Lovense Sex Machine vs Motorbunny Buck: Thrusting and Control

The Lovense Sex Machine is presented by Lovense as an adjustable automatic thrusting machine, controllable through the Lovense Remote app. The Motorbunny Buck is described by Motorbunny as the first hybrid machine combining a saddle-type vibrator with a thrusting mechanism, shipped with a Bluetooth LINK controller and three silicone attachments. Both devices therefore target the same territory—powerful, fixed machines—but take two very different approaches. This comparison looks solely at what each brand publishes on its product pages: neither machine has been tested by us.

What each brand claims

Thrusting: hard numbers from Lovense, a hybrid concept from Motorbunny

Lovense publishes a detailed comparison table for its Sex Machine: a variable-speed motor advertised at up to 300 strokes per minute and a maximum thrust stroke of 11.5 cm, with noise level listed at 61 dB. The brand also stresses that the machine can be adjusted in several ways to achieve different positions. Motorbunny, on the other hand, discloses neither speed, nor stroke length, nor noise level on its page: the pitch centers on the device’s core concept, billed as the only hybrid machine combining a vibrating saddle with thrusting motion, featuring two thrust-movement dials and three silicone attachments. The two brands simply aren’t speaking the same language: one documents its numbers, the other highlights a combination of stimulations. Without independent testing, these remain just claims.

Control: connected app versus dedicated controller

This is the clearest difference between the two pages. Lovense advertises control via the Lovense Remote app, compatible with iPhone, iPad, and iPod Touch running iOS 11.0 or later, Android 5.0 or later with Bluetooth 4.0, Mac via Bluetooth 4.0, and Windows using the Lovense USB Bluetooth adapter. The brand explicitly cites short-range control, long-range control, music sync, and sound-activated vibrations, describing a design meant for both solo use and partner play. Motorbunny states that the Buck ships with a Bluetooth LINK controller, but its page mentions no mobile app, no long-range control, and no syncing to sound or music. For anyone wanting to hand the controls to a remote partner, only the Lovense page describes that possibility.

Attachments and customization: the Vac-U-Lock ecosystem

Motorbunny highlights the Buck’s modularity. The standard kit, per the brand, includes three silicone attachments named sweet spot, thumper, and low, plus a right-angle wedge. A Doc Johnson Vac-U-Lock adapter, offered in a dedicated bundle or sold separately depending on the page, allows use of Vac-U-Lock–compatible accessories: Motorbunny mentions hundreds of options for choosing shape, size, color, and material. The Vac-U-Lock bundle is advertised with the adapter plus two 7.5-inch accessories. The Lovense page doesn’t detail an equivalent attachment catalog; it mentions a discreet storage bag included and simple assembly. On the subject of accessory customization, Motorbunny’s pitch is the more detailed of the two.

Size, footprint, and published specs

Lovense provides precise figures in its machine comparison table: 1027 x 260 x 450 mm and roughly 11.4 kg for the Sex Machine, versus 606 x 252 x 292 mm and 3.2 kg for the Mini Sex Machine, which helps in planning space and storage. The Motorbunny page lists no dimensions, weight, or noise level for the Buck: nothing can be inferred from this, and we won’t attempt to. Neither page mentions a waterproof rating or IP rating, which calls for caution regarding use in a shower or bath. On the commercial side, however, Motorbunny advertises an 11-year warranty and a 45-day satisfaction guarantee, which are absent from the Lovense page reviewed.

Two different usage philosophies

Lovense describes a machine built for three explicit scenarios: solo play, short-range control, and long-range control, with easy assembly, a frame advertised as sturdy and stable, and operation the brand describes as quiet. Motorbunny instead describes a seated experience, straddling a vibrating saddle, complemented by a thrusting motion and interchangeable attachments. The former leans on connectivity and app-based control, the latter on physically combining two types of stimulation and on the breadth of its accessory catalog. The choice depends less on raw power—impossible to compare given the lack of shared data—than on how one wants to use the machine and how much of a role the smartphone should play.

Where the Buck has the edge

The Motorbunny page highlights a concept Lovense doesn’t offer: a vibrating saddle combined with a thrusting mechanism, meaning two types of stimulation in a single device, with two movement dials. The kit, according to the brand, is generously stocked: three silicone attachments, a right-angle wedge, the power adapter, and the Bluetooth LINK controller. Access to the Doc Johnson Vac-U-Lock ecosystem allows, per Motorbunny, choosing among hundreds of accessories to adjust shape, size, and material. The brand also advertises an 11-year warranty and a 45-day satisfaction guarantee.

Lovense Sex Machine or Buck: which one to choose?

The Lovense Lovense Sex Machine — The Lovense Sex Machine suits those who want app-based control, both short- and long-range, with music sync and sound activation, and who want hard numbers before buying: an advertised speed of up to 300 strokes/min, an 11.5 cm stroke, 61 dB, and published dimensions and weight.

The Motorbunny Buck — The Motorbunny Buck is better suited to those looking for seated stimulation combining saddle vibration and thrusting, with a physical controller included rather than an app, and who want to take advantage of the wide range of Vac-U-Lock accessories described by the brand.

Frequently Asked Questions

Can control be handed over to a partner remotely?

Only the Lovense page describes this: the brand advertises short-range and long-range control via the Lovense Remote app, compatible with iOS 11.0 and above, Android 5.0 and above with Bluetooth 4.0, Mac, and Windows with the Lovense USB Bluetooth adapter. The Motorbunny page mentions a Bluetooth LINK controller included, but says nothing about a mobile app or long-range control.

Are these machines waterproof?

Neither page reviewed indicates a waterproof rating, IP rating, or water-resistance claim for these devices. In the absence of manufacturer data, we can’t confirm anything. Since both machines are large, fixed devices, it’s wise to check with the brand’s customer service before any use near water.

Which machine is quieter?

They can’t be ranked. Lovense publishes a noise level of 61 dB for the Sex Machine in its comparison table and describes quiet operation. Motorbunny provides no sound figure for the Buck on its product page. Comparing a number to an absence of a number wouldn’t make sense, and we haven’t tested either device under real conditions.

What exactly is included in each kit?

Lovense states that the Sex Machine ships with a discreet storage bag and emphasizes easy assembly along with several position adjustments. Motorbunny goes into more detail: the Buck is advertised with the Bluetooth LINK controller, the power adapter, a right-angle wedge, and three silicone attachments. The Vac-U-Lock bundle adds, according to the brand, the adapter plus two 7.5-inch accessories.
