Taking these factors into account will help you make an informed decision and ensure a smooth and enjoyable riding experience.

Wheel and Tire Upgrades

When it comes to upgrading your mountain bike, one of the most impactful changes you can make is to your wheels and tires. The standard wheel size for most mountain bikes is 27.5 inches, also known as 650b. These wheels strike a balance between the agility of 26-inch wheels and the rollover ability of 29-inch wheels.

Upgrading to 27.5-inch wheels can significantly improve your MTB experience. These wheels offer better traction and control on rough terrain, allowing you to tackle technical trails with greater confidence. They also provide a smoother ride, absorbing bumps and vibrations for enhanced comfort.

In addition to the wheel size, you can also upgrade your tires to further enhance your mountain biking performance. There are various tire options available, depending on your riding style and the terrain you frequent. For example, if you ride predominantly on loose or muddy trails, you might opt for wider, knobby tires with aggressive tread patterns for increased grip.

Furthermore, consider the tire width when upgrading. A wider tire provides better traction and stability, particularly when cornering or descending steep slopes. However, be mindful of the added weight and increased rolling resistance that wider tires can bring.

When choosing wheel and tire upgrades, it’s essential to consider compatibility with your MTB frame. Ensure that the width between the fork and rear stays can accommodate the wider wheel and tire size. Additionally, check for proper clearance between the tire and frame to prevent rubbing or interference.

Overall, upgrading your wheels and tires can significantly improve your mountain biking performance. Whether you ride for fun, fitness, or competition, investing in 27.5-inch wheels and choosing the right tires can enhance your ride experience and help you conquer any trail with ease.

1. Rinse off the dirt: Before you start cleaning, use a hose or a bucket of water to rinse off the mud, dirt, and grime from your bike. Make sure to direct the water away from any sensitive areas, such as the bearings or the suspension system.

2. Use a gentle cleaning solution: Mix a mild soap solution or a dedicated bike cleaner with water in a bucket. Avoid using harsh chemicals or solvents that can damage the paint or the components of your bike. Apply the solution onto a soft sponge or brush and gently scrub the frame, wheels, and other parts.

3. Clean the drivetrain: The drivetrain, including the chain, cassette, and chainrings, can accumulate a lot of dirt and grease.

Off-Road Riding Tips

When it comes to off-road riding on a 27.5-inch mountain bike (also known as a 650b), there are a few tips to keep in mind to ensure a smooth and enjoyable ride. Whether you’re a beginner or an experienced rider, these tips will help you navigate the trails with ease.

1. Choose the right tire pressure

Having the correct tire pressure is crucial for off-road riding. With a 27.5-inch mountain bike, it’s recommended to inflate the tires to a pressure that suits the terrain you’ll be riding on. Lower tire pressure provides better traction and control on loose or rough surfaces, while higher tire pressure is better for smoother or hard-packed trails.

2. Master the art of body position

Proper body position is key to maintaining control and balance on off-road trails. When riding a 27.5-inch mountain bike, make sure to keep your weight centered and evenly distributed between the front and rear wheels. Bend your elbows and knees slightly to absorb shocks and maintain stability. Keep your eyes on the trail ahead and look where you want to go, rather than focusing on obstacles.

3. Use the right gear

When riding off-road with a 27.5-inch mountain bike, it’s important to choose the right gear for the terrain. On steep climbs, use a lower gear to maintain traction and pedaling efficiency. On descents, shift to a higher gear to keep your speed in check. Practice shifting gears before hitting the trails to ensure smooth transitions.

4. Learn how to brake effectively

Braking is essential for off-road riding, especially when going downhill or navigating tight turns. With a 27.5-inch mountain bike, use both the front and rear brakes simultaneously for maximum stopping power. Avoid locking up the wheels to maintain control. Gradually apply and release the brakes to adjust your speed smoothly.

By following these off-road riding tips, you’ll be well-prepared to tackle any trail with your 27.5-inch mountain bike (also known as a 650b). Remember to always wear appropriate safety gear and ride within your skill level for a safe and enjoyable experience.

Safety and Protective Gear

When it comes to mountain biking with a 27.5-inch MTB, safety should always be a top priority. Wearing the right protective gear can prevent serious injuries and ensure a more enjoyable riding experience. Here are some essential gear items every rider should consider:


A helmet is the most important piece of safety gear for any mountain biker. It protects the head and can prevent serious head injuries in case of a fall or accident. Make sure to choose a helmet that fits properly and has adequate ventilation.

Protective Eyewear

Mountain biking often involves riding at high speeds on rough terrain. Protecting your eyes from dust, debris, and branches is crucial. Consider investing in a pair of durable goggles or sunglasses with impact-resistant lenses.


Gloves provide grip, comfort, and protection for your hands. They can prevent blisters and scrapes, as well as provide better control of the bike. Look for gloves with padded palms and good ventilation.

Elbow and Knee Pads

When riding off-road with a 27.5-inch mountain bike, it’s common to encounter obstacles and potential crashes. Elbow and knee pads can protect these vulnerable areas from cuts, bruises, and more serious injuries. Choose pads that provide a good balance of flexibility and impact resistance.


Proper footwear is essential for mountain biking. Look for cycling shoes that offer a stiff sole for efficient pedaling, as well as good traction for walking on rough terrain. Flat pedal shoes with sticky rubber soles are a popular choice among riders using platform pedals.

Investing in the right safety gear is a small price to pay for the added protection and peace of mind it provides while riding your 27.5-inch MTB on challenging mountain trails.

Budget Considerations

When it comes to purchasing a 650b mountain bike, budget is an important factor to consider. The price range for 27.5-inch MTBs can vary greatly, depending on the brand, components, and overall quality of the bike.

Setting a Budget

Before you start shopping for a 650b mountain bike, it’s important to determine how much you’re willing to spend. This will help narrow down your options and ensure you don’t overspend.

Consider your level of experience and the type of riding you plan to do. If you’re new to mountain biking or just getting started, you may not need the most expensive bike on the market. However, if you’re an experienced rider who plans to tackle challenging trails, investing in a higher-end bike with top-of-the-line components may be worth considering.

Value for Money

While budget is important, it’s also essential to consider the value for money you’re getting with your purchase. Research different brands and models to compare their features and specifications. Look for bikes that offer a good balance between quality components and an affordable price.

Keep in mind that while it’s tempting to go for the cheapest option available, a bike with poor quality components may not last as long or provide the best performance. It’s often worth spending a bit more upfront for a bike that will provide a better riding experience and require fewer repairs or upgrades in the long run.

Additionally, consider the warranty and customer support offered by the manufacturer. A longer warranty and responsive customer service can provide peace of mind and ensure your investment is protected.

Overall, finding the right 27.5-inch MTB within your budget is possible with careful research and consideration. By setting a budget, comparing value for money, and prioritizing quality components, you can find the perfect ride without breaking the bank.
