| Fit and seat height | Have the child sit on the bike while wearing usual riding shoes. Check that the seat can be adjusted to suit their inseam. | The child can place both feet flat on the ground with a slight bend in the knees and can get on and off comfortably. | The child can reach only with tiptoes, has to stretch to reach the ground, or appears cramped. |
| Brakes | If fitted, inspect the brake lever, cable, and brake mechanism. Squeeze the lever and gently roll the bike forward to confirm that the brake slows or stops the wheel. | The lever moves smoothly, is reachable by the child, and the brake engages reliably without the lever touching the handlebar. | The brake does not engage, drags when released, has a frayed or loose cable, or the lever is too large or stiff for the child. Some balance bikes have no brake; check how the model is intended to be stopped. |
| Steering and handlebar | Turn the handlebar fully from side to side while the front wheel is off the ground, then check it for looseness and alignment. | Steering turns smoothly without catching, excessive play, or unusual noise. The handlebar stays secure and lines up with the front wheel. | The steering binds, rattles, slips out of alignment, or has loose fasteners. A steering limiter, if fitted, should work as designed and should not interfere with normal control. |
| Frame and fork | Look over the frame, fork, and joints for cracks, bends, sharp edges, and loose connections. Check that the front and rear wheels sit straight. | Parts appear undamaged, joints are secure, and the frame and fork do not shift or flex unusually during a gentle stationary check. | Visible cracks, bent parts, exposed sharp edges, loose joints, or wheels that appear misaligned. |
| Wheels and tires | Spin each wheel and check for rubbing, wobble, damaged tires, and loose wheel fasteners. Inflate pneumatic tires to the pressure shown on the tire or in the instructions. | Wheels rotate freely, are securely attached, and tires have no cuts or significant wear. Solid tires should be firmly seated and undamaged. | A wheel rubs the frame or fork, wobbles noticeably, has loose fasteners, or a tire is flat, split, or badly worn. |
| Seat, seat post, and grips | Check that the seat post is inserted at least to its minimum-insertion mark, if marked, and that the seat and handlebar grips cannot twist or slide by hand. | The seat and grips are secure, comfortable to hold, and free of tears or exposed hard edges. | The seat post is above its minimum-insertion mark, the seat shifts, grips slip, or there are sharp edges or loose end caps. |
| Fasteners and moving parts | Check visible bolts, nuts, and clamps before each ride. Tighten them according to the manufacturer’s instructions and torque values where provided. | Fasteners are present and secure; wheels, steering, and seat remain stable during a gentle check. | Missing, loose, damaged, or mismatched fasteners, or any part that shifts during use. |
| Safety features and setup | Check for smooth, covered edges; secure handlebar ends; and any reflectors or other safety features included with the bike. Assemble and maintain it according to its instructions. | The bike has no obvious pinch points or protruding sharp parts, and all supplied safety components are installed securely. | Missing parts, exposed sharp edges, loose accessories, or assembly that differs from the instructions. |
| Pre-ride safety | Before each ride, do a quick check of brakes (if fitted), steering, wheels, seat, and fasteners. Have the child wear a correctly fitted bicycle helmet and ride in a clear, suitable area with adult supervision. | The bike is in working order, the helmet sits level and is securely fastened, and the riding area is free of traffic and major obstacles. | Any defect affects steering, braking, or stability; the helmet is damaged or loose; or the riding area is unsafe. |
