Absolutely not. I would also get the children a balance bike so that they can ride a bike within a short time.

No, it can not. The FollowMe, as the name implies, is follwing the lead bicycle in direction and angle.
My advice would be, get rid of the training wheels and get an Early Rider Big Foot Balance bike... Your kids will learn much faster

Non

The bike on the Follow Me leans with the same angle as the larger bike. It would seem impossible and incredibly dangerous to put a bike on on it with training wheels.
