Trail Bikes

Trail bikes, also known as trail mountain bikes, are the jack-of-all-trades in the mountain biking world. They are recognized for their versatility, catering to various terrains and riders of different skill levels. With shocks on the shorter end of the travel spectrum, ranging from 120 to 150mm, trail bikes allow for efficient pedaling, which is advantageous on a variety of trail types. This makes them a popular choice for riders who love to explore a broad spectrum of mountain biking endeavors.

Therefore, if you’re seeking a bike capable of handling varying terrains and matching your adventurous spirit, a trail bike could be your ideal choice.

All-Mountain Bikes

For those who love to ride trails tackle challenging trails featuring steep climbs and descents, all-mountain bikes reign supreme. These bikes are designed to conquer the mountains, with the following features:

  • Full-suspension systems providing enhanced stability and control over technical terrain and during downhill sections

  • Suspension travel of 140–170mm

  • Head-tube angle between 65–68°, striking a balance between uphill efficiency and downhill control

If you thrive on challenges and the thrill of descents, then an all-mountain bike is the perfect companion for you.

Cross-Country Bikes

Cross-country mountain bikes are the marathon runners of the mountain biking world. They are tailored for efficient climbing and pedaling, featuring lightweight frames and components. With 60–120mm of suspension travel and geometry similar to road bikes, they are designed to cover ground quickly and efficiently. However, they shine the brightest on smooth trails, excelling on surfaces with fewer technical challenges.

If speed, efficiency, and the thrill of racing define your style, a cross-country bike could be your ideal riding partner.

Enduro Bikes

Enduro mountain bikes are the rockstars of the mountain biking world, built for the thrill of steep and rough terrains. They come equipped with a hefty suspension travel range between 130 and 180mm to ensure optimal descending and handling of significant trail features. Their geometry features a head-tube angle that’s slacker than trail bikes but a steeper head tube angle than downhill bikes, typically between 63 and 66 degrees, aiding in stability during descents.

If speed and challenging terrains excite you, an enduro bike could be your passport to an adrenaline-charged ride.

Downhill Bikes

Downhill full suspension mountain bikes are the daredevils of the mountain biking world. Constructed with heavy suspension components, they offer over 200mm of travel and feature a long wheelbase and slack head tube angle between 62-65 degrees, providing stability at high speeds. These bikes are designed to conquer steep, rough terrains and excel on downhill biking courses filled with drops, jumps, gaps, rocks, slips, and slides.

If you’re a thrill-seeker who thrives on high speeds and challenging descents, a downhill bike could suit you perfectly.

Fat-Tire Bikes

Fat-tire bikes are the off-roaders of the mountain biking world. These bikes have wide tires, typically 3.8 inches or larger, which provide improved stability and floatation on surfaces where traditional mountain bike tires would sink. They are especially suited for riding on soft, unstable terrain such as snowy paths and sandy beaches.

However, their heavy and wide tires can make them less nimble and slower on traditional dirt trails compared to standard mountain bikes. If venturing off the beaten path and conquering challenging terrains is your style, a fat-tire bike could be your adventurous ally.

Electric Mountain Bikes (e-MTB)

Electric mountain bikes, or e-MTBs, are the future of the mountain biking world. These bikes are equipped with battery-powered motors and pedal assist, enabling riders to cover more ground with less effort. They offer the capability to accommodate different trail rules and allow riders to do more exploration and climbing with the support of pedal assist.

If you aspire to elevate your mountain biking experience or need a little extra push on your rides, a new mountain bike, specifically an e-MTB, could be the ideal choice for you.

Hardtail or Full-Suspension?

Having explored the different types of mountain bikes, it’s time to discuss the details – the suspension system. In the world of mountain bikes, you essentially have two choices – hardtail or full-suspension.

Hardtail mountain bikes feature:

  • a fixed rear triangle without rear suspension

  • making them well-suited for less challenging trails

  • often preferred by cross country riders for their pedaling efficiency and lightweight design.

On the other hand, full-suspension bikes include a rear shock that allows for vertical wheel movement to absorb impacts, offering a smoother ride on rough terrain. Choosing between the two boils down to several factors – your budget, riding style, and the terrain you plan to navigate.

If you’re on a budget, hardtail or rigid mountain bikes are recommended as full-suspension bikes at this price point are typically too heavy and not reliable for off-road use. But if you’re planning to tackle more challenging terrains and want a smoother ride, a full-suspension bike may be worth the investment.

Wheel Size Matters

29er vs 27.5

Just like Cinderella’s glass slipper, when it comes to mountain biking, the size does matter! Mountain bike wheels come in 26, 27.5, and 29-inch diameters, each offering a different riding experience. The 29-inch wheels, or 29ers, offer more traction and a greater ability to roll over obstacles, providing a smoother and more stable ride. They’re especially suited for cross-country and trail riding.

On the other hand, 27.5-inch wheels offer better maneuverability and accelerate more quickly than larger wheels, making them ideal for tight and twisty trails. Keep your riding style and the terrain you’ll be navigating in mind when selecting your wheel size.

Frame Material Choices

The frame is the backbone of your mountain bike, and the material it’s made from plays a crucial role in your bike’s weight, strength, longevity, and price. The most common materials are:

  • Aluminum: offers a balance of low weight, stiffness, and affordability, making them common in budget to mid-range mountain bikes.

  • Carbon fiber: provides the best stiffness-to-weight ratio and is moldable into various shapes, but tends to be more expensive.

  • Steel alloys and titanium: less common due to their weight and cost respectively.

When selecting your mountain bike, take into account the frame material that aligns best with your needs and budget.

Key Mountain Bike Features

Let’s examine the core elements – the key features that constitute a mountain bike. There’s a lot to consider, including:

  • Suspension travel

  • Gearing options

  • Brake types

  • Tire options

At its core, a suspension mountain bike is designed to absorb impact, with a travel range that can vary from 80 mm for smoother riding purposes to up to 200 mm for aggressive downhill experiences.

The drivetrain and suspension quality also significantly influence the mountain bike’s performance. But let’s break it down and explore each of these features in detail.

Gearing Options

Gearing is like the DNA of your mountain bike – it determines how your bike behaves under different conditions. Mountain bikes come with triple, double, or single chainring setups. Single chainring systems, also known as 1x drivetrains, are favored for their lighter weight and simpler design.

Bikes with two or three chainrings provide a larger range of gearing options, which includes very low gears to facilitate climbing. Your riding style, terrain, and fitness levels may dictate your preference for one setup over another.

Suspension: Air vs. Coil

Suspension systems are the heart of suspension mountain bikes, designed to absorb impact, improve traction, and increase comfort for the rider. Mountain bike suspension systems utilize air, coil, or both types of springs to facilitate these benefits. Air forks rely on pressurized air along with suspension fluid for resistance, whereas coil forks use a metal coil spring.

Air suspension systems offer better impact absorption and can help reduce rider fatigue compared to coil spring systems. Your preference between the two might depend on the type of terrain you’re navigating and your personal taste.

Brake Types: Hydraulic vs. Cable-Actuated

Brakes are the lifeline of your mountain bike. After all, what good is speed without control? Mountain bikes utilize either hydraulic disc brakes or cable-actuated disc brakes as their main braking systems. Hydraulic disc brakes provide better performance and responsiveness when compared to cable-actuated brakes. However, they typically come at a higher cost and may require more specialized maintenance than cable-actuated brakes.

Your preference for a braking system may hinge on your budget and maintenance skills.

Tubeless Tires

Tires are the feet of your mountain bike, and just like you wouldn’t wear flip-flops for a hike, choosing the right tires is crucial for your biking adventure. Tubeless tires provide better traction and a smoother ride, and reduce the chance of pinch flats. However, they require special setup and maintenance, and not all bikes come with ‘tubeless-ready’ rims.

If you’re pondering the switch to tubeless, ensure that your wheels are tubeless-ready and be ready for some additional setup and maintenance work.

Finding the Right Fit

Just as a well-tailored suit enhances your appearance, a well-fitted bike enhances your riding experience. Selecting the correct frame size, connected to one’s height and the stack and reach measurements of the bike, is integral to a rider’s comfort, overall enjoyment, and performance.

Key bike fit measurements such as effective top tube length relate to the rider’s arm length and riding posture, while standover height ensures comfort and safe dismounts. Before you set off on your mountain biking adventure, ensure your bike is the right fit for you.

Essential Accessories and Maintenance

Now that we’ve covered the basics of the mountain bike, let’s talk about the cherry on the cake – the accessories. Key mountain biking accessories include:

  • A GPS unit for route tracking

  • Protective kneepads for safety on technical trails

  • Comfortable grips to reduce fatigue

  • A well-stocked repair kit

These accessories can enhance your biking experiences at your local bike shop.

But it’s not just about accessorizing, regular maintenance is critical before embarking on a ride. Professional fine-tuning services should be considered when the mountain bike does not react as expected, ensuring both rider safety and bike longevity.

Summary: How to choose a mountain bike.
