How to Choose Your Bike Size [ The Simplest Way ]
Bikes are a lot of fun, but figuring out the right size for you can be tricky. Do you need a small, medium, or large bike?
What about a road bike or mountain bike? What’s the difference, and which one is right for you? Check out our easy-to-follow bike size charts to find the perfect bike for your needs.
Whether you’re a beginner just starting out or an experienced cyclist looking for a new challenge, we’ve got you covered!
To find the correct sized bike you will need to measure your height. To get an accurate measure, stand against a wall and mark the wall with a pencil so it’s level with the top of your head. Then measure from the ground up to the mark. That’s it, simple as that.
Now let’s find your bike size for each type:
