hey, they will hold u, yes but if they run well with u on is the question, they are designed for little kids, mi lil bro has a 50cc dirtbike & he is only 9 & 50cc can handle his 25 kgs of weight, maximum weight means the maximum weight it will hold before it breaks, that doesn't mean you will go over 10 km per hour. it may last a day but i wouldn't bother. maybe get like 110cc ones or stuff
