The Sierra bike is designed to be our best 18" bike. From a replication of the Sergio Layos signature frame just adapted to fit perfectly on 7 to 12 year old riders with the full range of supported bike parts to get a complete top-range 18’’ machine straight out of the box.

Note: LHD (Left-Hand Drive) and RHD (Right-Hand Drive) refer to the side where the drivetrain is located to protect your chain & sprocket when you grind.
