreet’ at higher intensities.”
“I put my Cowgirl on the bed instead of the floor and it reduced the noise significantly. With music playing, you can’t really hear it from the next room unless it’s on the highest settings.”
Noise Reduction Tips
Users have shared several effective strategies for reducing noise with both machines:
- Place the machine on a bed rather than a hard floor
- Use a thick foam exercise mat underneath
- Play music or white noise to mask the sound
- Use during times when housemates are away
- Keep the machine well-maintained (some noise comes from loose parts)
The noise verdict: The Cowgirl is consistently quieter than the Sybian across all intensity levels, making it the better choice if noise discretion is a priority. However, neither machine could be considered truly “quiet” at higher settings.
Price & Value: Which Gives You More for Your Money?
These are significant investments, so understanding what you get for your money is crucial.
| Product | Base Price | What’s Included | Warranty |
| Sybian | $1,245 | – Sybian machine – Matching stool – Wired controller – 3 attachments (choice of TPE or silicone) – Instruction manual |
5 years |
| The Cowgirl | $1,499 – $1,899 | – The Cowgirl machine – Wired remote controller – 2 silicone attachments – Global power adapter – Instruction manual – Storage bags for attachments |
2 years |
Additional Costs
Beyond the initial purchase, consider these potential additional expenses:
Sybian Additional Costs
- Premium silicone attachments: $40-$59 each
- TPE attachments: $10-$30 each
- Fluid-proof cover: $99
- Storage cabinet: $365
The Cowgirl Additional Costs
- Additional attachments: ~$60 each
- Branded storage case: $149
- App is free but requires compatible smartphone
“I’ve owned my Sybian for 7 years now and it still works perfectly. The initial cost was high, but when you break it down by use, it’s been one of my most cost-effective toys. I’ve only had to replace attachments.”
“The Cowgirl is definitely expensive, but the app functionality and overall quality make it worth it for me. I do wish the warranty was longer considering the price point.”
The value verdict: The Sybian offers better long-term value with its longer warranty and proven durability. The Cowgirl provides more modern features but at a higher price point. If longevity is your priority, the Sybian is the better value. If you value technology and aesthetics, The Cowgirl may be worth the premium.

Budget-Friendly Alternatives
If the premium price tags of these machines are beyond your budget, there are more affordable alternatives that can provide similar experiences:
Liberator BonBon
At around $110, this foam mount lets you attach your favorite vibrator or dildo for a hands-free experience. While not motorized, it provides a similar riding position at a fraction of the cost.
Lovebotz Saddle Deluxe
At approximately $855, this is a more affordable motorized option. While not as powerful or durable as the premium machines, it offers similar functionality at about half the price.
The Tremor
At around $849, The Tremor offers a middle ground between budget options and premium machines. It features silicone attachments and a unique design focused on comfort and hygiene.
Frequently Asked Questions
Are these machines worth the high price?
Based on user feedback, these machines provide experiences that cannot be replicated by standard vibrators or dildos. Most users who make the investment report high satisfaction and years of use, making the cost-per-use quite reasonable over time. However, they are significant investments and not necessary for everyone’s pleasure journey.
How long do these machines typically last?
The Sybian has the longest track record, with many users reporting 10+ years of regular use without issues. The Cowgirl and Motorbunny are newer to market but are built with similar industrial-grade components. With proper care and maintenance, all three machines should provide many years of service.
Can men use these machines?
Yes, all three manufacturers offer attachments designed for prostate stimulation. The machines can be used by anyone regardless of gender, though they were primarily designed with vulva owners in mind. The Motorbunny Buck’s thrusting capability may offer additional options for different anatomies.
Are these machines safe to use?
When used as directed, these machines are safe. They all use standard household electricity and include safety features to prevent electrical hazards. The main safety considerations are using appropriate lubricant with attachments (water-based for silicone attachments) and starting at lower intensity settings before increasing power.
Can I return these machines if I’m not satisfied?
Return policies vary by manufacturer and retailer. Sybian offers a 45-day satisfaction guarantee when purchased directly from their website. The Cowgirl and Motorbunny typically have more limited return policies due to the intimate nature of the products. Always check the specific return policy before purchasing.
My Final Recommendation: Sybian vs The Cowgirl vs Motorbunny Buck
After extensive research and analysis of user experiences, here’s my honest recommendation:
If I had to choose just one machine, I would recommend the Motorbunny Buck. It combines the best features of both the Sybian and The Cowgirl while adding the unique thrusting capability that neither competitor offers. The combination of vibration and thrusting creates sensations that users consistently describe as superior to either traditional machine.
However, the best choice ultimately depends on your specific priorities:
- If raw power and proven durability are your top priorities, choose the Sybian.
- If you value aesthetics, comfort, and modern technology, choose The Cowgirl.
- If you want the most versatile experience with both vibration and thrusting, choose the Motorbunny Buck.
Whichever machine you choose, you’re investing in a premium experience that standard toys simply can’t match. These machines represent the pinnacle of pleasure technology and can provide years of satisfaction when properly maintained.
