Did you know that the Primer 18 Complete bike has the shortest chain stay length of all other 18″ BMX bikes on the market today? It’s chain stay measures 11.75″ which is 0.5-1.5″ shorter than all the other brands. This is a HUGE difference to a 10-13 year old.
The chain stay length is measured from the center of the crank spindle to the center of the axle of the rear wheel. This isn’t a standardize measurement and can vary greatly from brand to brand. Over the past 10 years, the lengths have been getting shorter and shorter on 20″ BMX bikes. The short chain stay length makes it easier to lift the front end when jumping and bunnyhopping. A bike that is more maneuverable is more fun and easier to learn on. Choose Wisely!
