Like many kids growing up in Thunder Bay during the 1970s, Jay Miron was active in a number of sports, playing hockey, soccer, and tennis. At the age of eleven, he discovered another pastime, the sport of BMX, and he never looked back. By the early 1980s, he was developing his racing skills on one of the first tracks in the area. By the mid 1980s, his incredible trick-making abilities saw him win his first freestyle competition, setting the wheels in motion for a truly legendary BMX career that would span three decades.

Graduating from high school in 1989, he embarked upon a professional career, which would see him compete in all disciplines of the sport including Vertical, Dirt, Street, Flatland and Park. By 1990, his talents quickly caught the attention of a number of bike companies and he was signed on to ride with such teams as Wilkerson Airlines, Bully, and GT before settling in with Hoffman Bikes in 1992. Joining the Schwinn team in 1995, and becoming known as 'The Canadian Beast', he helped create their freestyle program and in 2000 began his own company, MacNeil Bikes.

Throughout his career, he proudly represented Canada at competitions around the world, claiming 6 world championship titles. In 1995, at the first ever Extreme Games, now known as the X-Games, he won gold in the Dirt event. Competing in the X-Games from 1995 to 2005, he has 9 X-Games medals to his credit.

Known as an innovator and trailblazer in the sport, he is credited with inventing over 30 BMX tricks including the double backflip and the 540 tailwhip and is known for his innovative double barspins, boomerang airs, and double backwhips. Aside from competing in BMX, he has also contributed greatly to the sport as a builder. In addition to starting his own bike company, he also developed the distribution company called Ten Pack, Chase BMX Magazine and served as the promoter of Metro Jam events, introducing thousands of people to the sport of BMX. Most recently, he was appointed to the inaugural Advisory Council of the Canadian Cycling Association.

In 2004 Ride BMX Magazine asked pro riders and members of the BMX industry to name the top five 'legends' in the sport. Not surprisingly, Jay Miron was included on that list, having been described as one of the most recognized and influential BMX riders of all time.
