SE Bikes Big Ripper 29" 2021 - BMX Bike
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 it's the 29" Big Ripper that's on top during the Big Bike BMX boom. This year's Big Ripper frame has been redesigned with an American bottom bracket and a seatstay wishbone plate just like the OG PK Ripper. The new 29" x 2.4" SE Bozack tires really set this bike apart from the rest. Whether you are an old school BMX head reliving your youth or a new school #SEBIKESLIFE rider raising it up, the Big Ripper is the bike to have.
