The PK Ripper was the raddest, baddest, and most famous bike during the first BMX boom in the early 80s. Fast forward 40 years to today and now its the 29" Big Ripper that's on top during the Big Bike BMX boom. This Big Ripper frame comes equipped with an American bottom bracket and an OG seatstay wishbone plate just like the original PK Ripper. The 29" x 2.4" SE Bozack tires are just wide enough to give stability and cushion, but also roll extremely fast. Whether you are an old school BMX rider reliving your youth or a new school SE bike life rider raising it up, the Big Ripper is for you.
