Quantum mechanics is the body of scientific laws that describe the behavior of photons, electrons, and the other particles that make up the universe. The study of Quantum physics is so advanced that most of us cannot understand it, therefore anything labeled Quantum is extremely important.

The Quantum combines the most advanced technology and geometry available with 150mm of front and rear suspension travel. 4 piston hydraulic disc brakes allow you to keep control in the roughest terrain, and the 27.5” x 3” tires, aggressive frame geometry, and upgraded components are designed to climb the steepest hills and descend any terrain with confidence and performance.

The Quantum includes the Funn Package, which includes Funn handlebars, grips, stem, pedals, and a remote dropper seatpost which make the Quantum the most advanced QuietKat e-bike.

The Quantum is available in 1000 Watt and 750 Watt motor options. The 750 Watt version is a Class 2 electric bike.

The Quantum is our most traditional electric mountain bike from QuietKat and the Quantum features a twenty-seven and a half-inch by three-inch tire. 150 millimeters of front and rear suspension travel is available in 17-inch medium and 19-inch large sizes and comes in the charcoal, black and yellow colorway. 

The Quantum also includes the fun package, which has a fun handlebar in the stem, fun pedals, and of course an integrated dropper post. The Quantum comes stock with the twenty-seven and a half-inch by three-inch tire and you can run really any size you want, up to three inches wide on your tire, giving a wide range of options. Pair that with a four-piston hydraulic disc brake in 203-millimeter rotors and you've got all the confidence you need to tackle any terrain. 

The Quantum is built using the BaFang's M6 20 ultra drive motor with a torque sensor and is available in 750 and 1000 watt options. Quantum features a one by nine wide range gear set up to get you up the steepest hills.
