The Jamaica Original 2C by Wildcat is a smaller scale BMX and is mainly for tricks. The cassette that the Mini BMX by Wildcat has produces a very clean sound, has a very good very good power transfer and requires almost no maintenance. The Jamaica Original 2C bottom bracket is very easy to maintain as it consists of 3 pieces. We recommend this BMX for riders from 4 years and up. Note: The Wildcat BMX comes to you 80% assembled. You must tighten all parts before use. Mini BMXs are NOT for cycling outside on the street. They are designed for closed tracks or for fun at the skate park.
