Great for kiddos who are old enough for the “big kid” seat on the rear rack, but are easily distracted or take naps on the ride. The Adjustable Monkey Bars are compatible with the Yepp Maxi child seat and most of our other Add-Ons. The new adjustable design allows more versatility with your rear rack. With the easy-to-use snap pin attachment system the bars can come and go as quickly as your cargo changes. This new feature also makes storing your cargo bike in a tight space much easier.
