This is very familiar to me. My son turned 5 in August, I just taught him to ride a bicycle. He was riding regular and modified power wheels when he was 2 and riding his four wheelers since 3. We experienced the same dilemma trying to get him to ride a bicycle, he only want to ride his four wheelers. I started to make him practice his bicycle every day before I would start his four wheeler. It didn’t take long for him to learn the bicycle, and now he likes riding it.
I usually had such old POS cars that required moving the dimmer switch up to the dash. Never had a dimmer switch stick on (or worse still, lights go out completely) again.
Another candy company bought them when they closed & are supposed to start making them again this fall. I’m ever hopeful.
