What People Are Saying

“My children love biking at Valmont with 303Dirt after school and on summer mornings. Gurion and his well-organized staff are all patient, enthusiastic, and super fun teachers who have elevated my kids’ skill sets tremendously. I trust my kids are safe, building confidence, and having a blast on their bikes when they’re biking with 303 Dirt.”

“Gurion is an amazing rider and even better teacher! My two small groms have so much fun in his bike skills class and ride fundamentally better because of him.”
