Frame size
Buying a bike online is easier than you think. Here’s some information on how our bikes are sized up and how to measure all of the important parts of your body like they never taught you in school. If you’re still unsure, then email us and we’ll do our best to help.
How are bike frames measured?
Bike sizes are taken from the seat tube length. This is the measurement from the centre axle bolt (bottom bracket) to the top of the seat tube.
Choosing the right size
Each product page shows a height range for the frame sizes available (check the ‘Size & Spec’ tab). For even more accuracy, find yourself a tape measure and follow these steps:
- Stand against a wall with your shoes off
- Keep your legs together and your shoulders back
- Place a pencil flat on top of your head and mark the wall
- Measure the distance from the mark on the wall to the floor
Stuck between sizes?
If you’re between sizes, then the next step is to hold your arms out like a golden eagle and measure your wingspan (sound effects are optional).
- Hold your arms out and measure from fingertip to fingertip across the top of your chest.
- To find out whether you have a short or long reach, calculate your ‘Ape Index’ (your arm span measurement minus your height).
- If you have a positive Ape Index, then go for the larger size. If you have a negative Ape Index, then go for the smaller size.
All of our sizes take into account the stand over height (clearance between the top tube and your private parts) and allow around 1 to 2 inches clearance.
