The event is a three-day party and fundraiser put on by Bob Parsons, founder of GoDaddy and owner of the Harley Davidson shop in Scottsdale.
All proceeds from tickets, food and beverages go toward supporting Phoenix Children's Hospital. Parsons hopes to raise $100,000 this year.
"Phoenix Children's is a great local organization and we're all about helping children," Parsons said.
The event features a bikini contest, live music, food and drinks, simulators for riding motorcycles, and a motorcycle giveaway.
If you have a motorcycle endorsement on your driver's license, the concert is free, otherwise it is a $20 donation. All other activities at Bob's Biker Blast are free.
Bob's Biker Blast kicks off Friday at 4 p.m.and runs through Sunday, Oct. 13.
