So we have to depend on our bodies. 

How to find out the size depending on the body? It’s very simple, you just need to know your height or inseam and you can know your mountain bike in minutes. I have the calculation process and size chart for you. 

By following my instruction below or matching with height, you can know which size bike is right for which rider. So let’s scroll down without dragging anymore.   

Does Mountain Bike Size Matter

Yes, mountain bike size matters. Just like all of us don’t fit in the same shoes, we don’t even can’t ride the same size bike. 

To enjoy the most rewarding experience while riding, first and foremost, you need to ensure you are using the right size mountain bike. A right-size mountain bike will ensure more comfort and better control. 

When you have the wrong size mountain bike that can’t accommodate your body, it will be difficult to handle the bike on trails. For example, if you have a small size bike, you will face pedal efficiency problems, be unable to keep the bike stable, and managing the speed will also be tough. These will lead to a crash and serious injuries. 

But when you have the right size mountain bike, there will be no struggle to handle the bike even at higher speeds. The bike will be more responsive, and safe to ride over rough terrain with full stability.
