Frogman’s Rocket 3

Photos of the Decoson and the Rocket 3 by Randy Johnson

Randy Grubb has been ranked among the top 15 U.S. fabricators by Hot Rod Magazine. He built Jay Leno’s Tank Car, the Indy Special, the B-702, Piss’d Off Pete, the DecoLiner (the coolest combination of art deco with an RV that we’ve ever seen), the DecoPods, and the body for the Bob Maddox Pulse Jet Lakester.

Then Grubb got a call from his English pal, Tim “The Frogman” Cotterill, famous for his bronze sculptures of frogs, hawks, and owls. The Frog had designed a powerful, ultra-sleek machine with animal-like qualities that he called the Rocket 3. “It combines my love of choppers, trikes, hot rods, and dragsters,” Frog said, and then he asked Randy to team up with him to build it.

Earlier, the Frogman had built the Rocket 1, a trike he made famous in England. Next, after he moved to Venice, California, Frog built the muscular 1,000 horsepower blown Hemi Rocket 2. This monster does 0-100 in less than 5 seconds, with a top end of 200 mph!

From mind to metal, now witness Randy’ Grubb’s complete build of Cotterill’s Rocket 3. Its rear suspension is beautiful, cool, and crazy; it flexes just like a big cat on the run. And with its 430 horsepower Corvette engine, the Rocket 3 will scram, doing 0-60 in less than 4 seconds.

The basic concept for the Decopods and the Decoson was born in 2012 when Randy was sitting on his buck for the fender of the B-702 and wondered why the form couldn’t be a motorcycle. In a conversation with Don Tippit, Don started talking about old scooters like the Cushman and the vintage late ‘40s Salsbury Model 85 scooter, and Randy’s imagination was sparked by his memory of the 1934 Art Deco Streamed Henderson motorcycle. From that brainstorm, the Decopod was born: a fully functional—and fun— way to cruise down the highway in a motorcycle with doors. The idea of riding on the outside of the streamlined form evolved into Randy’s Decoson motorcycle. It was built in 2013 on a 1984 Sportster chassis.

The tapered bullet-like, polished aluminum Decoson won 2nd in the Custom/Modified category at the 5th Annual Quail Motorcycle Gathering in Carmel, California, in 2013. It is now on permanent display at Northwest Harley-Davidson in Lacey, Washington.
