Crossbones Running Bull Vibrating Cock Ring by Evolved

The Crossbones Running Bull Vibrating Cock Ring by Evolved is a dual-motor vibrating ring made to stimulate both partners simultaneously during partnered sex. Its patent-pending cross bullet system positions two independent 60mm vibrating bullets for targeted pleasure, while the waterproof construction and secure 40mm fit make it reliable for couples seeking intensified sensation.

About this product

The Crossbones Running Bull Vibrating Cock Ring by Evolved combines a snug silicone ring with a revolutionary dual-motor system that delivers targeted vibrations to both partners at once. The 15mm inner diameter wraps firmly around the base of the penis, whilst the patent-pending cross bullet configuration positions two independent 60mm bullets to stimulate different pleasure zones simultaneously. Unlike standard vibrating cock rings that deliver general buzzing from a single point, this ring uses separate motors to create focused, targeted sensation for both of you.

Evolved engineered this cock ring specifically for couples who want precision over simplicity. The waterproof design opens possibilities beyond the bedroom, whilst the phthalate-free material and lightweight 49-gram construction mean extended wear stays comfortable. The fixed 40mm diameter means no adjustment—just slip on and go.

The features that matter

• Cross bullet system: Patent-pending dual-motor placement targets specific pleasure points for him and her simultaneously, creating independent stimulation zones rather than uniform vibration.
• Phthalate-free material: Non-toxic silicone construction feels smooth against skin and resists degradation, holding up through regular use and thorough cleaning.
• Waterproof rating: Fully submersible design enables shower and bath play without compromising motor function or safety.
• Dual 60mm bullets: Two independent motors powered by 6 LR44 batteries deliver separate vibration intensity for each partner's preference.
• Secure 40mm fit: Fixed ring diameter grips consistently without slipping, maintaining contact with both vibrating bullets throughout partnered activity.

How to fit and wear a vibrating cock ring

Begin with a clean, dry penis and ensure both battery compartments are secured before use. Slide the 15mm opening over the head of the penis and roll it down to sit snugly at the base, just behind the testicles. The ring should grip firmly but not restrict blood flow—you should be able to slip one finger underneath comfortably. Position the two vibrating bullets so one sits against your underside and the other angles toward your partner's preferred zone during partnered contact.

Activation typically involves small buttons on each bullet to start, stop, or cycle vibration intensity independently. Start on the lowest setting to acclimatise to the sensation, then build intensity as comfort increases. Unlike adjustable rings such as Gates Of Hell C-Rings, this fixed-diameter design means you cannot loosen it mid-session, so ensure correct positioning before beginning. Remove by rolling it gently upward and off once finished. Rinse thoroughly with warm water and mild soap, then air dry completely before storing.

Who should buy it

Care and storage

Rinse both the ring and vibrating bullets thoroughly with warm water and mild soap immediately after use. Use a soft cloth to dry, paying special attention to battery compartment seals and motor casing edges. Store in a cool, dry place away from direct sunlight and extreme heat, which can degrade the silicone and battery performance. Replace LR44 batteries every 6–12 months depending on usage frequency, and keep fresh spares on hand. Never submerge the battery compartment in standing water for extended periods, even though the ring is waterproof.

The Crossbones Running Bull sits at the intersection of precision engineering and couples' pleasure—knowing its strengths and limits ensures you use it confidently.

What to expect

The dual-bullet design means the Running Bull behaves very differently from single-motor rings. First-timers often notice the vibration is more targeted and less diffuse; one bullet creates sensation in one zone while the other works independently elsewhere. This precision takes adjustment—some users expect the whole ring to buzz evenly, so the separated stimulation feels unusual initially but quickly becomes the appeal.

The 15mm inner diameter grips firmly without cutting off sensation. Most users find the fit reassuring during partnered activity because the ring stays put, but the fixed sizing means it either works for you or it doesn't—there is no mid-session adjustment. The waterproof construction is genuine; many buyers report shower and bath sessions as a highlight because water play adds a different dimension to the vibration sensation.

Battery life tends to run 4–6 hours on a fresh set, depending on intensity settings and which motors are active. The LR44 cells are widely available and inexpensive. Cleaning is straightforward—the silicone resists odour retention, and motor seals hold up well to soap and water. Motor longevity is typically 2–3 years with regular use.

Users who tend to return this ring often chose it hoping for adjustability or had a penis size outside the comfortable 40mm range. Those who keep it almost always appreciate the precision of dual motors and the waterproof reliability. It is not a beginner's first ring—it rewards buyers who already understand what they want from a vibrating cock ring.
