Things to Consider before buying

Before getting too excited, you should know the basics before buying to get the best out of your budget.

First, determine your bike style. Get a cross-country bike (XC bike) if you want routine biking or racing. You can go for a hardtail (with front suspension) or a full-suspension bike (with both front and rear suspension).

Get an enduro bike with more travel capacity than normal trail bikes if you want to ride downhill and on complex trails. For heavy-duty performance, a full-suspension system comes with it.

If you want to ride on steep and technical tracks quickly, opt for a downhill bike with a coil-sprung suspension for perfect support.

Second, take a look at the frame material. At this price, you may encounter steel and aluminum frames. Steel can tolerate a good beating and can last a lifetime as long as it is well-maintained against rust. But aluminum frame ensures lightweight than steel.

It is strong and stiff and can stand hard knocks. However, it has a weaker fatigue life. Considering these, it depends on how long you would want to keep your bike. Steel can last in the long run, but it would take tremendous maintenance in a wet climate.

Your weight is also a big factor, so opt for a strong enough frame with sufficient elongation. Among the two, steel is less expensive, but emerging aluminum frames are at the same price level.

Wrapping Up

Do not be intimated by the high-priced models even if you’re on a budget. As you can see in the list, you have many options to choose from, and you can get the best mountain bike for you for a low budget of 300. Even if they are low-cost, they do not disappoint in terms of strength, durability, and top-notch performance.
