Core Features

Front and Rear Suspension

As a full-suspension bike, the FSX 1 features front and rear suspension that gives you a smooth ride on trails and other rough ground. The suspension system has an ergonomic design and placement that make riding a pleasure.

The suspension system uses the Single Pivot Technology, the simplest suspension design that makes the bike easy to maintain. Hefty riders need not worry, too, as the front suspension can take on even a heavyweight.

Mechanical Disc Brakes

Control is a crucial aspect when it comes to biking in the mountains or on rough terrains. The mechanical disc brakes of FSX 1.0 definitely give you the control you need to take on even the roughest trails. There’s nothing like the highly responsive and robust mechanical braking system to give you confidence in riding trails.

Shimano EF51 24 Speed Shifter

The FSX 1.0 bike of Gravity comes with Shimano EF51 24 Speed Shifter. This easy-to-use shifter gives you a smoother and more comfortable ride. The 24 speeds allow you to go as fast or as slow as you like, and to change gears at a moment’s notice.

The comprehensive gear system, inclusive of Shimano components, crank, and cassette, is made with durable Suntour parts, making the mountain bike worth it for less than $500.


This sturdy mountain bike has simple road tires that are unfortunately not suitable to handle rough mountain trails and uneven terrains. These are better replaced with mountain bike tires. This is the only major drawback of the bike. Thus, when you buy a Gravity FSX 1.0, replace the original tires with stronger ones that are suitable for riding on mountainous paths.

Double Wall Wheels

The FSX 1.0 features quick-release double wall wheels. The outer wall makes it stronger, while the inner wall protects the spokes. The double-wall does add some extra weight to the bike. However, this bike only weighs 26 pounds, so the added weight is worth it given these extra features that make the wheels stronger and more durable.
