1991 Kastan Proline

Kastan Proline built by my 10-year old son.

I’ve been building Kastan’s for years, and now that my older son is 10, I thought he might want to build his own. He was totally into the idea (which is good news considering I’ve been collecting parts for eight years), so I had him build everything on it – from running the brake cable to lacing up the wheels. I provided guidance (and a little muscle with pressing in headset & BB), but he did all the other work himself. It took a few months but came out pretty rad!
