Sizing Guide

WHAT SIZE BIKE IS RIGHT FOR ME?

As a rider you want to feel comfortable on your bicycle. You want to make sure that your riding position is comfortable with some consideration for efficiency. So how do you choose the correct size?

The easiest way is to estimate the correct size based on your height. When you select the frame size option on the relevant product page, the recommended rider height will appear. There is also a reference table below.

Fortunately, Chappelli bicycles only come in a two sizes fit most solution, which makes it a lot easier to work out which bike is likely to be best for you.

If you are between sizes you may want to go up a size as a lot people prefer to have a little more room and be a little more stretched out on a bicycle, so generally a slightly bigger frame might be better suited. 

However if you are new to cycling or don’t feel very confident on a bike, perhaps a smaller frame would work better for you in terms of control and confidence.

If you are concerned about the correct size, the best method is to work out your stand over height (see below) and match that to the stand over height of the bicycle. Seat and stem heights can be adjusted to adapt to most riders.

HOW ARE BICYCLE SIZES WORKED OUT?

Bicycle sizes on road bikes and commuter bicycles are measured in centimetres and usually refer to the length of distance between the seat tube (where the saddle goes in) to the head tube (where the handlebars and front fork are). It usually corresponds to the length of the top tube if it runs straight from the seat tube to the head tube. The longer the top tube is the more stretched out you will be. Chappelli Cycles mostly use square frame geometry which means the length of the top tube is also the length of the seat tube.

CHAPPELLI SIZING GUIDE

Most of our bicycles (diamond frames) are currently made in two frame sizes: Medium (54cm) and Large (58cm) these typically fit the majority of people.

Chappelli womens bicycles (step through frame) come in one size, Regular 50cm frames.

However, if you are uncertain that these frame sizes are not right for you, please contact us by email and we can provide advice.

HOW DO I WORK OUT MY STAND OVER HEIGHT?

The stand over height is the height of the bicycle from top tube to the ground and should be similar to your inseam leg length so that if you stand over the top tube with the bicycle between your legs you can stand comfortably with your feet flat on both sides.

To measure your stand over height:

  1. Stand with your feet shoulder width apart. (with shoes on)
  2. Take a book or something similar and hold it between your legs as if it were the top tube of your bike. It should be as high as it will comfortably go.
  3. Now, measure from the top of the book to the ground making sure the book is level and the measuring tape is straight.

Ideally, when pedaling, you should have approximately a 30 degree angle in your knee. Much straighter and you risk over-extending, much more bent and you won’t be getting maximum power from each pedal stroke.
