What size bike do I need?
Bike Size Guides are a great way to help you find the right bike, and whilst the best option is to visit in-store to try a range of bikes and sizes, we’ve created our bike size chart to help you when shopping online for your new bike.
As you may find when shopping for items such as clothing or shoes, all bike brands size a little differently with their own sizing matrix. It can be quite tricky to compare between them, so this guide will help you understand the general sizing that may be best suited for you.
The bike frame size guides are based on an average build, and therefore it will need to be considered if you have shorter arms or longer legs for example.
We recommend that these sizing guides are always used in combination with brand-specific sizing that can be found on each bike’s information page.
For electric bikes, the same sizing guidelines as the relevant non-electric bike category apply.
Please note: These Sizing recommendations are to act as a guide. Should you have any questions about suitable sizing for your bike please contact our advice team.

What if I am between bike sizes?
Generally, whether you size up or down is related to personal preference. With sometimes marginal increments in size, you will likely be able to ride both the smaller and larger size, however, the best fit ultimately will be determined by the size that provides the riding position you are looking to achieve or the most comfortable for you. Stem length, Handlebar width, and even Crank length can be changed to achieve the ideal riding position which allows you a degree of flexibility when it comes to between sizes.
Is sizing different between men’s and women’s Bikes?
Yes. Whilst some bikes are unisex, bike geometry on women’s specific bikes is slightly different to men’s, to allow for a more comfortable ride and better fit, due to differences in average body proportions. However depending on the individual, their measurements, and adjustments that can be made to the bike – no one is limited! So be sure to browse both Men’s and Women’s options to find the right bike for you.
