Buyer’s Guide



Need a quick primer on how to choose your bike? OK, we got you.

Mountain Biking Today
Not sure what to make of the different bikes you see in our list or in the shops? No problem- in this section, we will inform you of different bike types.

For example, hardtail bikes are mostly used now by cross-country (XC) and beginner riders, and wheels measuring in at 26 inches are mostly a thing of the past.

Handlebars: You will also notice that handlebars are much wider than before and that bikes look much different than they did years ago. Reason being is that the bikes of today handle better in certain terrains, and don’t cost the rider efficiency.

Wheels: And as far as the wheel size goes, rims are just simply bigger on modern mountain bikes. This gives the rider a better time handling the bike.

Frames: Carbon frames are also quite popular nowadays: riders really love this metal because it makes the trail feel smooth as can be, absorbing the input of what’s on the ground. It also offers the rider a strong frame choice that is virtually guaranteed to handle whatever is thrown at it.


Types of Mountain Bikes


What kind of trail will you ride upon? Choose the right bike for the task.


Fat Bikes


Do you love to ride in winter? Does the fact that there is snow on the ground make you excited to ride even though others are staying indoors? If this sounds like you, a fat bike could be what you’re looking for.

You don’t even need to be a winter climate person to appreciate this. These bikes are great for those of you riding in the desert or even along the coastline. You will do well for yourself by purchasing a fat bike which can be ridden no matter the climate or weather. You can ride on snow, dirt, sand or ice with ease.

The big feature about these bikes is that their tire is, well, fat! You will notice these tires are at least 3.6 to 5 inches in width. The more tire you have on the ground, the more traction you will enjoy, and that’s why these bikes are super when it comes to terrains others shy away from such as snow or sand.

Getting one of these bikes will have you pedaling anywhere you want with confidence. These bikes normally feature a rigid fork up to 120 mm and a rear suspension that is minimal or hardtail.


Enduro Bikes


These bikes feature a front suspension of 150 to 170mm and usually a rear suspension of 140-165 mm. Enduro bikes are designed to climb like monkeys and fly like eagles down the hills. These bikes are also very soft on the suspensions, so that, during those rough descents, you have a more comfortable come-down.

They are designed to handle the rigors of enduro racing, but their ability to help you climb and do so efficiently have made them a popular choice with riders that want to hit the high difficulty trails with confidence.


Trail Bikes


Want to confidently go uphill but take the descent like a champ? The trail bike may be just the tonic for what ails you. These bikes feature more in their suspension in the front and the rear. Front suspension travel offers about 120-140mm, and the rear offers 100 to 140 mm of travel.

The shape of these bikes lends themselves to climbing well, but they are quite good when it comes to downhill riding, too. Unsurprisingly, these bikes are the “jack of all trades” of the mountain bike world, they have their riders going out and tackling trails of all difficulties and terrains. Riding conditions hardly matter when you’ve got a good trail bike.


XC Bikes


If you want to be the clear winner when it comes to uphill times, and keep track of your climbs, then it will do you well to take a look at bikes that have lower instances of suspension, larger wheels, and efficiency in pedaling plus a light carry weight. If you plan on riding for many miles, or you have a smooth and relatively easy terrain ahead of you, plan on skipping the rear suspension as a whole and just get yourself a hardtail bike. Depending on how tall you are, a 29 inch wheels are generally the standard when it comes to cross country bikes. If you are a smaller rider, opt for 27.5 inch wheels so you get a comfortable fit and have more control over your ride. It will make corners easy and descending a dream. Cross country bikes are also great for maxing out pedal strokes and going fast while climbing uphill.
