Buying Guide

If you’re looking for the best mountain bikes under 300, there are several factors which come into play.

  • Type: mountain bikes may be classified by their suspension.
    • Hardtail mountain bikes have a front suspension fork
    • Full suspension bikes have rear and front shock absorbers
    • Rigid bikes don’t have any suspension

Beginners will probably feel most comfortable with a full suspension bike, but if you’ve got experience or looking for more challenge, a hardtail bike may be more appropriate.

  • Durability: the best mountain bikes under 300 are built to last, but even these will need maintenance if used frequently on rugged terrain. While you will spend less than $300, you have to set aside a small budget for maintenance and upgrades.
  • Frame Material: alloy, steel, and aluminum are the most common types you’ll see. Most mountain bikes in the sub $300 price ranges are aluminum or steel, but between the two, aluminum is lighter.

However, steel is cheaper and doesn’t need as much maintenance provided you make sure it doesn’t rust. Carbon and titanium frames are found only on expensive mountain bikes.


Most mountain bikes have 26-inch wheels, and you may want to use these as well. Once you’re comfortable with these, you can try the 27.5 or the 29-inch wheels.


the best bicycle under 300 needs to have an adjustable and comfortable seat. Whether you’re going off the beaten path or cruising around town, a padded seat is a must.


Look for quality gear hubs as they don’t need a lot of maintenance. The good ones last for more than a decade without any serious upkeep. Derailleur gear systems are the most versatile and offer up to 30 gears or more.


Distance refers to the distance between the bars and the saddle. The best way to determine this is to test ride the bike.


Mountain bikes have brake pads which are connected to the hub. There are two types:

  • Hydraulic disc brakes offer more powerful braking, require less effort from you and have more adjusting capabilities.
  • Mechanical or cable activated brakes require manual adjustments.
  • Brake pads are more consistent and reliable than rim brakes, and they provide generally better performance. The drawback is they can be difficult to assess and replace. They also cost more to repair.

Test Drive

No matter what type of mountain bike you buy, whether it is online or in a store, always try it out first.
