as others stated - the seat height might be too low - or possibly the bike is a tad or even size too big … ? .. but regardless could / might work with a little fiddling ?

the size appears to be in the ballpark for a 5-10 rider .. ?

how does the length of the bike feel ?

face forward next to the bike - place your elbow on the nose of the seat and extend your arm / hand toward the front of the bike in line with the top tube

where do the end of your fingers rest ? before the stem ? … somewhere on the stem ? … on or past the handlebar ? …

( this is just a quick and dirty method to evaluate length )
