KINK ROASTER 12" BMX BIKE 2026 ASTRO RED

The Kink Roaster is designed to be a child’s first BMX bike. Its 12” wheels and frame make it just the right size for children to feel completely comfortable on their first pedalling bike.

This bike factors in standard BMX geometry and adapts them to a child’s needs. The Roaster also features a coaster brake in lieu of a lever-based brake system, that could be too difficult for some children to use at a young age. The Astro Red colour really pops and adds to the fun ride.

Note: Designed for children ages 4 and up. Seat height adjustable from 15.5"-18.5".
