With a name like Gravity, you’d hope that the FSX Mountain Bike will keep its tires firmly on the ground when you need a sure grip – but at the same time allow you to fly through the air as you jump over rocks and other immovable objects.

It does all of that and more as you are about to find out.

2021 Gravity FSX 29 LTD Dual Suspension 21 Speed Mountain Bike

41zHlvmcpAL. SL500

Gravity is not a brand which many cycling fans would regard as one of the top echelons.

As we always say, the brand is irrelevant if the product delivers quality at an affordable price. That is precisely what the 2021 Gravity FSX Mountain Bike offers, and is the reason it is so popular and sells in the numbers that it does.

It may not be a top brand, but it uses some of the industry’s top names for the components used – such as the Tektro brakes and the Suntour suspension. These, coupled with a price lower than most mountain bikes of this standard, make it an excellent choice.

Who is This Product For?

The Gravity FSX is most suited to males whose height is between 5 feet 2 inches and 6 feet, with a frame size of 17 inches, and with the frame design as it is.

As it is from a less-known brand, it may not appeal to serious mountain bikers who want only a top brand. Still, for those for whom mountain biking is a hobby, or those looking for their very first mountain bike, this is an excellent option.

It is priced low enough that you could consider buying it as a gift for someone keen on mountain biking or wanting to try it.

What’s Included?

Very rarely will you get a mountain bike that is fully assembled if you order it online. The Gravity FSX is no exception, so expect to receive a box with the bike’s components inside.

The frame with the rear wheel will be the largest segment, accompanied by the handlebars, front wheel, seat, and pedals. You will also receive the instruction manual.

Overview of Features

The Gravity 2020 FSX has a durable but lightweight aluminum frame, which makes it ideal for the terrains it is likely to be going on as it provides strength and maneuverability at the same time.

The Suntour suspension, from a top manufacturer of front and rear suspension units, provides a level of comfort and also protection for the joints in your arms.

Tektro dual disc brakes can be found on the front and the back. You will know that whenever you have to stop suddenly, you can rely on them to bring you to a swift halt.

Finally, and arguably most impressive of all, are the gear speeds. The Gravity FSX has no fewer than 24 options provided by the Shimano front derailleur, which has three gears, and the rear derailleur, which has 8 selections, giving a grand total of 24.

How to Use It

The Gravity FSX is relatively easy to assemble, but not everyone will want to go through the process. You might choose to take it to a local bicycle store, where they usually have an on-site bike assembly service.

It will obviously cost, but it is not much. It also means you can be assured everything has been assembled correctly.

If you are going to assemble it yourself, you will need a few tools – an adjustable wrench, a Phillips screwdriver, Allen keys, and pliers.


  • Disc brakes on front and rear
  • Aluminum frame
  • Excellent value for money

Schwinn Sidewinder Mountain Bike

Suppose you are looking for a women’s mountain bike that offers every bit as much value as the Gravity FSX. In that case, a great option you should consider is the Schwinn Sidewinder Mountain Bike.

It will not break the bank, and given that it is made by Schwinn, you can be assured that it is a top-quality bike. It includes 21 gear speeds, disc brakes in the front and rear, and a lightweight aluminum frame.


It may not be made by one of the top mountain bike brands, but the Gravity FSX is a mountain bike that holds its own next to them. It offers plenty of features and a mountain biking experience that is worth every cent.
