Awaken Your Inner Child With Razor’s Adult-Sized Crazy Cart XL

Growing up doesn’t make go-karts any less fun

You no longer have to look on with intense jealousy as your kid zips around on his or her child-sized go-kart without you. Meet the Crazy Cart XL, Razor's solution to every adult's "inner child syndrome." With a 500-watt motor, the electric Crazy Cart XL can hold up to 240 pounds and reach a top speed of 17 miles per hour. Pair it with Razor's smaller Crazy Cart and the tot-toting Lil' Crazy, and the whole family can take to the streets, making all your neighbors green with envy. Watch Katie Linendoll take the Crazy Cart XL on a spin throughout Toy Fair 2015, almost running over a few attendees along the way.
