Buying Guide


Mountain bike categories

There are many types of different mountain bikes, each offering a different style of ride. If you’re new to mountain bikes, you’re probably asking your self; Which type is good for me?

To help you answer this question, we gathered and classified all mountain bike types into two main categories; hardtail bikes and full suspension bikes.

  • Hardtail bikes:

A hardtail means that a bike doesn’t have back suspensions. Riders either love or hate them, but one thing is sure though; they’re durable, light, and affordable.

Also, riding hardtail bikes on rocky trails is challenging since they don’t have back suspensions to absorb impacts. Generally, riding hardtail bikes is a great way to learn mountain biking; Riders have to avoid rough lines, forced to anticipate the smoother line for their butt, they learn to plan runs and get better reflexes.

  • Full suspension bikes:

A full suspension bike has both front and back suspensions. Most beginners and advanced riders are riding full suspension bikes because they provide more comfort and speed, especially for downhill.

The extra weight brought by the additional suspension and the modified frame are the trade-offs for a smooth, fast and nimble ride.

Also, since rear suspensions absorb force, full suspension bikes are usually harder than hardtail bikes for climbing up hills.

Types of hardtail bikes

  • Cross-country:

Cross-country bikes are ideal for long fast pace runs on flat trails; whether you want to go uphill or to reach high speeds, cross-country bikes offer perfect features to enjoy your rides in the forest.

These bikes offer low travel and often come with large wheels (usually 29-inches). While the low ride carries speed, the large wheels help the rider clear significant obstacles.

  • Fat bikes:

These bikes are great for beginners; the large front and back tires offer tremendous traction and provide a sense of security to new mountain bike riders. In fact, the 3.7 inches to 5+ inches tires forgive on rough rocky lines.

Types of full suspension bikes

  • Trail bikes:

Trail bikes offer more versatility than cross-country bikes. In fact, you can ride uphill, downhill, and on a multitude of different terrains. With significant suspensions, trail bikes adapt to flat trails as well as rocky downhill trails. If you’re not sure how you’ll use your mountain bike, go for a trail bike.

  • Downhill bikes:

Downhill bikes aren’t for casual rides in the forest; their purpose is speed, jumps, gaps, and wooden ladders. Downhill bikes are not made to climb up the mountain, but to go down as fast as possible. In fact, downhill riders don’t bother cycling back up; they usually take a lift to the top of the mountain.

These bikes are usually characterized by enormous front suspensions to absorb the heavy landings. Indeed, downhill bikes are for advanced riders with rough downhill experience.

  • Enduro bikes:

Enduro bikes offer a style of riding that’s in between downhill and trail. They’re for aggressive riders that are more focused on technical downhill runs than annoying uphills.

Size

Mountain bike manufacturer usually expresses sizes according to the seat tube’s length. Most brands have 3 different sizes; S, M, and L. Some manufacturers add XS and XL sizes.

To help you find which bike size you have, see our size chart below:

  • XS is bike size between 13 to 14 inches: For riders between 5 and 5 feet 4 inches
  • S – 14 to 16in: 5ft 4in and 5ft 7in
  • M – 16 to 18in: 5ft 7in and 5ft 10in
  • L – 18 to 20in: 5ft 10in and 6fr 1in
  • XL – 20 to 22in: For riders over 6fr 1in

Frame materials

The bike’s frame has an important impact on the weight, quality, and durability of your mountain bike.

Most entry-level bikes have aluminum alloy frames. These bike’s weight and performance depend on the manufacturing quality and the selection of aluminum.

More expensive bikes come with frames containing steel, titanium or even carbon fiber. Titanium and carbon fiber frames typically come with premium quality mountain bikes.

Wheels sizes

There are 3 main wheel sizes available:

  • 26-inches wheels

A few years ago, riders didn’t have the choice between different wheel sizes; all mountain bikes came with 26-inches wheels. Nowadays, most mountain bikes come with 27.5 or even 29-inches wheels.

26-inches wheels are easy to maneuver and require small efforts from the rider.

  • 27.5-inches wheels

Bikes with 27.5-inches wheels are a good standard. In fact, they offer more performance than the 26-inches on rough terrain and are easier to maneuver than the 29-inches.

  • 29 inches wheels

While 29-inches wheels require more effort during accelerations, their size allows keeping high speeds during long runs. Also, they offer a wider attack angle for aggressive riders.

29-inches wheels are featured both on hardtail bikes and full suspension bikes.

Tires

The essential thing to understand about tires is that thin tires have a small contact area with the ground; With less friction, thin tires spin faster than wide tires.

Also, because the contact patch is small, they’re bumpier on rough terrain and won’t clear small obstacle as easily as wide tires. However, thin tires are nimbly providing fast reactions on technical runs.

On the other hand, wide tires require a lot of effort during accelerations. Also, they provide extra friction with the ground; riders need to put more effort to reach high speeds. However, they make rough and rocky terrain feel smooth and provide extra rebound to your overall setup.

Brakes

  • Rim brakes

Best mountain bike under 300 rim brakes

Most entry-level mountain bikes feature rim brakes. Rim brakes are to pads located directly on both sides of the wheel rim. When the rider exerts a pressure on the brakes, the 2 pads compress the rim to slow down the bike.

  • Disc brakes

Best mountain bike under 300 disc brakes

As their name suggests, disc brakes don’t directly slow down the wheel; Instead, they exert pressure on the disc brakes. The disc brakes spin together with the wheels; when they slow down, the wheels slow down.

Disc brakes offer consistent and robust braking in all weather conditions. Also, they require less finger pressure from riders preventing unnecessary hand tensions.

Maintenance

Now that you’re aware of the different mountain bike types and parts, you have to know how to keep care of your bike.

Nothing complicated, you should have a pump, few spare tubes, and patches for eventual punctures. Also, having a small set of tools and products will help you fix some problems now and then, such as lubricate your chain or tighten specific bolts.
