Redline's Romp 18 isn't just a great introduction to freestyle BMX, it's also a blast to ride everywhere—from cruising the neighborhood to exploring features in the park. With its lightweight, lively aluminum frame, your kid will instantly feel confident maneuvering the Romp, and the durable steel fork handles imperfect landings while they're gaining confidence. Burly 3-piece chromoly cranks will be there every step of the way as Junior's skills increase, and the aluminium wheels keep weight down for quick handling and easy acceleration. Your child will fit right in with the big kids thanks to the 25/9 gearing, Monster seat/post combo, and pro-looking bars. Plus, a Tektro U-brake handles speed control to help make sure every ride is a rompin' good time.
