Query: Must be for giants.

I bought this for my nephew who is 5' 7" since he rides a 26or27 inch bike. After placing the seat all the way down, I still had to hack off about 6 inches of the seat bar. At 5'11" I still can reach the pedal at the bottom even with the seat in the lowest position. I may be new to unicycles, but even I can figure out it helps to be able to reach the pedals. Overall construction does seem sturdy though, so if I can get the darn thing sized, maybe we can start enjoying it.
