Cycling with a toddler on a child seat, there's not much space for a backpack (I'd like her to keep her nose!). I've got a front pannier rack, so sometimes take a front pannier instead. This works well, unless there's walking to do at the other end. Even with the strap attachment, an Ortlieb pannier is rather unwieldy.
I know that convertible pannier bags exist, which convert into rucksacks. These would be absolutely perfect... if they fit on the front rack.
Does anyone have a suggestion of a convertible pannier that can be used on a front rack? Or any other clever ideas?
