Resurrecting this thread, because I'm sure we all need a good shot of good news right now..
Started out with the woom balance bike on 2nd birthday. Christmas 2020, we upgraded to the woom 2. He used it like a balance bike for the following year until this past Christmas. Sometimes he would try to pedal... but could never really sustain it.. easily frustrated etc.
Christmas eve he made a huge leap forward and actually would pedal for short distances.. but also had periods of frustration where he wouldn't try... and just coasted around..
This week, it finally clicked. So much so that now we have to take our own bikes to really keep up with him.
not even 4 1/2 years old, and never had training wheels/stabilizers.
