Hi all, I am looking for a different set of handle bars for my 6 year old on our childback Tandem. The current ones mean she needs to stretch down too far so looking for the bars I have seen on other versions of the same bike that curve around more enabling a more upright position until she grows a bit. What should I be searching for to find these bars online? I have hopefully attached a picture of the present bars - the yellow ones. Plus the type I am looking for. Many thanks
