Boys and their Bikes

Kail has learned to ride his bike without training wheels in just two days.  He started to learn when hubz took off the pedal on his bike so he can balance.  A day later, he can ride with his feet up!  Now he can ride fast and longer distance without training wheels.  Here's the evidence:

Calix is also starting to put his feet up so we think it's just a matter of time and he can probably ride without training wheels as well:

If I could only learn to do the same... :)
