My daughter has been given for your bike this bag and is very happy with it - now they can transprotieren all their trifles with the wheel - clear, it is not too much space in your pocket - it's also a bicycle handlebar bag for children and no backpack ! At the moment I have it even on my bike :) and no longer want to miss it;)
Strong buy recommendation, since the processing is great and the bag can also be used as a shoulder bag.
