seems like you can make one for between 1-2K, sort of pricey on that website, but cool.
I drove the snot out of my powerwheels bigwheels plastic trikes back in the mid 70's enough so I had holes in my rear tires from skidding out all the time on the street in front of my parents house.
Slap on a morecomfy seat and backrest on this one and good to go all over again.
