The bike that Longsjo often referred to as his "truck" was a Schwinn Paramount, according to Peter Nye's book, "Hearts of Lions" (p. 176). Considering the poor shape the bike was in at the time, it was probably one that had been built in the late 1940s by Oscar "Okky" Wastyn or Ovie Jenson.
He used this bike to win the Massachusetts State Championship in 1953, winning all 3 events on offer.
This was his first bike race, by the way.
His second race was the National Championships, in which he placed 9th, again on his old Paramount.
His third race was the New England Track Championships, winning all 4 events on offer.
Longsjo shaved his legs, by the way.
He won the Quebec-Montreal road race in 1954, winning $300 under the table and a new road racing bike. The book doesn't say what this new bike was.
However, after Longsjo won the Canadian National Championship road race in 1955, he was recruited by Fioro Baggio to ride for the Baggio-Torpado team, so at that point he was (obviously) riding a Torpado.
When Longsjo raced in the 1956 Summer Olympics, in Melbourne, the US Olympic team bikes were Schwinn Paramounts, so presumably that's what he rode then.
After the Olympics, before his tragic death in 1958 (not 1956), he continued to ride for Baggio-Torpado ... on Torpado bicycles, of course.
