Safety While Riding: When riding, the wheels will be bright, more visible, and safer in the evening or in any dark conditions. The most stable 45-degree triangular support design prevents the potential danger caused by a broken support bar. The clearance of the drive wheel from the ground must be the same on both sides to prevent falls due to unevenness. Assembly Instructions: 1. Connect the drive wheel and support bar together. First, put the bolt, drive wheels, seal, support bar, and nut together in order, then tighten them with a wrench. 2. Attach the stop block, remove the rear axle nut from the bicycle wheel, and attach the pointed horn of the stop block to the bicycle frame. 3. Depending on the bicycle wheel size, choose the appropriate hole location on the support bar. The training wheels should have a clearance of approximately 0.5 to 1 cm (1/5 to 3/5 in) from the ground. Tighten the axle nut with an adjustable wrench. Basic product information: Material: Metal, rubber Color: Black Wheel Diameter: 12 cm Applicable Range: 12-20 inch bicycles
