I'm 6 foot 3 and weight around 13 stone, and those slightly cheaper junior boards they sell are not for me. I went for the senior longboard. The junior boards fit their namesake. With a smaller power motor their performance is suited to a smaller lighter person.
You'll see the longboard is not small and definitely dwarfs you average manual skateboard. But, being a longboard its sure easy to ride. See below for the exact specs (I lifted this straight from the VoLo-e ebay shop - it was blurry there too!).
