How do I measure my height?

With your shoes off, stand upright against a wall, with your shoulders back and legs together. Use a pencil to make a small mark on the wall above your head – make sure you hold the pencil parallel to the floor. Then measure from the floor to your mark, in centimetres or feet and inches.

How do I measure my inside leg length?

With your shoes off, stand upright with your back against a wall. Place a book/ruler between your legs, level with your crotch. Then measure from the floor to the top of the book/ruler, in centimetres or feet and inches (it’s easier if a friend helps).


Q & A

How are hybrid bikes sized?

Hybrid bikes combine features of both road and mountain bikes, and they can be sized in inches (like mountain bikes), centimetres (like road bikes) or using a S/M/L system. A hybrid bike frame size is calculated by measuring the length of the seat tube, from the centre of the front chainring to the top of the tube (where the seat post inserts). NB. Sizes can vary slightly between manufacturers.

I’m between sizes – which hybrid bike size should I choose?

If your measurements suggest that two hybrid bike sizes are suitable, then in the end it’s a personal choice, but the rule of thumb is to choose the smaller size. That’s because it is possible to make a smaller hybrid bike frame bigger (for example, by raising the saddle or fitting a longer stem), whereas if the frame itself is too big for you, it’s likely to be less comfortable and less efficient.

Are frame sizes different for women-specific hybrid bikes?

Yes – for example, a Medium women’s bike will be smaller than a Medium men’s bike. However, the sizing itself is calculated in the same way, so a 17” men’s and women’s bike have the same frame size.
