This app will allow you to calculate your ideal bicycle saddle height (BSH) according to your body anatomy.

The calcs will take in account the knee angle when the pedal is at the bottom and at the top and also the crank length, the pedal and shoe heights to help protect your knees from injuries.

If your bicycle is a road, mountain, trekking, cross, single speed, city, recumbent or even a trike or a velomobile you can use this app to achieve your saddle height for different bikes and equipment.

To find out your BSH, 12 parameters are necessary:
P1 - Total Height with Shoes
P2 - Total Height
P3 - Seated Height
P4 - Upper Legs Width (or HJCR Height)
P5 - Knee Height
P6 - Ankle Knuckle Height
P7 - Ankle Knuckle to Ball Foot (or to Axis Pedal Center)
P8 - Pedal Height (Flat or other type )
P9 - Saddle Minimum Height
P10 - Saddle Position (back or fore)
P11 - Crank Length (50 to 300 mm)
P12 - Seat Post Angle (0 to 90 degrees)
For the Greg LeMond and Hamley-Thomas methods, 1 parameter is necessary:
P13 - Inseam

This app will give 6 Setups to set your saddle and 4 of the most common Methods available for comparison.

The SETUPS are:
S1 - Best Performance
155 degrees knee angle with pedal at bottom
S2 - Best Beginner
145 degrees knee angle with pedal at bottom
S3 - Cycling Shoes - Max Ankle Angle

S5 - Optimum crank - Expert
New crank length 155 knee angle at bottom + 70 at top
S6 - Optimum crank - Beginner

The METHODS are:

M2 - Hamley-Thomas

M3 - Heel

M4 - Holmes-Pruitt
Knee angle 155 degrees with the pedal at 6'o clock

The 6 setups and 4 methods will give you the following 7 Outputs:
O1 - Saddle Height
O2 - Maximum Frame Size
O3 - Actual crank length or Optimum Crank Length (only setup S5 and S6)
O4 - Knee Angle at Top
O5 - Knee Angle at Bottom
O6 - Ankle Angle at Bottom
O7 - HJCR (Hip Joint Center of Rotation) to BB (bottom bracket)

You can use this info to set your ideal saddle height, but remember that everyone's anatomy is different and using a standard crank length (170/175 mm) might not be the best solution for you!

In the "Settings" you will be able to change the knee and ankle angles according to your preferences. You'll be able to save your own parameters, your friends or family, and edit or calculate it later on.
The parameters can be in mm (SI) or feet and inches (imperial) and must be defined in the "Settings".

Protect your knees and enjoy cycling more!
