Even with the crank or pedals removed, a 12" pedal bike is (usually) too tall until a kid is 3 and a 16" bike til four. Although newer premium bikes like Cleary can sit lower. A good balance bike can be ridden at 2yo. A Strider brand can be ridden at 1.5 if your grandkid is precocious. But my Kid 1 didn't get the idea til 2yo, good enough until 2.5yo, and by 3yo he needed brakes and air tires. So Twins 2A and 2B got bigger balance bikes. Muna, specifically, though there are tons of other options.
This is not ragging on the Strider, I think it's a great design. Especially the second-level version with the bigger seat and quick release clamps. My kid rode his all over. It can be upgraded with air tires too. But it needs a hand brake and a longer wheelbase for a kid over 3.
