Because there are plenty of things you need to consider, I have narrowed down the list for you. Here are the basic and most essential factors you need to look for a mountain bike.
Mountain Bike Gears
One of the best features of mountain bikes is the many gears available to adapt to your adventure. Generally, MTBs can have one gear or up to thirty gears. As you go higher, the speed and strength of your mountain bike change. Inline, most brands require a manual approach for changing the gears of your bike.
In choosing how many gears you need to have for your mountain bike, you need to consider your physique and the terrain where you oftentimes ride. For those bikers who go on many steep and downhill terrains, opting for higher gears is a suitable choice.
In contrast, if you often ride on smooth and flat terrains and you have a strong physique, then going for lower gear levels is ideal.
The skeletal structure of your mountain bike can be made from various materials, of which, steel and aluminum are the two most common compounds. Steel bike frames offer higher durability and resistance against bending, but heavier than the latter. Meanwhile, aluminum bike frames are very light compared to steel, yet still offers substantial strength.
Moreover, some brands of modern mountain bikes already use a combination of metals or an alloy (combined steel and aluminum). With this, you are better to enjoy a semi-lightweight and durable bike frame.
Meanwhile, some MTB frames are also made from carbon fiber and titanium. These materials are much lighter without being fragile.
Categories of Mountain Bikes
This factor can be your first choice before buying your new mountain bike. Each category has its benefits and limitations which you need to understand to learn more about which one best fits your physique and terrain.
- Park Bikes: This type is good for those going for the extreme downhill terrains, where it rolls over bumps and rocky surfaces. Riders must wear a helmet and protective gears to avoid huge cuts and wounds for unexpected events. It has a suspension travel of 170-200+ mm.
- All-Around Mountain Bike: If you want a versatile type, then going for an all-around mountain bike is a wise option. It can efficiently handle steep and downhill terrains. Rocky and bumpy rides will be smooth for this one as well. It has a suspension travel of 140-170 mm.
- Fat Bicycles: I recommend this one for those starting with bikes. Its wider tires are essential for having a convenient and easy trail on smooth and rough road surfaces. It works best for sandy and light snow surfaces. Typically, it has a tire width between 3.7” to 5”+.
- Cross-Country Bicycles: This type is an excellent choice for those who want efficient climbing power and running at a fast speed. It has a suspension travel of 80-100 mm.
- Trail Bicycles: This is the general type of mountain bike that is great for leisure and exciting trail. You can feel a balanced power for climbing and descent with a trail mountain bike. It has a suspension travel of 120-140 mm.
- Full Bike Suspension: With this type, you have both front and rear shock-absorbing mechanism which reduces tension and vibration on the rider. There are exceptional comfort and traction for this suspension style. Bumpy, downhill and steep climbing rides will be hassle-free and convenient when you have this kind of MTB suspension.
- Hardtail Bike Suspension: Taken from its etymology, “hardtail”, it means there is zero suspension on the rear section of your bicycle. The front fork of your MTB only has the suspension feature which protects the rider from approaching head-on bumps and vibrations.
- Bikes with this suspension style are cheaper than those with full-suspension and require lower maintenance as well. Cross-country bicycles commonly have this kind of suspension, where there is a direct power transfer from the pedal towards the rear wheel.
- Rigid: A rigid bike suspension simply entails the absence of the shock-absorbing mechanism both on the front fork and rear section of your bike. MTBs with a rigid suspension comes at an affordable price and lesser maintenance requirements.
Bicycle Brake Mechanism
- Rim Brakes: This braking mechanism can be considered the most common and widely used for all types of MTBs and bicycles. It consists of two brake pads that grip on the wheel rims of the bike.
Pros: It is more affordable to repair or replace compared to disc brakes. Likewise, you can easily see if the brake pads needed to be replaced already.
Cons: Oftentimes, when the brake pads wear out, it goes as well with the wheel rims. Consequently, you need to replace both the wheel rims and the brake pads simultaneously. It provides less braking power on muddy and wet surfaces. You need to press harder on the brake levers located on the grip handle to exert a higher stopping force.
- Disc Brakes: Disc brakes work by gripping on the brake rotor that is attached to the wheel hub. There are two types of disc brakes: hydraulic and cable-operated disc brakes. The former provides reliable and increasing stopping force compared to cable-driven disc brakes.
Pros: It provides superior stopping force on all types of road conditions: wet or dry surfaces. Likewise, there is less strain on the fingers while braking. Moreover, you only have to replace the rotor during your maintenance session.
Cons: In contrast to rim brakes, it is easier to do an ocular inspection if the brake pads need to be replaced already. Replacing broke hydraulic disc brakes are more expensive compared to rim brake replacement.
Size of Bike Wheels
Upon walking into a bike shop, one of the common questions asked by the salesperson will be the wheel size of your bike. Today, there are plenty of wheel sizes available for mountain bikes, which include 26”, 24”, 27.5”, and 29”.
The basic wheel diameter is 26” and is commonly used for medium-sized mountain bikes. Meanwhile, if you want something in between 26” and 29”, then go for a 27.5” wheel size. It offers a balanced trail over smooth and rough terrains.
Rule of thumb, when you opt for longer rides, it is best to choose a larger wheel size because it gives you a longer range of travel. Larger wheel sizes may be challenging to accelerate, but once you are there, it is so easy to keep ongoing.
Frequently Asked Questions
So we are done with the buying guide, pointing out what matters in shopping for your mountain bike. Let me add more information regarding mountain bikes as I provided short answers for these commonly asked questions. Read carefully to gain more insights.
What is the common wheel size for kids?
Choosing a wheel size of 24” for your kid’s mountain bike is a good choice. It is the most accepted option for this age level.
Do I choose a mountain bike with a rigid or hardtail suspension?
Mountain bikes with rigid suspension come at a cheaper price than those with a hardtail. For beginners, you can opt for a rigid suspension to save more while having the standard quality of a mountain bike.
Do I need a mountain bike with many gears?
This depends on your physique and the usual trail you go for. If you often go for downhill and steep climbs, then choosing a mountain bike with several gears would be ideal. In contrast, if your usual trail is flat and smooth surfaces, then going for an MTB with fewer gears would alright.
