Looking for a new bike? Sometimes the jargon can be a little intimidating. The good news is that you don't have to become fluent in bike speak to decide which bike is best for your two-wheeled adventures. We break down things to consider when choosing a bike.

The bike-buying process can be boiled down to three basic steps:

  1. What type of bike should you get? The right bike for you will depend on where and how you plan to ride. Start by asking yourself where you plan to ride: on streets, bike paths, unpaved roads and trails or some combination of those places? Your choices include road We give you a rundown of bike categories below to help you narrow your choices.
  2. How much do you want to spend on a bike? Bikes within a given category and price range generally have similar types of components. But expect to pay more for higher-performance components or frame materials such as carbon.
  3. How should the bike fit? Bikes come in a range of sizes, so start by finding the right frame size based on your height. Read more about Bike Fitting Basics. Cycle shops (like REI Co-op's) can help you fine-tune fit issues that arise after that.

Start by asking yourself where you plan to ride: on streets, bike paths, unpaved roads and trails or some combination of those places? Below is a simple chart with basic bike category options based on the surface(s) each is built for:

Riding Surfaces

Bike Types

Paved roads and bike paths

Road bikes, hybrid bikes and electric bikes 

Pavement (from pristine to potholed) and natural surfaces

Hybrid bikes and electric bikes

All-road riding (from asphalt to outback)

Gravel and touring bikes

Dirt roads and trails

Mountain bikes and electric bikes

Pretty much any bike can handle pavement, of course, and many bikes can be ridden on multiple surfaces. Narrow your choice based on where you expect to do the majority of your riding. You can also check out our more thorough rundown of bike categories below.

There's an Electric Bike for That, Too

Many bike types now include electric bike options, so take a few minutes to decide if an e-bike makes sense for you. Generally, an e-bike with a pedal-assist motor will greatly expand your riding possibilities. While these bikes come with a higher price tag, they allow you to zip up hills with less effort, as well as ride farther and faster.

Road Bikes

Road bikes are good for fitness riding, commuting, event rides, touring and racing. Most have a drop-bar handlebar (curling down and toward the rear of the bike), which puts the rider in an aerodynamic position. This bent-forward riding posture can take a little getting used to.

Road bikes come in the following categories, including several electric-bike models:

Endurance bikes: "Enduring comfort" might be a more apt name because these road bikes feature a relaxed geometry that helps keep you more comfortable on longer rides. Slightly wider tires give endurance bikes traction on a variety of surfaces, and the tires can be ridden at a lower pressure for a more forgiving ride.

Gravel bikes: Because cyclists have always pushed the envelope on where they can ride, multi-surface bikes have been a thing for years. Hybrid bikes (discussed below) are one option. Gravel bikes are an ideal choice, though, if you're itching to go a little faster and farther. Descended from cyclocross (now a class of elite all-terrain racing bikes), gravel bikes feature a drop handlebar for aerodynamic efficiency, along with wider tires for a forgiving ride and traction on terrain ranging from asphalt to gravel to dirt.

Touring bikes: Touring bikes differ from traditional road bikes in that they are built for riding loaded up with gear over long distances. They have sturdy frames to support heavy loads and have attachment points that let you add racks, fenders, water bottles, pumps, lights and more. A long wheelbase (the distance between the wheel hubs) helps make them easier to control when you have a heavy load.

Performance bikes: These light and aerodynamic bikes are built for going fast on the flats and charging up hills during group rides with friends, or for riding in organized races.

Mountain Bikes

Designed with shock-absorbing features and sturdy builds, mountain bikes can handle dirt trails and the rocks, roots, bumps and ruts that make them so fun. Mountain bikes have lower gears than road bikes so you can ride up steeper terrain.

Two frequently used terms are "full suspension," meaning a bike has both front and rear suspension, and "hardtail," meaning a bike has only a suspension fork. Full-suspension models tend to be more expensive, but they offer better traction and a more comfortable ride. They can also handle more varied terrain.

Mountain bikes come in the following styles, including several electric-bike models:

Cross-country bikes: Lightweight and responsive, this style of mountain bike originated in the racing world, so it delivers both riding speed and climbing prowess. It's a good choice if you want to ride off road on your fitness rides or if you want a nimbler bike for less technical local trails.

Trail bikes: This is the style most new mountain bikers will get. If social trail riding with friends on beginner-friendly trails and dirt roads is your goal, then this is your bike. Bikes in this category place equal emphasis on fun and efficiency.

All-mountain bikes: These bikes are a good option as you progress to riding on more technical terrain. All-mountain bikes are well-rounded performers: joyful on steep and flowing descents, while also being capable climbers. Their geometry balances the need for both uphill power and downhill stability, so all-mountain bikes can handle a variety of technical features along the trail.

Hybrid/Fitness Bikes

If you want something that performs well on the street but can also handle some unpaved terrain, this is your bike. You might also see hybrid bikes referred to as "fitness bikes" because their comfort and versatility appeal to riders motivated primarily by the exercise benefits of riding. Hybrid bikes generally have a more upright riding position than their road bike counterparts. Most have large-diameter road wheels for speed, paired with wider tires for off-road traction.

A tipoff to whether a bike is more for street riding is the absence of suspension. Hybrid bikes with front suspension are a good choice if you plan to spend more time off road—the tradeoff is a bit more weight and a little less speed in exchange for a cushier ride.

Factor in Performance and Cost

You don't have to analyze each technical component on a bike, but certain features and premium components can add to the price. When looking for a bike within your budget, keep in mind the following factors that can cost more:

  • Full suspension, hardtail or no suspension: Full-suspension bikes (front and rear shocks) generally cost more, but also offer a smoother ride and the ability to take on the most rugged trails. Hardtails (front suspension only) still absorb bumps, but do so for a little less. Further reading: Bike Suspension Basics
  • Carbon vs. aluminum: Lightweight carbon frames offer premium performance and ride quality—they also mean a leap in price. In contrast, aluminum-frame bikes can be found at every price point. Further reading: Understanding Bike Frame Materials
  • Going electric: Electric bikes expand the riding horizons for all riders. Further reading: Intro to Electric Bikes
  • Component quality: A bike's components—essentially all the major systems other than the frame and wheels—are usually part of a tiered group. As you move up to a higher price in a bike category, the corresponding component group will be more responsively tuned and add to the overall cost of your bike.

Bikes vary in the number of gears, the range of the gears (lower gears make it easier to pedal) and the available gear ratios. Generally, most models in a given bike category will have similar gearing. That means it's not something you have to think about unless you really want to.

Wheel Size

Wheel size is another bike feature that's largely predetermined by the bike category you choose, with one big exception: Most mountain bikes come with either 29" wheels or 27.5" wheels. From a cost standpoint, the difference isn't significant. So your choice is largely a matter of performance nuances.

Brake Type

In years past, rim brakes were the norm and disc brakes were the exception. Disc brakes have always offered superior braking power in all conditions, though, and they now dominate the market because the cost of disc brake technology has come down over the years.

Rim brakes, which work by squeezing the brake pads against the sides of the wheel rims, are still an economical option. They make it easy to check brake pad wear and to replace worn pads.

Disc Brakes, which feature brake pads that grip onto a brake rotor mounted to the wheel hub, come in two versions:

  • Hydraulic disc brakes offer more progressive and stronger braking with less finger effort, and they self-adjust for brake pad wear.
  • Mechanical disc brakes need manual adjusting as the pads wear.

Bike Size and Fit

Getting the right frame size is the first step. Fortunately, most bike manufacturers have size charts that list your frame size based on your height. The most important aspects of bike fit, standover height (the distance between your body and the top tube when you straddle the bike) and reach (the distance from seat to handlebar) can then be fine-tuned with some minor adjustments.

To learn more about how to fit a bike, as well as how to do adjustments at home, read Bike Fitting Basics and Mountain Bike Fitting Basics. Beyond getting the correct frame size, you'll also need to fuss with nuances like seat height.

REI Co-op stores and other cycling specialty shops will also adjust your bike's fit, either during a test ride or after you buy a bike. Tell them about any discomfort and they'll happily address your fit issues. Note, though, that you need to give your body several weeks to get accustomed to your new ride. It's a little bit like breaking in a new pair of heavy-duty hiking boots.
