My son loves this bag. It’sa bit snug to wear as a backpack (he is an average 5 year old), but it’s perfect on his scooter or looped over his bike handle bars. It helps him be responsible for his belongings when we go on walks and is big enough to hold a small hydroflask and a few other items (sunglasses, notebook, small toys). This was a great purchase and its good quality. It will also work on generic scooters - we got one for our friends and it fits their child’s scooter just fine.
MINI MICRO RUCKSACK is a fantastic addition to the Micro Scooter! My 4 Years Old Absolutely loves it. He carries all his little toys, sunglasses, water bottle in the Micro Rucksack for all his rides.
