The Bugaboo Donkey3 combination stroller adapts to many different uses - you can convert strollers in an instant for one or two children. Leave for day care as Duo in the morning, continue your trip as Mono and load your shopping cart into the convenient side basket or large lower basket. The Bugaboo Donkey3 combination stroller is convenient even with a full load, and you can move and turn the strollers with one hand. This model is perfect for a growing family, as the Donkey Mono stroller can be expanded to a two-child stroller with an expansion pack. The strollers also have plenty of space thanks to the side basket and spacious underseat basket.
