Precaliber 20 Coaster Brake will have your little rider begging to go out for a pedal on their first real big kid bike. It's a great transition model from training wheels. It has one speed, a coaster brake, and a saddle with an integrated handle that can be swapped out for a light mount. For kids ages 6-8, between 45-52˝ tall.
