What Trail Type You Will Be Using

The best thing to do first is figuring out what kind of riding you will be doing most often, and then choose your mountain bike based on those requirements.

XC or Cross Country mountain bikes are best for day-long rides and racing using mildly challenging trails and path. XC mountain bikes are generally lighter because they are often used for speed.

Enduro/all-mountain bikes are great for climbing and also excellent for downhill for conquering challenging mountainous terrains.

Downhill mountain bikes are best for speed and gravity (think big jumps!).

Trail mountain bikes are the best mountain bikes for climbs and descents. These usually have front and rear suspensions for exploring all types of trails without worrying about going too fast or far off the beaten path.


What to Look for When Buying a Mountain Bike Under $700

Frame geometry

Frame geometry should be one of the primary considerations when looking for mountain bikes. Different frame geometry styles are designed to fit other riders and positions on a bike. Your height, weight, leg length, and arm span will all determine what style is best suited to you.

A smaller frame size (15″-16″) will generally be better unless the rider has exceptionally long arms or is heavier than usual because they may bend too much when riding downhill on rough terrain.

Medium frame size (17″ – 19″) works well for people of any size, especially those that fall between small and large sizes. Large frames provide more stability at high speeds but can be difficult to handle off-road.

Frame material

The frame is the one part of the bike that you will constantly be interacting with, and it can dictate a lot about how comfortable your ride will feel. Most mountain bikes for beginners use an aluminum frame. These frames are generally the best for people who want to keep things on the lighter side because they’re durable and lightweight. 

Steel frame bikes are much heavier, but they also offer a comfortable ride and will last for years to come. 

Titanium frames are the best mountain bikes for riders looking to shave weight, as they’re the lightest material available on the market today – but also one of the most expensive.

Wheel size

The wheel size is also essential in how it looks and because many benefits come with larger wheel sizes. Some of these are greater stability over obstacles like roots or rocks, increased traction so that your tire won’t slip while cornering, and better grip, so they’re less likely to skid if things get wet or loose dirt gets pushed onto them during braking.

27.5 inches and 29 inches are the three main wheel sizes used on mountain bikes. Generally, bigger wheel size is better for riders looking to ride over rough terrain because they provide more grip and stability. Smaller wheel size, on the other hand, is faster but less stable and responsive in tight turns.

Suspension Type (Hardtail vs. Full Suspension)

A suspension system has two main components: a suspension fork, which connects the front wheel to the frame and absorbs bumps in the terrain; and rear shock absorbers, which dampen vibrations from the rear wheel. Hardtail bikes have only a front suspension fork; full-suspension bikes have both front and rear suspension systems.

Rigid bikes, which have no suspension system at all, are a great option for cross-country riding on smooth terrain. But if you’re tackling more technical terrain, or if you’re a beginner rider, it’s worth investing with at least some suspension system in your first mountain bike.

Most beginners may want a hardtail as their first mountain bike, which provides more pedaling efficiency and is best for riders with little experience in off-road riding. These mountain bikes also tend to be less expensive than full-suspension models, making them the best mountain bikes if you’re on a budget or just starting. Dual suspension is best for riders who want to ride over rough mountain terrain in total comfort.

Brakes (Rim vs. Disc)

Brakes are categorized as either rim brakes or disc. Rim brakes are less expensive and work well on dry terrain, but can suffer in wet conditions. Disc brakes offer more consistent performance regardless of the weather, so if you anticipate doing a lot of mountain biking in rainy or wet climates, it’s worth investing in a bike with good-quality disc brakes.

Disc brakes have two types of pads: mechanical and hydraulic. Mechanical brakes are controlled by a cable, and hydraulic disc brakes use fluid to transmit force from the brake lever. Hydraulic brakes are more powerful and offer better modulation than mechanical brakes, but they require more maintenance as the brake pads need to be replaced more often.

Derailleurs

The derailleur (front and rear derailleurs) system is responsible for shifting gears on your bike. You want to look for a drivetrain system that provides smooth and precise shifting, as well as good durability. Shimano and Sram are two popular brands of derailleurs, each with its own advantages.

Shimano offers more budget-friendly options, while SRAM is more expensive but offers better performance. Either one will be a good option if you’re looking for smooth and reliable gear shifting.

The front derailleur is responsible for shifting the chain between the two or three front sprockets, while the rear derailleur shifts between the larger number of gears at the rear. You should choose the number of gears you need based on the terrain you’ll be riding and how many hills or flat sections you are likely to encounter.

Tires

Tires play a big role in the performance of your mountain bike. A good set of tires will have the right balance of grip, speed and durability for the terrain you’re riding on. Most tires have widths ranging from 2.3–2.5 inches, with more aggressive tires going up to 3 inches in width. Fat tires provide more grip for tackling technical terrain, while narrower tires are better for faster and smoother trails.


Frequently Asked Questions

How much should I spend on my first mountain bike?

You should spend between $500 and $700 on your first mountain bike, which will be best for entry level bikes.

Do 29ers climb better?

Yes, 29ers climb better than 26ers or 27ers. With a 29er, it is easier to roll over obstacles like rocks.


Conclusion

There is no single mountain bike that will work for everyone. It will always depend on a rider’s preference, terrain, and budget. That said, if you are looking for a quality and affordable MTB, you might want to try the Mongoose Impasse. It is a tried and tested MTB that can hold its own among higher-end brands.

Have a fun ride!
