Nicolas has been able to balance on this bike for a while, so we took the training wheels off sometime last year.
However, he could not get himself to start or stop the bike on his own. He would just get frustrated with it. In his defense, this bike really is heavier than most kids' bikes and that doesn't help matters. Either way, I bribed him $5 to learn to ride on his own on this beautiful sunny day and he did just that. He's now officially a bike rider, though he's still a bit wobbly.
