It's one thing to teach a child how to ride a bike, it's another to make sure that they're following specific safety instructions in the process. An easy way to reinforce your lessons is with a fun educational activity, like "Practice Bike Safety". These coloring books can be customized with a screen print with your information. Each one is 16 pages, plus cover. The body is made from 5 pt. bulky newsprint, with a cover made of 50lb offset.
