This item contains the Bugaboo Donkey 5 stroller chassis that forms the basic structure of your stroller. The wheels and top handlebar grips are not included but can be purchased separately. Made from lightweight and durable materials, it houses the integrated suspension system and has been designed with the best comfort and safety of your baby in mind. The chassis contains extension levers and buttons, which means you can easily transform the Bugaboo Donkey 5 from a single stroller to double, and vice versa. It can support the weight of two growing children, whether you’re using it in Mono or Duo/Twin configuration.
