Bike Size FAQ

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.

How is the frame size measured?

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.

How do I choose the correct frame size?

Choosing the right sized bike depends on a few things: the type of bike, your height and your riding style. A correctly fitted bike will be more comfortable, more efficient and more fun to ride allowing you to go further for longer. The type of bike that you buy will have a significant impact on the frame size that you need.

We recommend a test ride where possible. This allows you to try different frame sizes and allows our team to recommend a size for you too based on their experience.

What if I am between two 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.

How high should my saddle be?

Correct saddle height is important not only for comfort but for pedalling efficiency too.Here is a simple method to set the correct saddle height:

1. Whilst stood next to the bike, set the saddle to the height of your hip bone. Ensure the saddle is not extended past the minimum insertion mark on the seat post. If this is the case you may need to consider a larger frame.
2. Using a wall, table, chair or friend holding the bike for you, sit on it with both feet on the pedals. Rotate the pedals back so that the crank arms are at 12 and 6 o clock. On the lowest pedal move your foot forward so just your heel is on the pedal. In this position you should aim for your leg to be straight but not locked out. Keep adjusting the saddle height until your leg is straight.
3. Once you have set your saddle height place your foot on the pedal at 6 o clock in your normal riding position. At this point your leg should have a bend at the knee.
4. This method provides a good starting point for, what should be, a comfortable and efficient riding position for most people. This is of course is just a guide so feel free to make any adjustments you need for your own comfort.
