Question: I bought this bike in June but my tire is flat now. How to buy only a tire  for this bike? Thanks
Document: Love this bike but I bought mine at walmart for $100 less and already put together
The bike arrived quickly. It wasn't too hard to put together once I found the right tools. Rides nice, my daughter loves it
The bike is not very comfortable and it feels very cheap. It took a while to put together too. It looks cute though
I love it! It was inexpensive and looks great! I haven't gotten to ride it much since the weather hasn't been great but my initial voyage was awesome! !
Not only is it pretty, it was easy to put together and it was an easy ride. Already got a lot of miles on it.
It was just as pretty as the pictures and put it together easily. Loved it more than time can tell
Answer: no
