Little sister made a breakthrough in balance riding on her Strider bike tonight. In the last few weeks, she's gone from walking her bike along, to running her bike along, and recently started lifting both legs simultaneously for just a half second as little self-tests of her courage. But during our evening ride today, she discovered she could lift both legs and coast. It seems she's over the crux and just about has this balance bike thing figured out. I predict more speed and coasting in the immediate future.
