I would just like to share some information I have regarding cup holders for Bugaoo's. I have owned a Mamas and Papas P3 for many years and have often had people come over to me and ask where I got my cup holder from and they have always been disappointed when I tell them it comes with the pushchair.
I have discovered that these Mamas and Papas P3 cup holders fit onto the Bugaboo frame.
They can be purchased off of ebay (search under Mamas and Papas) or I believe direct from Mamas and Papas spare parts.
I hope some of you fellow Bugaboo owners find this information helpful.
