Question: how long is this board?
Document: My 5 yr old son is an advanced skater for his age (He can make it up and down all transitions and ramps and even some of the bowls/ pools in a skatepark). Before buying this Powell board, he was skating on a Walmart Spider-man board which was a little smaller. 28/ 7.5. My concern was that the Powell 31/ 7.6 might be a little too long for him to maintain his control in the park.
The other thing about the board is that for an 8 year old it is long and heavy to carry and the wheels are pretty hard for going over the crummy broken Minnesota sidewalks on the way to the park to practice. At one point he dropped it because it is just too awkward for a small kid to lug around. It kind of ruins your rep when your mom has to carry your board. If we do get him a smaller board we'll keep this one till he grows into it.
He is easily frustrated so his turn on the board didn't last long, so I took it out for a test ride. This board is prettier, sturdier and better-constructed than any board I ever owned (my first board was an inch thick and had clay wheels, for what that's worth), and much less expensive. The deck is concave and completely covered with grip tape, the trucks are firm and the wheels spin freely. (It also comes with a bonus instructional DVD.)
It was too long for my son. Was surprised by the quality in it, but unfortunately it didn't fit. :(
bought for my son 15 who loves it... for the price you cant beat it. I will let you know how long it last as he just got this for Christmas
My son picked this out himself for his birthday and loves it. Most other cheaper boards I have purchased don't hold up long, this one is still going strong. I didn't even notice when ordering that it came with a DVD with some tips and tricks. That came in handy seeing as it's been 22 yrs since I &#34;popped an ollie&#34;....and I think I fell on my face =P
All in all, it was a very good board for the price.
!Overall, very happy with my board and my 6 years old girls love it too! !
