And don’t worry about the old wisdom of trying a bike before getting it, that is quite definitely overrated. And very highly. Salesmen say this just as a means to get you invest in a bike.It really doesn’t have to do that much with finding the right size for yourself.

You should try your bike first! FALSE

Another reason is that salesmen know that there are decent bikes on the online market and the option of getting to sit on one gives them an apparent edge over that market, but in actuality it isn’t by any means necessary to choose a bike with the right size.

There are many good methods to choose a good bike. I’m gonna highlight THREE METHODS if you don´t know how to measure a bike.

Feeling more confident? Good. There are actually three different ways to pick a size: you can calculate it or use the bike size charts below. Let´s start with the easiest. The bike size is measured from where the seat post starts down to the crank. You can also use the bike height chart.

It’s easy!

  • 5’3″ – 5’7″  = 15 – 17 inches
  • 5’7″ – 5’11” = 17 – 19 inches
  • 6’0″ – 6’2″ = 19 – 21 inches
  • 6’2″ – 6’4″  = 21 – 23 inches

  1. Take off your shoes and stand with your legs 15-20 cm (6” – 8”) apart. Measure the height from the ground up to where your legs come together.
  2. Be sure about the bicycle type you want to choose: Mountain bike, city bike or road bike. You can read about the different bike types here.
  3. Now you can take your calculator and quickly find the right size:

Leg Inseam method
Right mountain bike sizing–  Leg inseam (cm) x 0,66 = Your frame size

For example: If your leg inseam is 76cm, then your right mountain bike size is 50 cm (20”)

Extra: Right Saddle Height

Right Saddle Height

Right saddle height has a very important role. If it´s too low, you won’t have enough power in your feet.In mountain bike racing, I have experienced that when the saddle falls one inch down from its normal position, I lose about 25-50% of my force.

Stopping to fix it can cost me my position and about 15 seconds too, but then with the correct saddle height it’s not that hard to catch up with the group and even can get all the way to the next group ahead. So the right saddle height plays huge role!

 

The easiest way to find that height for you is to

  1. Lean against the wall with your elbow sitting on bike (or let someone help you as shown in the picture)
  2. Push your leg down to the lowest point keeping it parallel to the ground.
  3. Move your saddle up or down until you have small bend behind your knee. It should be something around 30° but don’t worry too much about finding that exact angle.

Go out and ride. Does it feel good? If not, then adjust. Also, you can adjust the seat forwards and backwards. TIP: When you have found the right position for yourself

Suggested bike by Bicycle GuiderBicycle Guider TIP:

When you have found the right height for yourself, you can use a marker or a sharp object to mark the right position for your saddle as some of them can sink down a bit with time. Some bikes also come with height lines written on the post, that you can check and remember once you’ve found the right one for yourself.

If I Got My Bike Size Wrong?

Then tell the merchant, who can easily exchange your bike for the right one. If you don’t want to do that, then you can do the following things:

  • move your saddle forwards or backwards
  • buy a longer or a shorter stem. It will change your body position
  • buy a longer seat post

Give it time to get the feeling right. I remember when I got my first 29er mountain bike. It felt like a ship and seemed difficult to ride it in narrow trails or the forest. But I’ve become so familiar with it and can ride with full ease and skill, that when I sit on a 26″ mountain bike it seems so completely ridiculous how tiny it is.
