A Street Statement. A Performance Weapon. A Killer Ride.

This isnt just a bike. This is SE’s loudest, wildest, and most unapologetically rad ride yet. The Killer Quad 27.5 blends BMX legacy with modern performance in a package so bold it turns pavement into a runway. With a signature Quad frame design, massive 27.5 x 2.5 Speedster tires, Tektro hydraulic disc brakes, and a smooth-shifting microSHIFT XLE 1×10 drivetrain, this bike is as fast as it is ferocious.

Whether you’re riding urban, smashing hills, or leading the pack at the rideout, the Killer Quads style and power will make sure all eyes are on you. The Electric Aqua Marine finish? Let’s just say, if confidence were a colorthis would be it.
