Giant ATX 3 Bike Review

The Giant ATX 3 bike is a versatile bike that can liven up your ride or exercise routine by riding on parkways, walking routes, and anything in between. It’s comfortable and competent on and off the road, thanks to its flat handlebar, upright positioning, and suspension fork.

ATX has a hardy character and a seamless riding style, and it has the traditional flat-handlebar look of a mountain bike. It has a lightweight but tough ALUXX aluminum frame and a suspension fork with 100mm of smooth travel to absorb bumps.

Its  wheel diameter is not constant but varies depending on the frame size, with smaller frames having 26-inch wheels and larger frames having 27.5-inch wheels.

The massive ATX3 is equipped with a disc brake and a front fork suspension. This is a really entry-level mountain bike, and it’s also a good neighborhood bike that can get you up and down your neighborhood’s hills.

This is also a great bike to have if you want to do some light off-roading. The bike’s fork has a preload adjuster that you can use to make it stiffer or softer depending on your preferences.

Its powerful disc brake is operated by a cable. The Shamano drive train has three rings on the front and seven gears on the back, providing good gear ratios for different types of terrain and speed comfort.

Racks can be added to this bike as well. Rack mounts on the frame allow you to attach a rear rack. There are three color options: black, red, and tan.

Giant has made the switch to 27.5-inch wheels. Many of you are probably familiar with 26-inch wheels. The larger wheel size gives you a faster bike, which is a significant advantage of the 27.5 inch wheels.

The Giant team was able to tweak the geometry around the 27-inch wheels while maintaining a tight rear end. The rims are double walled, allowing the bike to withstand more rough riding (avoid big jumps or backflips)

Aside from the wheels, the tires have very small knobs on them, which is fine for riding on the street and does not provide too much rolling resistance. The tire pressure ranges between 40 and 65 psi.

For off-road activity, I believe 40 psi would suffice to smooth out the road bumps. If you’re riding on the street, you’ll have to experiment with your air pressure to find what works best for you.

The 25.4 alloy handlebar is about the width of an average person’s shoulder. The handlebars cannot be extended (though a wider bar gives you a lot more control if you ride aggressively).

The seat post is fully aluminum. The seat is pretty much basic that is found in most entry-level bikes. The seat is about two hundred and eighty millimeters long and 145 mm wide at the back of it so it’s a decent size without too much padding on it.

Taking Care Of Your Giant ATX 3 Bike

  1. Check that the tires on your Giant Roam bike are properly inflated (a pressure guide can be found on the sidewall of the tyre) and that they are not ripped.
  2. Ensure that your brakes are in good working order. Do not ride your bike if both brake pads do not effectively contact the rim or disc. If necessary, adjust your brakes in accordance with the manufacturer’s instructions.
  3. Check to make sure the wheels are securely fastened and there is no play. Tighten the quick release orthru-axle if necessary.
  4. To prevent rusting, thoroughly clean, degrease, and lubricate your Giant Roam drivetrain. This will reduce pedal noise and keep the pedals from wearing out prematurely. The drivetrain consists of chain rings, cranks, cassettes, derailleurs, and chain.
