What Ages/Sizes can ride the 50 mini Adventure? My boy just turned 8 and is the top 1/4 in size for his classmates. not overweight, just bigger and stronger and taller than most of the kids in his class. We sold his PW50 a year ago because he was jumping it and smashing the frame and bottoming it out. The PW50 was a great stater, but short lived once he caught onto jumping and motorcross.
