Foot power vs. Horse power?

Who needs a pedal bike when you have access to horse powered machinery?! Surely not Aiden! Davids friend Daniel has boys who use to race "real" bikes....the ones with motors, and they were nice enough to let Aiden get his feet wet with this little 4 wheeler. David can adjust it to a max speed, which has proven to be a good tool!! Once little Kanevil figured it all out, it was ALL GO from then on!
Aiden likes to race hid dad....and dad usually lets him win! I am afraid that we have opened the flood gates to speed with this little contraption! Aiden no longer has much interest for his "fastest bike ever" he now refers to it as the "slow, slow bike!"

Aiden would love to spend hours riding around the yard, but after about an hour his thumb gets tired from holding the throttle!

The boys have fun zipping around the yard, and the dog gets dizzy from all the chasing he does! I
am sure that this will not be the last 4 wheeler for Mr. Dude!
