I put a lot of time and way over thought this purchase, and was still surprised at how good this bike is.
As an engineer, I have an appreciation for build quality and design that I gained from work experiences. This bike does not disappoint, it's clear that the design and engineering was thought out, and manufacturing processes are well controlled.
My son jumped on it took off immediately. He was using a $5 Goodwill Huffy before, to get a taste for pedals, and he was clearly more stable, confident and comfortable on this right away. I was surprised at how noticeable it was.
The only adjustment I've made is to bring in the brake lever a little to better match my sons grip.
