How We Came Up with Our Top Choices in This Category
We carefully selected bikes that were sturdy, lightweight and provided value for the money. Most of these bikes can be customized if you decide to stick with the hobby so don’t worry about not getting a good bike.
We also limited the bikes we reviewed to those in the mens or adult, standard mountain bike category.
We figured that it would be hard to compare different types of mountain bikes with standard trail mountain bikes or cross country bikes.
Electric bikes, women’s bikes, and fat tire mountain bikes are used for widely different purposes.
We reviewed bikes that had good quality components (which to be honest are hard to find in this price range). The good news is that you can find good mountain bikes at reasonable prices with just a little bit of legwork and research (which we did for you).
Several of these bikes are best for trail riding, while others are simply great for everyday use.

- 27.5” tires
- Lightweight aluminum frame

Being that this bike was designed for gravel, it would make transitions from gravel to moderate trails or even wooden bridges a cinch. Consider this bike if you head out to campgrounds a lot because this would be perfect to get around the site.
The interesting thing about this bike is that the marketing materials refer to it as lightweight but it’s clearly not one of the lightest bikes we reviewed when it weighs over 36 lbs.

Mongoose Switchback – Best Brand
- Disc brakes
- 27.5 inch wheels
- Tectonic T1 aluminum frame for lightweight durability
- Internal cable routing
|Easy to assemble
|Bike is on the heavier side
|Looks great in person
|Many have said that the components are not well made and may get damaged
|Stylish mountain bike
|Some users reported the seat being uncomfortable
The Switchback from Mongoose is a very highly rated bike but in our opinion it really depends on what you intend to use it for. This is probably at best a bike that you cruise around the neighborhood in and maybe use around town.
It’s just not built for true mountain biking or off road adventures so that should be considered when assessing whether or not this will be a good bike for your needs.
Many riders have mentioned that this bike will handle great after a little tuning and adjustment. But be careful when riding this bike on hard trails as the constant jarring may dislodge parts or damage them when they get knocked around.
Schwinn Mesa 1 – Best 27.5” Bike
- 27.5 inch wheels
- Aluminum frame with Suntour XCT30 D suspension fork
- Shimano BR-MT200 hydraulic disc brakes
|Large frame that can accommodate riders from 5’10 to 6’1
|Some user experienced issues with derailleurs
|Hydraulic disc brakes
|Plastic pedals have issues as some stripping can occur
The Schwinn Mesa 1 is the trail bike for riders who want to explore beyond the dirt paths and gravel trails at an affordable price.
The Shimano hydraulic disc brakes provide the best stopping power of all the bikes we’ve reviewed. The hydraulic disc brakes are more efficient than mechanical disc brakes as you need to provide less pressure at the lever to stop the bike. These are very hard to find on bikes in this price range.
What to Look for When Buying a Mountain Bike Under $700
Use this guide to understand what to look for when buying your mountain bike.
Types of Mountain Bikes
The type of trails or terrain you want to ride largely determines what kind of bike that you should consider. For this guide, here are the main types of mountain bikes that will be discussed in detail: Cross Country, Trail, Downhill, and All-Mountain/Enduro.
The pedals are the engine of a cross country bike and manufacturers spend a lot of time on this component. As a result, these bikes are efficient & fast. These high-performance bikes are generally lighter in weight due to the lack of cushioning.
Trail Mountain Bikes
Trail biking is another variant of the mountain bike. The bikes are versatile and can be used for anything from fast descents to steep climbs. If you want to ride every trail on any terrain, you should consider getting a trail mountain bike.
Downhill Mountain Bikes
Downhill mountain bikes are great for riding downhill but not so much when you’re riding uphill, on flat terrain, or riding long distances.
Enduro or All-Mountain
Enduro bikes are generally great for mountainous terrain as they’re designed for going down hills. They’re long and heavy, but for good reason.
The suspension is top notch and the geometry is designed to be stable, so it’s a great bike for downhill use. However, it should be stated that the suspension is a huge benefit when going downhill.
Frame geometry is one of the most important factors to consider when looking for the perfect mountain bike. Different frames are designed for different bodies that may differ in height, weight, leg length, arm length or span.
Shorter bike frames are usually great for most riders unless they have extremely long arms or weigh more than your average bear. This is because the extra weight and stress can cause the frame to bend when riding downhill on rougher terrain.
For most riders, the best bike frame will fall between 16 in and 18 in which is considered medium.
The large bike frames provide more stability and durability but can be hard to handle when biking off-road. These frames tend to range from 18 inches to 20 inches.
The frame is one of the parts you’ll be constantly in contact with when you ride your bike, so it’s really important in the whole mountain biking experience. It’s literally the foundation of your entire bike.
Aluminum frames might be best for someone who wants to keep their bike light weight but aren’t as concerned about the durability of the frame because they don’t plan on abusing it on rugged terrain.
It’s important to note that aluminum doesn’t dampen vibration as much as other materials which can make a bumpy ride more noticeable.
Steel frame bikes are much heavier, but they also offer a comfortable ride and will last for years to come.
The good thing about steel bike frames is that not only do they feel very comfortable, but they can last for years and years. They will also be heavier, but this offers a certain level of stability on bumpy roads that some cyclists prefer.
Titanium frames are perfect for riders who are looking for a frame and material that is both light and durable. Another benefit is that these frames won’t become brittle over time as they age.
Carbon Fiber Frame
Carbon fiber is another high-end frame material that is common on the high performance mountain bikes. While it is the most expensive material it doesn’t sacrifice any of the benefits of the other frame materials.
When it comes to mountain bikes, wheel size matters. The size of the wheel affects how fast and how far you can go on a bike. The larger the wheel, the more difficult it is to maneuver. Small wheels allow you to ride faster and further without much effort.
There are three sizes that you’ll come across when choosing a bike. The 26-inch wheel is the most common and best for everyday use because it’s lightweight and easy to maneuver.
The 27.5-inch wheel is best suited for technical riding and for riders that are shorter or average height.
29-inch wheels are usually preferred for fast trails and for riding over rugged terrain with ease. These wheels are also designed for tall riders.
There are several types of suspension that one should be aware of when shopping.
Riders who are new to mountain biking may want to start with entry-level hardtail mountain bikes, which are more efficient for pedal power and are the best introduction into off-road riding. For those looking to save their money or are just starting out, hardtail suspension is the best option as they are often less expensive than full-suspension bikes.
Rigid forks are a type of bicycle fork that does not have any suspension to cushion the ride. They can be found on mountain, hybrid and road bikes. Rigid forks do not have shocks or springs that will help keep the front wheel in contact with the ground and make it easier to absorb bumps in the terrain. This makes for a rough ride on bumpy terrain.
Riding on rough terrain can be uncomfortable with standard suspension forks. Dual suspension forks are the perfect solution. These forks offer the best of both worlds giving riders the ability to enjoy long rides without worrying about jarring or uncomfortable rides.
