How Do You Choose the Best Mountain Bike?

Bike Style

Downhill mountain bikes are a great option if you’re an experienced rider and have an obsession with speed. They’re extremely durable, with wider tires and frames.

That also means they can take on really rough terrain at high speeds. While they do absorb a lot of shock and vibration from the trail, they can also be tougher to get up steep hills.

Cross country mountain bikes are nice and lightweight. That means you can gain a fair amount of speed for fairly little effort.

You may see them referred to as XC bikes, but they’re still the same. There are race and trail cross country bikes, but they both excel in agility and speed.

Freeride mountain bikes are like the hybrid of cross country and downhill bikes, but they’re lighter and easier to maneuver around. Still, they’re not great to get uphill, but easier than downhill bikes.

The frame is pretty flexible and compact, which allows for any number of stunts you might want to try out. 

Dirt jump bikes are more like bmx mountain bikes that you can take to the trail, or to the streets.

With larger handlebars, front suspension, and a single speed setup, they’re great for doing tricks. If you’re a real daredevil, it’s probably your bike of choice. 

All mountain bikes are true to their name. They’re a great choice for people that like regular trail riding, but may also want to brush up their trick swag. They have sturdy, durable frames and typically come with full suspension too.

Suspension Type

When it comes to mountain bike suspension, you have a few options: full, rigid, or hardtail. 

Full suspension does what it sounds like, and it absorbs shock on both ends. That means you don’t just rely on the rear shocks. The front fork does its fair share of eating up rebound from all those rugged areas on the trail.

Since it’s well balanced in suspension, you can climb fairly well, without noticing too much impact from the trail. 

Rigid suspension mountain bikes are definitely less common. Essentially, they don’t have any suspension to speak of. They’re much more affordable but without the comfort of suspension.

Because of this, most have wider frames and tires to compensate somewhat, and it does help to absorb shock from the trail. Rigid mountain bikes have lower tire pressure which reduces the impact you’ll actually feel. 

Hardtail bikes are easier to maintain than full suspension bikes, but they absorb more shock than rigid bikes do. They’re also typically more affordable than full suspension bikes, because they don’t have rear shocks.

It’s a common design for cross country mountain bikes, and all mountain bikes. That said, you’ll rarely see this on a downhill bike, since the front fork does the job of absorbing nearly all of the impact of the trail.

Wheel Size

First, for kids’ mountain bikes, you’ll usually see wheels that are about 24 inches. This can vary, but it’s not often larger than 24 inches. If kids are really young, they might use 20 inch wheels.

29 inch wheels are great for long rides. You can cover a lot of trail territory on these and they’re a favorite for cross country mountain bikes. The only downside is it can take a little but to get going and get your momentum up.

The good news is that once you have your momentum, they keep it going and easily roll over obstacles. 

26 inch wheels used to be the standard. However, it’s not as common anymore, and 27.5 inch wheels are seen as a reliable, more common option.

These are used for pretty much any type of riding, since you get the best features of each wheel size. Whether you prefer hardtail or full suspension, they’re easy to maneuver and get over tough terrain.

Frame Materials

Steel is a popular frame material, and it’s certainly affordable and durable enough for even the toughest terrain. The only downside is that, for mountain trail riding, it’s somewhat heavy. 

Carbon fiber is another frame material choice, and it’s nearly feather weight compared to steel.

Cross country riders love it because of that; it’s much easier to take a lightweight frame anywhere, and it’s quite strong too. However, it is more expensive than other frame materials. 

Aluminum alloy is certainly one of the top choices in mountain bike frame materials. It’s durable, just like you need in a good mountain bike frame.

While it is strong, it’s also significantly lighter than other frame materials like steel, although not quite as lightweight as carbon fiber. It’s a good medium, and it’s much more affordable than many materials.
