I am happy on 18/11/2018, both my kids Deef & Lish can ride 2 wheel bicycle.
Deef persistent by keep trying, less talking and focus on learning making him able to cycle 2 wheels quite fast. Within 2-3 weeks, he was able to ride on 2 wheels.
Lish talked more than trying to ride and overthink made her learning longer than Deef. When she saw Deef successfully rides 2 wheels she started to focus and trying more.
Lish never give up attitude even after suffered few bruises made her success more sweet.
