 "We had 'The Tandem Experience', a really excellent introduction to riding a bicycle made for two. Very thorough training on technique for riding a tandem (hint: it's quite different to a normal bike), then a whole day hire of a touring tandem, with a very pleasant 25 mile circular route map supplied. Bike was very good quality, and training unhurried and well delivered. Highly recommended, if you're thinking of trying out a tandem!" James McRae, Local Guide - Google Review

What frame size do we need?

A common question and one that we do take seriously as it makes the difference when riding a Tandem safely and for long term enjoyment.

How do we work this out? 

Here are some pointers we talk about regularly with our customers.

  • Your ‘Saddle Heights’ are critical and found commonly too low for efficient cycling.
  • Once your ‘Saddle Height’ is correct then your feet will only just touch the ground, by tip toe.
  • To find the correct ‘Saddle Height’ we require a ‘Standover’ measurement.
  • To do this simply stand with your back to a wall with your cycling shoes fitted, then place a book (approx. 30mm wide) between your legs and position so that it touches you firmly.
  • Then measure from the top of the book to the floor.
  • This measurement is your ‘Standover.’
  • Remove 100mm from this ‘Standover’ measurement and this will leave you with your ideal saddle height to start with.
  • The ‘Saddle Height’ is measured from the top/middle of the saddle to the centre of the chainset.

Now when looking at our Frame Measurements matrix below and look for the Standover in column ‘O’.  The measurement shown are the maximum of your Standover for front and rear riders.  Therefore you can look at frames that are lower than this.

Of course our Custom Sizing Option is  available if you are unable to fit the many sizes available.  We charge to produce a TandemCAD for you that is refundable once the Tandem is placed on order. Click below if you wish to go through this process.
