The extender

  This is an extension for a pusher handlebar. It will save the backs of tall caretakers and caretakers who use a "buggy-board" (a skateboard for a toddler that clicks onto a stroller for when you have a second child, the toddler rides on the board in front of the mothers feet). It needs to fit a variety of handlebars of different brands (needs to slide out to different sizes and have attachments that fit a range of handlebar sizes), needs to be lightweight (so as not to affect the stability), needs to be sturdy (to go up sidewalks the mother must be able to lean on it and lift the front of the stroller), must be easy to take off (so you can still fold the stroller).
