It's never too early to get your child started learning to ride a bike. Kids as young as two learn fast on a toddler bike with no pedals.
These toddler bikes from Strider, Glide Bikes and Smart Gear cater to the youngest of riders. The bikes generally weigh half the weight of a conventional bike, so kids have an easy time maneuvering and controlling the bikes. Most toddlers will start out simply walking the bike around, but its not long before they begin to get the feel for balancing on the bike and before you know it they're off and riding.
Toddler bikes are safer than tricycles and bicycles with training wheels which can tip over easily. Since these bikes sit low to the ground, kids can easily lower them to the ground when they lose control with little risk of injury.
You'll be amazed at the progress you see from your toddler as they explore their ability to balance and master the motor skills needed to ride a pedal bike. Expect them to stick with the balance bike for a long time. Since it's so light and easy to maneuver, kids can take it in the grass, up hills and anywhere else they want to go making it a fun toy your son or daughter will enjoy for years.
