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 that make the Quantum the most advanced QuietKat ebike.

The 750 Watt motor makes this a Class 2 electric bike.

Dropper posts

A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.

Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.

Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.

Plus-size rims and tires

Wider than standard yet narrower than fat, plus-size rims and tires hit the sweet spot in grip, stability, and speed, giving you more confidence on technical terrain. Compared to a standard tire you’ll feel grip in places you wouldn’t expect thanks to a bigger contact patch and greater rollover clearance. More air volume allows lower tire pressures which softens bumps and increases float on sand or snow. Whether you’re a novice or an expert, the benefits of plus-size tires and rims will amplify your mountain biking fun.
