About this item

• 【3MM THICKENED ANTI-BEND STEEL BRACKET】Engineered for maximum rider safety, our support arms are forged from 3mm thickened, heavy-gauge carbon steel—20% thicker than ordinary brackets. Specially reinforced to resist bending, cracking, or warping during rough rides and accidental tumbles, reliably supporting young riders up to 120+ lbs with rock-solid stability.
• 【UNIVERSAL ADJUSTABLE FIT FOR 12" TO 20" BIKES】Designed with a multi-hole vertical adjustment track, these bicycle stabilizers seamlessly adapt to 12, 14, 16, 18, and 20-inch single-speed kids' bikes. Easily customize the wheel height off the ground as your child progresses from a hesitant beginner to a confident, balanced two-wheel cyclist.
• 【ANTI-SLIP & MUTE GROOVED RUBBER TIRES】Featuring high-grade, wear-resistant rubber outer tires with deep anti-skid grooved treads, these training wheels provide superior traction and grip on asphalt, concrete, sidewalks, and packed dirt. The shock-absorbing rubber rim ensures a whisper-quiet, smooth ride without annoying plastic rattling or indoor floor scratching.
• 【SINGLE-SPEED COMPATIBILITY & FIT CHECK】Specifically engineered to fit standard single-speed children's bicycles with traditional rear horizontal dropouts. (IMPORTANT: Please ensure your rear wheel axle has at least 0.4 inches / 10 mm of visible exposed thread for safe mounting. Not compatible with multi-speed bikes equipped with rear derailleurs).
• 【COMPLETE EASY-INSTALLATION HARDWARE KIT】Comes fully equipped with all necessary mounting accessories: 2 x heavy-duty grooved wheels, 2 x 3mm vertical steel brackets, 2 x shoulder bolts, 2 x locking nuts, 2 x anti-rotation limit plates, and washers. Simple step-by-step instructions allow you to complete a sturdy, wobble-free installation in under 10 minutes.
