Buying Guide: Mountain Bike

  • Riding style and terrain
  • The frame
  • Suspensions and shock absorbers
  • Wheel dimensions
  • Braking system
  • The transmission
  • Men’s or Women’s bikes

Riding style and terrain

The first criterion looks at your type of driving as well as the type of terrain on which you want to go. If you are looking for a versatile bike that can tackle most terrain or need a bike that specializes in a certain type of trail, we recommend a trail bike, as the majority of riders are very satisfied with it.

Budget-conscious cyclists will look for more affordable hardtail bikes instead.

The frame

The aluminum or carbon frame is the first choice you should make. Choosing an aluminum frame offers great cost savings, although it is slightly heavier and tends to bend more easily than a carbon frame. However, if you are looking to exercise in an amateur way, aluminum is the perfect option!

Consider carbon frames if investing in your bike is your priority and if you want to keep it for a very long period of time or for conscientious training such as that of real sportsmen. Carbon fiber ages better than aluminum, which is still an important point to consider.

Suspensions and shock absorbers

The most important criterion for the majority of bikers still remains the choice of the bike according to the suspensions it offers: whether they are complete or more rigid by only being at the front.

Some bikes have a so-called “suspension lockout” feature that allows you to voluntarily turn off the suspensions when you are riding. This can come in handy for anyone who wants to drive in the mountains or up steeper climbs, where the suspensions could absorb too much of the energy.

Wheel dimensions

The wheels of mountain bikes have different heights and obviously you have to choose the one that best suits your needs. Some models are a standard for children and others for adults.

The wheels should be of good quality, but pay attention to their rim width, as this can make the tires more or less efficient.

Braking system

Typically, the brake system of mountain bikes focuses on disc brakes. Mechanical disc brakes are still the cheapest option when buying your bike, but they are less efficient than their hydraulic or brake fluid counterparts. It is therefore a very important choice.

The transmission

As for the transmission, you will need to inquire about the number of chainrings. If your bike has a dual-chainring drivetrain, that means you’ll have controls on both sides of the handlebars, which is a real plus! It’s simpler, easier to manage and leaves more room for seat post drip control, not to mention the higher sturdiness.

Women’s bikes

Women-specific bikes have bars and cranks on the saddle. Also, they usually have lighter shocks than unisex bikes.

The bulk of mountain bikes are considered unisex bikes, so every bike is suitable for women as well, in theory. The only problem that arises is that the unisex models are designed for average riders.

Generally speaking, men are taller and heavier than women, which makes the design of these types of models unfair.

Many bicycle manufacturers counter this problem by designing female models, and others specialize squarely in designing unique bicycles for women, suitable for their size and weight.

Apart from the aesthetic aspect of the frame, the frame and the shock absorbers are the essential elements that distinguish a women’s trekking bike from a men’s trekking bike. First of all, a bicycle must be adjustable. Secondly, the fork and shock absorber must respond to small impacts and fully absorb the more brutal impacts of rough terrain.

In conclusion

Don’t spend the entire budget on the bike alone, since several other tools are needed for mountain tours, such as a sports suit, protective gloves, but above all a suitable protective helmet. Always consider the additional expenses, unless you already have the remaining equipment.

Buying a Mountain Bike is more difficult than taking a hybrid bikes. We hope this article helped you understand which bike is best suited to your needs.
