This is a neat concept for a child’s first bike; don’t know how well it actually performs.
When I was little I don’t think I had the best experience with training wheels. They may not have been properly configured. It seemed to take me longer than usual to get the hang of riding and lose the trainers. Either that or I had a bad sense of balance and want to blame it on the training wheels. Ha. Anyway, I seem to have overcome the slow start.
