i found a '65 "union holland" bike frame that was very classic postman bicycle,the double tube inspired me to transform it in a rat bike,the only thing that was missing was a engine.so i got one,some wheels from a holland B.S.P and i built this bike in 12 hours.it's working perfect and it sounds good,the bike its big and strong and it reaches 60km/h.the youtube movie is at the first kick. click for pictures http://www.portocalamecanica.ro/va-prez ... lanul.html
