Bubba Blackwell began his career on April 26, 1998, when he jumped 20 cars in Everett, Massachusetts at Boston Harley-Davidson, breaking the 19-car record held by Evel Knievel.

The following year, on July 4, 1999, during an airing of The Tonight Show with Jay Leno, Blackwell jumped 14 buses at Del Mar Fair in California, tying the record held by Knievel,[2] who leaped 14 buses at Kings Island in 1975 (although Knievel's rear tire touched the 14th bus, his landing was successful).

But, you know, July 4th, 2001, there was not one person there, of the 35,000 that came, that wanted to take my place.The crash is featured on television series including World's Most Amazing Videos, Shockwave[6] and on the Discovery Channel's Destroyed In Seconds.

Following the Del Mar crash, Blackwell retired from jumping and limited performances to the Buell stunt show.

Blackwell planned to attempt to beat the XR-750 record again on June 12, 2010, by jumping 22 Ford Focus cars at the Rockingham Park in Salem, New Hampshire.

One of the highlights of the stunt show was Blackwell lifting the front wheel, doing a motorcycle wheelie, on his street-legal Harley-Davidson FLHTCU outfitted with the 120 cubic inch twin cam engine.

[12] Blackwell said he would follow his daredevil career with a lawn care business but kept his motorcycles and jumpsuit and may one day return.
