The Colony Cadet 18” BMX Frame is built specifically for smaller riders who need a high-quality frame that doesn't compromise on quality. With its 18” toptube and geometry scaled perfectly for 18” wheels, the Cadet 18” delivers the same proven strength, handling, and versatility as its 20” counterpart, just in a smaller, young rider-friendly package. Designed with a progressive all-round geometry, the Cadet 18" is ideal for park, street, or general riding. Built from 100% full Chromoly tubing, it features tapered toptube, downtube, and rear stays, offering a solid balance of strength and weight. All the critical stress points, integrated head tube, mid bottom bracket, and 6mm thick dropouts, are heat-treated for maximum durability, while integrated chain tensioners make rear wheel setup easy and secure. Clean and functional design is at the heart of the Cadet, with details like external gusset on the downtube for added strength, an integrated seat clamp, and removable brake mounts complete with Colony’s exclusive invest-cast removable cable tabs for a clean, brake-free look if you choose to go brakeless. Whether you're a younger rider or need a more compact setup, the Colony Cadet 18” frame brings top-tier quality, geometry, and design to the smaller wheel size, helping you build confidence and push your riding further.
