Balance Bikes and Kids Bicycles A relatively new type of introductory bike to graduate to from the tricycle is the balance bicycle. No pedals to put your feet on, these are free wheeling rides that are propelled by your feet as you push forward. A great intermediary step between the tricycle and bicycle, kids can learn ride a two-wheeler at their own pace. Thes budget-friendly bikes come with all terrain tires and typically will have adjustable seats and handlebars. Age ranges are 12 months to 4 years, or a 10- 22 in. inseam. Look for lightweight quality materials and remember this is a transition bike so they’ll be graduating to a larger bike in not time, so keep an eye on the price.
