Sizing guide

To make sure we get the sizing right on your new tandem, there are a few pieces of information we need from you and your riding partner. Firstly, we need to know your ride heights which you can measure on a solo bike or a tandem.

To work out ride heights:

*Ensure the pedal is set at the furthest point away from the saddle.

*Measure from the saddle to the top of the pedal as shown in the image on the left.

If you are are planning on buying your tandem mail order we also need to know:

*The distance from the nose of your saddle to the centre of the handlebars

*Whether your handlebars are higher, lower or level with your saddle.

We are always on hand to help with sizing so if you need any advice, please do call us on +44(0) 1756 748822 or email
