Input:
Good sturdy trike. Front tire wouldn't inflate and found inner tube defective with hole from factory. Also had major metal burr on front wheel at inner tube stem; found it (cut fringer) before inflating (or trying too!). Replacement tube was difficult to find due to uncommon size. Like I said, nice sturdy trike, but manufacturing process has poor quality control so be prepared to groom or repair right from the box if you really intend to get it. I did my own repairs so that my 3 year old grandson would have it for his birthday, otherwise I would have requested an exchange or refund. Bottom line is that he loves the trike, so it was all worth it.
