The Yoof 20 has been designed from the ground up specifically to suit the smaller rider thats not quite big enough for a regular 20 BMX but a bit too big for a bike with 18 wheels. The Yoof 20 features a smaller frame, bars and cranks to best fit the smaller rider. This BMX also benefits from a forged 1 piece crankset, 25t-9t gearing, a 9t cassette hub and a low stand over height.
