GT knows that little groms go big, too, so they built the El Centro 18. It features a fine GT steel frame and fork for kid-approved park- and street-worthy toughness. And, this sweet rig is ready for the air with burly Alex rims, and stout 3-piece tubular-chromoly GT cranks. Plus, the El Centro is as versatile as the big bikes with a pair of grind pegs and an SST Oryg cable detangler for all the freestyle action you can throw down.
