Yes my son now can ride a 2-wheeler!
It took quite long to persuade him though to switch from a four-wheeler to a two-wheeler. He was excited when we bought him his 1st two-wheeler, but after a few attempts and one nearly hitting a wall incident, he was discouraged and did not want to get back on the two-wheeler again.
However, with constant encouragement and motivation, he somehow managed to overcome his doubts and gave it a try again! And he did it!
Yes, no doubt, he is not 100% steady, but the fact that he is trying and improving tremendously and becoming more confident, I am so proud of him!
