Please note all sizing information is a guide only. Our size guides show as a pop up (above the size drop down menu) on each bike page.
Choosing the right sized bike depends on a few things: the type of bike, your height, your arm and leg length (in proportion to your height), your confidence and your riding style.
Having the right size bike means that you're comfortable and will be in control.
For a bike with a crossbar you should be able to stand over the top tube with around two inches of clearance.
Typically the ball of your foot (or feet) when you are sat on the saddle should just reach the floor, you shouldn't be on tip toes or lean over far to one side. Many riders prefer to have their feet flatter on the ground and that's totally fine simply adjust your saddle to a lower height.
If you choose a model with a suspension seatpost please be aware that the saddle won't go as close to the frame as a standard seatpost.
It's always best if possible to try for size in one our stores, if you are not able to visit us and have any questions about bike sizing please contact one of our team.
Most bike frame sizes are measured from the centre of the bottom bracket to the top of the seat clamp but can vary between brands. Please don't assume a size in one brand is the same as another and even model year sizing can vary. Cube leisure E-bikes (Kathmandu, Touring, Ella and Supreme) for example to most riders feel larger when compared to other brands. Cube mountain bikes are designed to be more maneuverable and therefore the frame size can feel smaller.
Most brand websites such as https://www.cube.eu/uk-en/ or https://www.haibike.com/gb/en will have a size calculator which you can refer to.
Wheel size also effects how the size of a bike feels overall. Some models in small or X-small will come with a smaller diameter wheel.
There are 3 main types of wheel sizes for non folding e-bikes, including 26", 27.5" and 29". The 29" wheel is also know as a 700c. Some electric mountain bikes have a 'mullet' set up where the front and rear wheel are different sizes!

It is very common for a size chart to recommend two frame sizes for your height.
No two humans are the same, we all have individual anatomy.If you are between sizes based on your height the fit is then determined by the reach which is the distance to the handlebars when sat on the bike. If you have a longer torso and arms the larger of the two frames maybe a better fit and vice versa for a shorter torso or arms.
Don't be tempted to go larger than you need, if the reach is too long your back will be too flat and your arms too straight, it won't be comfortable and you may even end up with back or neck pain.
If you find your new bike is too large please get in touch with our team, if it has less than 5 miles on the 'clock' then we normally can exchange for a smaller size. Customers very rarely report that their new bike is too small but again if this is the case an exchange can be arranged, read more HERE.
