Adrian has alternated between walking to school, and taking his scooter. Now he’s rediscovered cycling.

His is the tiniest bike in the school. By all objective measures, it is too small for him. But purely subjectively, he feels comfortable on it, even if his knees almost hit the handlebar. He doesn’t feel comfortable on a larger bike because he is too far up – it’s a long way down.

One benefit of having a tiny bike is that he can carry it up the stairs himself, when he has to.
