Nobody warns you about wheel size until you're already at the register. The SE Big Ripper comes in 29" and 27.5" — and that difference isn't just cosmetic. It changes how the bike feels under your feet, how fast it responds, and whether it actually fits the way you ride. Get this decision right before you spend your money.
A Little Background on the Big Ripper
The PK Ripper was one of the most famous bikes during the first BMX boom in the early 1980s. Fast forward to today, and the SE Big Ripper is leading the charge in the big-wheel BMX movement. SE built their reputation on rider-first design, and the Big Ripper carries that forward with a 6061 aluminum Floval frame, chromoly fork, and a looptail rear end that stays true to the original look while handling the demands of modern riding.
Both sizes share the same DNA. The difference is in how that DNA shows up when you're actually riding.
The 29" — Built for Adults Who Want to Ride Big
The 29" wheels on the Big Ripper allow adults up to and over six feet tall to ride a BMX bike as an everyday option.That's the core selling point of the 29" it's a full-size bike that doesn't ask you to fold yourself in half to ride it.
The 29" rolls fast. The SE Bozack tires are just wide enough to give stability and cushion while also rolling extremely fast.On flat ground, down the street, or cruising between spots, the larger wheel keeps momentum better than a smaller setup. Once it's rolling, it wants to keep rolling.
It's also the wheelie machine of the two. The longer wheelbase gives you a stable platform to hold a wheelie longer without the front snapping back down on you. If that's the move you're chasing, the 29" is the one.
Younger riders and grown-up BMX fans called this an ideal wheelie bike, and tires lasted a long time for riders who used it as a daily commuter.
The 27.5" — More Control, More Pop
The 27.5" is the more nimble option. The slightly smaller wheel drops the overall height of the bike, which means a lower center of gravity and quicker steering response. It reacts faster when you shift your weight, which matters a lot when you're navigating tight spaces or setting up for tricks.
The 27.5" Beast Mode Ripper runs 27.5" x 3.0" tires, and that extra tire volume cushions the ride without sacrificing agility. The result is a bike that feels planted and confidence-inspiring, especially for riders who are shorter or newer to big-wheel BMX.
The 27.5" also tends to be slightly lighter and easier to throw around, which makes it a better fit for riders who want a little more freestyle capability without giving up the big-bike aesthetic.

Either way, the SE Big Ripper delivers. The only wrong choice is the size that doesn't fit how you actually ride.
