I bought this for my son for his second birthday. He loved it from day one. By the time he reached his third birthday he had worn out the wheel bearings completely. So reluctantly we bought him a different new bike for his third birthday and he didn't want his new bike, he wanted his fast bike. We replaced the wheel bearings and at 3 1/2 he still rides his fast bike and we've had to replace the wheel bearings again from excessive use while his new bike sits neglected! I'd like to add he has such great balance he can now ride a gas powered dirt bike by himself with no training wheels.
