Mountain biking is a great way to get outside and enjoy the fresh air while also getting a workout.

How are Mountain Bikes Measured?
The best mountain bikes are typically measured in two ways: by the frame size and by the wheel size. The frame size is the distance from the top of the frame to the bottom bracket, and it is usually measured in inches or centimeters. The wheel size is the diameter of the wheels, and it is usually measured in inches. There are some best 26-inch mountain bikes whereas some newer models have 27.5- or 29-inch wheels. The frame wheel size can be used to determine the overall size of the bike, which is important when choosing a bike that will fit you well.
Remember that the seat tube length will give you a good idea of the bike’s overall size, but it’s important to keep in mind that rocky mountain bike often has sloped top tubes, which means that the actual height of the bike may be less than the seat tube length.

Tips for Choosing the Right Mountain Bike Size
You can apply these tips on whichever model you like ranging from Best mountain bike under 600 dollars to Best mountain bike under 2000 dollars. Here are the tips for finding the right mountain bike size chart by height:
1. One method is to simply consult a size chart. These charts can be found online (above) or at your local bike shop, giving you a good starting point for finding any bike be it best hybrid bikes or the best full suspension mountain bike. You can find the right size for you anytime.
2. Another way to determine what size mountain bike you need is to take your own measurements. First, measure your inseam, which is the distance from your crotch to the ground. Then, compare this measurement to the standover height of the bikes you are considering.
The standover height is the distance from the frame’s top tube to the ground. You should have at least 2-3 inches of clearance between your inseam and the standover height of the bike; any less than this and you run the risk of being too cramped on the bike or having your legs hit the pedals when you’re riding.
3. Once you have determined what size mountain bike you need, it’s time to start test riding! This is the best way to find a bike that feels comfortable and suits your riding style. Most bike shops are happy to let you take a few different models out for a spin, so don’t be afraid to try out a few before making your final purchase for the right mountain bike size for height.
