Bikester frame calculator
You can easily calculate the frame height in just 2 steps:
1. Determine the correct step length (step height)
You will need a tape measure and a spirit level. A book will do if you don't have a spirit level.
Remove your shoes and any loose fitting clothing. If you have a spirit level, place it horizontally between your legs (use the example on the right as a guide). It works the same way with a book, but you should place yourself against a door or wall so that the top of your measuring instrument is parallel to the ground. Measure from the ground to the spirit level or the book with the tape measure. The length on the tape measure is your 'step length'.
