Kid's BMX Bike

Small child's bmx bicycle about 1.4m long, a chunky low frame with fat faceted tyres, a straight bar with grips, a padded saddle and a rear pad; wheel knob (plain, training wheels bolted on) and a stance knob.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
