Mongoose: July 1977 – March 1982 As the biggest, fastest cruiser rider in the world . Jeff would line up on the starting line everyone else would try and figure out who was going to get second, in 1980 Jef won 21 out of 24 Nationals the ABA national #1 and the NBA national #1 and the JAG World Championship in the same year. To this day there is not more of a demonating year in the sport by one rider. The Kos Kruiser is the most winning bike of all time. According to Kosmala Mongoose wasn't going to pay him for his name on the Kos Kruiser which he was owed, it cost mongoose a lot more than Jeff was asking for.
Redline Engineering: Early April 1982 – Early May 1983 Jeff took his talent to Redline Eng, where he designed and raced the "redline PL-24 " which he stayed on his winning ways. His first race for Redline was the NBL Detroit, Michigan National on April 17, 1982. He won Pro Cruiser. In the middle of the summer of 83 Jeff and his long-time girlfriend got married and he decided to hang up the bars.
O'Neal: January 1984 — Kosmala got back into the BMX world by becoming a sales representative for O'Neal, a Motorcycle Motocross apperal company which was trying to break into the BMX market. Kosmala would occasionally race in O'Neal livery much like John George did for Mongoose after his retirement from competitive racing.
