The Ammaco Grime BMX Bike had the best balance of style and practicality,with its Freecoaster hub allowing the rider to go backwards without having to back pedal like a typical cassette or freewheel hub, opening up a whole new world of trick possibilities. The 9 Teeth Driver (COG) with 25 Teeth chain ring makes it perfect for street & skatepark fun, the U-brake on the rear gives great control when needed
