What is the accurate bike size for you? Well, only a few people know the answer to this; let alone consider the question when purchasing their bikes. Most riders will just try on a bike. If it feels generally okay, they will buy it. This doesn’t have to be you.
Why Buy the Perfect Fit?
Choosing the right bicycle from a bike shop, such as The Yellow Jersey Bike Shop, will give you something faster, more comfortable and easier to ride. While the chances of getting a perfect fit aren’t always so high, you can always adjust a couple of adjustable bars to bring every dimension to perfect harmony with your body size and riding style.
Know Your Bike Size
To get your bike size, you will have to stand with your legs 15-20 cm apart and measure the distance from your crotch to the ground. This will be the ‘leg inseam’. You will also need to know your exact height. The bike size will vary depending on what bike you are using.
- City bikes: leg inseam (cm) x 0.685 = frame size
- Mountain bikes: leg inseam (cm) x 0.66 = frame size
- Road bike: leg inseam (cm) x 0.07 = frame size
The result will be in centimetres. You can convert it to inches since most bike frame sizes are quoted in inches.
Alternatively, you can use specific bike sizing charts that will compare your leg inseam and riding height to get the suggested frame size. Again, the chart values will vary from city bikes to mountain bikes and road bikes. Be sure to use the right one.
The last thing to do after matching the frame size is adjusting the saddle such that your foot will always be ever so slightly bent when the pedal is at it’s lowest position. This perfect saddle position is needed for maximum riding power. After this, take your bike out for a ride and tweak the position, or swap the bike until you get something that feels great.
