Every Configuration of the Bugaboo Donkey Explained (Mono, Duo & Twin)

March 3, 2026

Emily Gaylor

One of the biggest reasons parents love the Bugaboo Donkey is its flexibility. It’s not just a single stroller or a double. It's designed to grow with your family, converting between three different setups: Mono Mode (single), Duo Mode (siblings), or Twin (twins). In a world where baby gear seems to age out faster than your favorite newborn jammies, that kind of future-proofing really matters.

If you’ve ever caught yourself Googling what those modes actually mean—what fits in each setup, how wide the stroller gets, or what you need to buy to convert it—you’re definitely not alone. Our guide walks through every Donkey configuration, what setup each mode supports, and how the stroller adapts as your family grows.

How the Bugaboo Donkey Converts (Quick Overview)

Before you hit play: this demo features a previous Bugaboo Donkey model. The good news? The way the stroller converts between Mono, Duo, and Twin modes works the same on the new Donkey 6. So you can watch with confidence knowing the process you see here still applies.

The Donkey’s design is built around a smart, expandable frame that widens side-to-side when you’re ready to add a second rider. In single mode, the stroller stays narrower and uses that bonus space for a roomy side luggage basket (parenting involves so much stuff). When it’s time to grow, the frame slides open sideways to create room for a second seat or bassinet—no new stroller required.

You’re not replacing your stroller, you’re changing what it can do. The same chassis adapts as your family grows, which means fewer big gear swaps and a setup that matches your lifestyle.

In simple terms:

Mono Mode: Single stroller with extra side storage
Duo Mode: Side-by-side for siblings of different ages
Twin Mode: Side-by-side for twins

Does the Bugaboo Donkey 6 Expand the Same Way as Previous Models?

Yes! The Bugaboo Donkey 6 expands and converts exactly the same way previous Donkey models did. What’s changed is the naming, not the functionality. The expandable side-by-side frame, conversion process, and compatibility with bassinets, seats, and car seats all work the same as before. If you’re familiar with earlier Donkey models, you can think of the Donkey 6 as an upgrade in materials and design—not a reinvention of how the stroller grows.

Bugaboo Donkey Mono Mode

Mono mode is the Donkey’s single-child configuration. The Donkey single stroller (formerly Mono Complete) includes one multi-use seat frame, meaning the same frame supports both bassinet and toddler seat fabrics—you simply swap the fabric as your baby grows.

In single mode, the stroller stays in its narrower width and includes a side luggage basket in place of a second seat. When you’re ready to expand to a double stroller, the same frame can be converted by adding the appropriate expansion components.

What Fits in Single Setup

The bassinet + side luggage basket for newborns
The toddler seat + side luggage basket for babies 6 months and up
A compatible infant car seat with Maxi-Cosi or Chicco Adapters + side luggage basket

Popular Add-Ons for Single Setup

Bugaboo Donkey Maxi-Cosi or Chicco Car Seat Adapters
Useful if you want to use the stroller as a travel system for quick errands or transfers from the car.

Bugaboo Organizer or Cup Holder
Keeps essentials like phone, keys, and drinks within easy reach while the side basket handles larger items.

Bugaboo Comfort Transport Bag
Protects your stroller during air travel or long-distance transport, helping prevent scuffs, dirt, and damage. A smart add-on if you plan to fly or frequently pack the stroller in a car trunk or cargo area.

Bugaboo Donkey Duo Mode

Double setup (Duo or Sibling Mode) is the Donkey’s side-by-side configuration for two kids (usually siblings of different ages). To create a double configuration, you’ll need:

The Bugaboo Donkey (includes one multi-use seat frame).
The Bugaboo Donkey Sibling Seat (adds the second seating position and additional frame).

The Donkey Sibling Seat (formerly the Duo Extension) allows you to configure the stroller with either a bassinet and toddler seat or two toddler seats, depending on your kiddo’s ages and stages. The frame expands sideways to create space for the second seating position, so both children ride next to each other rather than front-to-back.

This configuration keeps both riders at the same height and within easy reach, which many families find more convenient for sibling interaction and supervision. Both seats have identical weight limits, can face parent or world, and recline independently. So if your toddler suddenly has a lot of opinions, the Donkey gives you flexibility as their preferences change.

What Fits in Double Mode

Typical Double setups include:

Bassinet + seat for a newborn and toddler
Seat + seat for two older children
Infant car seat + seat with compatible adapters

Popular Add-Ons for Double Mode

Bugaboo Snack Tray
Avoid meltdowns and keep snacks and drinks within easy reach for toddlers and preschoolers.

Bugaboo Thermolite Performance Footmuff
Adds cozy warmth for chilly and brisk mornings, keeping little riders comfy without the need for heavy jackets in the stroller. A great pick if you spend time outside year-round or live in colder regions.

Bugaboo Dual Comfort Seat Liner
Creates an extra layer of breathable comfort and helps protect the stroller seat from everyday messes, making cleanup easier after snacks, spills, or warm-weather outings.

Bugaboo Donkey Twin Mode (Twin Configuration)

Twin mode is designed for families with twins who want two children riding side by side from the very beginning. Most families use this setup with two bassinets for newborn twins or with two infant car seats using the appropriate twin adapters, depending on what works best for their day-to-day routine.

The Donkey stroller includes one multi-use seat frame that can be used as either a bassinet or a toddler seat—just swap the fabric as your little ones grow.

To create a Twin configuration, you’ll need:

The Bugaboo Donkey (includes one multi-use seat frame).
The Donkey Sibling Seat (adds the second seating position and an additional frame).
The Twin Bassinet fabric set (used with the second frame from the Sibling Seat and canopy to create the second bassinet)

Once assembled, the stroller expands sideways to attach two identical bassinets positioned next to each other. It's a balanced layout that makes for easy pushing and maneuvering, and keeps both babies visible and within reach. Families who prefer quick transfers or plan to skip the bassinet stage can also use two compatible infant car seats with twin adapters instead.

As your babies grow, the same setup can later transition to two toddler seats using the appropriate seat fabrics.

What Fits in Twin Mode

Typical Twin setups include:

Bassinet + bassinet for newborn twins
Infant car seat + infant car seat using compatible twin adapters
Seat + seat as twins grow into toddlerhood

Accessories That Pair Well With Twin Bassinet Mode

Bugaboo Twin Maxi-Cosi or Chicco Car Seat Adapters
Allows you to attach two compatible infant car seats side by side—a super helpful option for families skipping the bassinet stage or prioritizing quick transfers.

Bugaboo Comfort Wheeled Board
A helpful add-on for families with an older sibling in the mix. The Comfort Wheeled Board clicks onto the Donkey and gives big kids the option to ride along standing or seated, while the offset positioning helps preserve valuable walking space for parents navigating a fully loaded stroller.

Bugaboo Donkey Infant Car Seat Compatibility and Adapters

The Bugaboo Donkey works with many infant car seat brands across Single, Double, and Twin setups using the right adapters. That makes it easy to create a flexible travel system for quick errands, daycare drop-offs, or those moments when you’d really rather not wake a peacefully sleeping baby.

If infant car seats are part of your plan (especially two at the same time), it’s a good idea to confirm compatibility and adapter requirements ahead of time, since fit can vary by model and year.

Living with the Bugaboo Donkey Day to Day

The Bugaboo Donkey is designed for flexibility and longevity, which means it naturally takes up more space than ultra-compact strollers. In all modes, it fits through standard doorways and has plenty of storage. Keep in mind that when expanded into Double or Twin configurations, the stroller becomes wider, so tighter entryways, elevators, or frequently used indoor spaces may be trickier to maneuver.

When it comes to transport, the Donkey isn’t a grab-and-go travel stroller. It has a larger folded footprint and may require some trunk planning, especially in smaller vehicles. Many families find it fits more comfortably in SUVs, wagons, or larger trunks, and occasional component removal can help with packing.

On the move, the Donkey is known for balanced steering and an A+ smooth push, even when fully loaded. The side-by-side layout distributes weight evenly, which helps maintain stability and control on sidewalks, neighborhood walks, and park paths.

Frequently Asked Questions

Can the Bugaboo Donkey fit through standard doorways?

In Single (Mono) mode, the Bugaboo Donkey fits through most standard residential doorways. When configured as a Double (Duo) or Twin, the stroller becomes wider, which can make tight indoor spaces more challenging. If you frequently navigate narrow hallways, older buildings, or elevators, it’s a good idea to measure those spaces ahead of time to avoid surprises.

What’s the difference between Double and Twin configurations?

Double mode is designed for siblings of different ages, typically using a bassinet and seat or two seats. Twin mode is designed for two children of the same stage, such as two bassinets for newborn twins or two seats for older twins. Both configurations use the expandable frame, but the required accessories and setup differ based on how many seating positions you’re adding.

Can you convert the Bugaboo Donkey later as your family grows?

Yes. One of the Donkey’s biggest strengths is its ability to evolve over time. Families often start in Single mode, then expand into Double or Twin configurations as their needs change. Additional kits and fabrics allow you to adjust the setup without replacing the entire stroller. And you can always convert back to a single if you expand your family and have older siblings that are beyond the stroller stage.

Can you use infant car seats with the Bugaboo Donkey?

Yes. With the appropriate adapters, many popular infant car seats can be used across configurations. Compatibility varies by brand and model, so it’s important to confirm fit and adapter requirements before purchasing—especially if you plan to use two car seats at the same time.

Is the Bugaboo Donkey hard to push when fully loaded?

Despite its size, the Donkey is known for balanced weight distribution and smooth steering, even when carrying two children. The side-by-side design helps maintain stability and control, making it comfortable for everyday walks, sidewalks, and park paths.

How much storage does the Bugaboo Donkey offer?

Storage capacity changes depending on configuration. In Mono mode, the stroller includes a large side luggage basket in addition to the under-seat basket. When expanded into Double or Twin modes, that side basket becomes a second seating position, so many families rely more on organizers and handlebar accessories for everyday essentials.

How long can you realistically use the Bugaboo Donkey?

The Donkey is designed to support families from newborn through toddler years and beyond. With the ability to transition between bassinets, seats, and multiple child configurations, many families use the stroller for several years as their children grow and needs evolve.
