The 20″ Colony Horizon is a special stepping stone BMX bike in that it has a light weight alloy frame, shorter 18.9″ top tube length. This means it feels & rides like an 18″ bike can but has the larger 20″ wheels. This bike is designed for riders up to 12 years old only. It’s a perfect bike to enter the 20″ world, progression & having fun with BMX will come naturally, for all styles of riding, including those aspiring to be a future BMX Freestyle Olympic athlete. With the Colony Horizon series of BMX bikes, there is no limit to where BMX could be taken.
