8 Reasons Mongoose Argus Should Be Your Next Fat Tire Mountain Bike

Generally, here are reasons why Mongoose Argus is a worthy purchase:

1. Size Variety

Mongoose Argus comes in a variety of sizes. Kids can find their ideal fat bike size by matching the wheel size with their age, height, or both, as shown below.

Wheel SizeAge (Years)Height
12 inch1-428-38 inches
14 inch3-436-40 inches
16 inch3-738-48 inches
18 inch5-942-52 inches
20 inch7-1348-60 inches
24 inch10-1556-66 inches

Adults, however, shouldn’t use the wheel size but the frame size to determine their right fat bike size, as shown below.

Frame SizeInseamHeight
Small (15”)31-32”4’8”-5’1”
Medium (17”)32-35”5’2”-5’8”
Large (19”)35-36”5’9”-6’2”

2. Strong and Durable Build

Mongoose picks steel for its entry Argus and aluminum for its high-end options because of their rich strength, fatigue resistance, anti-snapping, and general toughness.

The biggest threat to steel frames is rust, and once you protect the frames with an anti-rust spray, you can prevent rust and use the bike frame for years.

3. All-Terrain Dominance

Mongoose Argus’s dominance off-road and on-road is undisputed. These fat tire MTBs come with massive and knobbier tires that roll over everything on their path.

Whether you want to ride over snow, thick mud, gravel, or soft sand, Mongoose Argus will do the job. You can even ride on paved roads even though you’ll go slower because of the rolling resistance that the knobby tires will suffer.

4. Reliable Brakes

All-terrain tires are nothing without the most responsive disc brakes, and that’s why Mongoose opts for mechanical and hydraulic disc brakes for this bike line.

The disc brakes are powerful to offer adequate stopping force even when going over slippery surfaces like snow and mud. In general, the brakes massively boost the bikes’ safety.

5. Ease of Riding and Comfort

These bikes come with fat tires, which means they are easy and comfortable to ride on challenging surfaces. They enjoy more traction and stability, and as a result, the control is almost seamless.

The fat tires also absorb shock to make up for the absence of suspension.

6. Smooth Gearing

These bikes usually have a 1-11 speed gearing system other than the kids’ Argus MX. Thus, shifting is smoother across various terrains that you tackle.

Overall, the geared drivetrains allow you to go mountain biking in the snow or dirt racing on the beachside.

7. Low Maintenance

These bikes may be geared, but their drivetrains are essentially simpler. They don’t have many components, making their maintenance easy. In most cases, you need to clean and oil the fat bike, and that’s it.

8. Style Variety

Generally, Mongoose Argus comes in about six styles that are as follows:

  • MX – MX is a BMX-style fat bike best for adventurous kids
  • Sport – Argus Sport is the speediest and most athletic Argus fat bike
  • Trail – Argus Trail is the best choice for trail riding
  • Argus ST – Argus ST is the step-thru version of the Argus Trail, best for casual riding
  • Comp – Argus Comp is the dedicated competition fat bike line
  • Expert – Argus Expert is best for advanced fat bikers
