Before the child uses their woom Bike, it is important to explain the functions of the bike to them to help them understand what they are about to control.  You should also always enforce helmet use, and glove use is also encouraged for additional safety.  
    Tip 1: For a quick overview of the bike, show your child how the crank works.  Simply lift the wheel and turn the pedals in front of your child before they use the bike. Then use the handbrake to stop the wheel.  Tip 2: The seat height should be adjusted so that both legs of the child can reach the ground and only the heels are slightly in the air. In other words, do not have your child flat-footed on the ground for a pedal bike, you want partial tiptoeing.  Tip 3: Be close to your child during their first bike experience. Have your hand underneath the seat and another hand on their shoulder. This temporary boost can get them riding on their own in no time. 
Now is an important moment for your child!  Even if you help the child stabilize, they must feel the ride themselves!
    Tip 1: Once the child starts to get the hang of using their bike, your guiding hands can slowly move away as they notice their own power.  Tip 2: An ideal place to practice is somewhere without too many distractions, and without too many obstacles.  Slightly-sloping ground can also be very helpful to let your child gain some momentum.
During the first riding attempts, it is key to walk beside the child to prevent a fall.  After just a few tries, the child will be eager and happy to go it alone - just make sure they have proper braking down first.
    Tip 1: Children often use their feet to stop their bike - we want them to drop this habit for proper safety.  The playful way we use our bikes to have them use their right handbrake first is by color coding the right brake green, and this matching the rear wheel brake pad.  Easy! 
The last step to independence (and an adventure on two wheels) for the child is to have them take off!  Learning this is easy once you have a few important bases covered.  
    Tip 1: Children typically have a dominant leg (the leg they naturally use to kick a soccer ball, for example!) Have the child take the dominant leg and place it on a pedal at about the 1 o'clock position. Once they push into the pedal, they can push off using the other leg that will then take hold of the other pedal. Tip 2: Alternatively, the riding can continue to be practiced with the physical; help of an adult, even having the adult hold the bike as the child begins to propel.
