Sizing a bike is an unenviable task. In addition to the grueling steps, you’ve to follow while sizing a bike, the danger which a wrongly sized bike creates for a rider also keep you in check. Had you decided to go for an over-sized bike, it would deprive you of the most important safety feature: your feet. Since they will be no longer able to touch the ground, your feet might not come to your help in time of need.
Furthermore, had you gone the exact opposite – i.e. for an undersized bike, it would force your knees to bend when pedaling. Consequently, joint pains will become the norm.
Hence, as evident from the two unwanted scenarios mentioned above, it is crucial that you correctly size your bike. Thanks to these reasons, and many others, we have decided to teach cycling enthusiasts on how to size a bike.
Step # 1: Choose Frame Type:
If you’ve gone for a road bike, there are two frame types there: C-C and C-T. However, if you’ve opted for a mountain bikes, frame types come in aluminum, steel, and carbon.
Regardless of the type of bike you’ve chosen, make sure that your feet touch the ground while being seated on the seat post. In case they don’t go for a smaller bike. Also, if the heels of your feet are touching the ground, go for a larger bike.
Thus, while you could select the frame type of your choice, it is imperative you follow the above guidelines afterward.
Step # 2: Measuring the Inseam
In order to measure your inseam, stand in front of a wall with your back touching it. Now, place a book between both your legs in your crotch. Finally, ask someone to measure the distance from the top of the book to the ground. This is your inseam.
Step #3: Measure your height
Imagining that you’re doing all these steps in one go, take out the book from between your legs. Now, without wearing any shoes, stand upright with your back against the wall. Again, ask someone to measure the distance from the top of your head to the ground.
Note: If you want to save yourself from egregious calculations in front of a shopkeeper, make sure that you’ve measured your height in inches.
Step # 4: Calculate the frame size
If you’ve gone for a mountain bike, calculating the frame size isn’t imperative. However, in the case of a best cruiser bikes, it could make a world of difference.
Provided that you’ve gone for a C-C type of frame on a cheap road bikes, multiply your inseam with 0.65 to get the frame size. For a C-T type frame, multiply it with 0.67. Although trivial, you SHOULD take this difference into account to get a comfortable road bike.
Step # 5: Measurement of Total Reach
Unlike the above-mentioned steps – all of whom are crucial to you landing a perfectly sized bike, this step is more dedicated to your comfort level. Hence, while I don’t recommend it, you could skip this step if you feel like it.
To measure the total reach of your hands, spread them in the horizontal direction. As you might guess, ask someone (AGAIN!) to measure the distance from the tip of one hand to the same of the other. For future calculations, note down this measurement as A.
Secondly, go back to STEP 2 and repeat its first part. This time, however, your accomplice would measure the distance from the bottom of the book to your shoulder height. Note down this measurement as B.
Now, applying the following formula, you’d get your total reach.
Total Reach of Your hands = A + B / 2
Step # 6: Go for the bike of “your” choice
Using the above-mentioned measurements, go to a bike shop and get the bike of your dreams. While your choice is also crucial, don’t forget that these measurements are equally important. Good luck.
