Perry Kramer PK Ripper 27.5"


When the original PK Ripper burst onto the scene in 1979, it took the BMX world by storm & set a new benchmark for radness. Here we are 40+ years later and it’s happened again with the PK Ripper 27.5, designed by the man himself, the PK of “PK Ripper”, Perry Kramer. This ultra-cool bike features tubeless ready 27.5” x 2.5” Vee Speedster tires, sealed internal headset, internal cable routing, Tektro hydraulic disc brakes, Oakley B-1B grips, and of course Perry’s stamp of approval. This is the PK of the future!

Absolutely awesome bike but...

I love this bike. I feel like I'm back in my teenage years every time I look at and ride the bike. My rear brakes are a little noisy which is resolved easily by adjusting them, but I find I have to do this every ride. Not a biggy! My son and I drove from Chicago to Boulder this past summer. We took our bikes. Somewhere along the trip, our bikes "kissed" and my PK is the one that suffered some paint scratches and stickers gouged. I emailed SE and found that we cannot purchase the stickers or touch-up paint. The paint is no biggie, but the sticker situation bums me out. I wish SE would make these available. Other than that, you can't go wrong with this bike. I'm on the heavier side, and the bike is sturdy and smooth!

Perfect 275

Owned many BMX bikes over the years and this one takes the cake by far! #Sebikelife #pkripper27.5


This bad boy is so awesome! Had my PK stolen when I was a kid so this is my gift to myself

Jeff Mirka
It's a awesome bike!

This bike is awesome, I love all of the details on the bike. 27.5 seems to be the perfect fit. It fits perfectly into my heard of SE's! Get outside and ride!

Bad Ass Ride

I grew up in the 80's racing bmx's locally in my small town. I had a Kuwahara but dreamed of some day owning a PK Ripper. Finally made the dream reality with a PK 27.5! I am so happy with this bike. Rides like a dream. I can't wait to buy another SE bike, possibly a quad or fasty. Highly recommend the PK Ripper 27.5
