Dave, my thanks. My two grand daughters (one 9 months, one due Feb '16) will love them for sure. No doubt pics of the project will be posted.
Vaughn, I can only hope to live long enough and be strong enough to build the 'grown-up' version for both of these gals. I am hoping there is a gear changing system buried inside somewhere ... 18, 21, 27 speeds???? Low end torque, high end speed!!!
