Important Factors Of Best Bike Under 400 You Should Know

 Best Bikes Under 400

For newbies who want to join cycling, selecting the best bike isn’t only about design, cost but also about the purpose of cycling and the quality of every bike’s part. Here is our criteria with the hope to support you to pick the most suitable bike for yourself.

Usage

If you are just a fan of cycling during daily activities such as commuting or wanting to improve your health, a hybrid bike will be a brilliant idea for you. If you love to join adventure sports such as mountain climbing, you will need a mountain bike due to its durability and flexibility. However, a road bike will be a good choice if you want to experience bike racing. 

Size 

The bike size is one of the most important factors that determines the quality of your cycling. We recommend that you should carefully read the specifications of the bike to make sure that it fits your body. Or you can ask the manufacturers on their website, so they can give you the most practical advice on how to choose the suitable bike size. 

 Best Bikes Under 400

Frame material

The next component that contributes to creating a high-quality bike is frame. Nowadays, bike manufacturers often select popular materials such as aluminum, steel and carbon to make bike frames. Let’s consider these materials one by one!

Aluminum frame

Aluminum is a fairly favorite material of both bikers and manufacturers because they are not only light, quite sturdy, but also affordable. Another advantage of aluminum is that it is corrosion-resistant, which ensures the durability of the bike in wet conditions. However, the aluminum's stiffness can cause the bike to absorb road noise as well as other materials. Thus, this is not a good option for long-distance journeys.  

Steel frame

Steel is thicker and stronger than aluminum. It is not only durable and deformation-resistant but also can be easily repaired. The downside of this material is its heavy weight, so it's not integrated for premium bikes. Also, steel-framed bikes are susceptible to rust in wet weather and under the action of oxygen.

Carbon frame

Finally, many bike companies have used carbon - the most unique material in producing bike frames. Some enormous advantages of this material are ultralightness, excellent stability on rugged terrains and especially unlimited longevity. Because of the fact that making a carbon frame will take a lot of time and difficult steps, it is inevitable that carbon frame bikes are much more expensive than other bikes. It focuses on maximum performance and satisfies professional racing cyclists.

Groupset

Groupset plays a pivotal role for bikes; it is not only the engine that drives the whole bike, but also the key factor for the bike’s performance on each different terrain. They are included components such as chainset, bottom bracket, brakes, brakes levers, shifters, derailleurs, chain and cassette and these components work as a whole, helping the bike to operate smoothly. Currently, the most well-known technology that is applied to groupset is Shimano. It is a favorite brand of bike lovers because of its affordable price and excellent performance. 

Wheel & Tire

If you're looking for the best bike under 400, you should definitely not overlook the other two important factors, which are wheel and tire. The larger the tire width, the higher the bearing capacity, offering bikers a softer ride on rough terrain. Plus, wide tires have better grip and higher safety on rough roads. Yet, a wide tire will reduce the vehicle's speed. Wheels with small tires will increase speed of the bike by not creating too much friction with the road, but that is also their disadvantage because the grip is not high, leading to danger.

 Best Bikes Under 400

Front suspension

The front suspension is a common feature of many bikes today. Choosing a good suspension not only guarantees the safety of your vehicle, but also helps absorb shock better from the terrain giving a sense of comfort and confidence for the journey to conquer and get through difficult terrain with ease. Currently, some hybrid bikes are equipped with suspension under the saddle. This new type of suspension is an excellent absorber for the cyclist when going through rough terrain or macadam. 

Saddle

The saddle of a bike is an important accessory because it greatly affects the user's driving position. Choosing the unsuitable saddle will have a bad impact on the pelvis, spine, and buttock will be tired. Depending on the cycling purposes, you can choose different types of saddle with different widths. If you are choosing a saddle for high-speed racing, the saddle should be narrow made of hard leather to reduce the distance and area between the thighs, creating faster speed without spending much energy. If you merely want to enjoy a relaxing ride, a bit wide cushioned saddle is a perfect option. If you experience mountain climbing, you have to install a medium-sized saddle for easier off-road trips.

If you still have questions about the above criteria, please watch the following video to better visualize the important factors that make the best bike!
