Yesterday I went biking with my niece (who is just a few weeks without her training wheels). IT was interesting.
Last year someone down the street was throwing out their kids bike. So i took it. So now my niece can ride with me.
She can now start on her own. And more or less stop. Only issue is her steering. She can't really stay straight in a very small area.
So no bike path yet. She could do it as long as there were no other bikes on the path.

(not sure how she would get out of the way).
So we just went around the block and close by. At first i was going to just jog beside her. But I was feeling a bit under the weather and it was too hard to run beside her. The bike thing worked out well. I could stay in the middle of the street to make sure no cars got near her. And surprisingly even though we were out for an hour it didn't take much energy. Even though i was always pedalling. I wasn't going fast.
