Bicycle Saddle Height

Features Bicycle Saddle Height

This app will allow you to calculate your ideal bicycle saddle height (BSH) according to your body anatomy, to protect your legs from overstretch but at the same time to protect your knees from bending too much.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 HeightP3 - Seated HeightP4 - Upper Legs Width (or HJCR Height)P5 - Knee HeightP6 - Ankle Knuckle HeightP7 - Ankle Knuckle to Ball Foot (or to Axis Pedal Center)P8 - Pedal Height (Flat or other type )P9 - Saddle Minimum HeightP10 - 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 - InseamThis 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 bottomS2 - Best Beginner 145 degrees knee angle with pedal at bottomS3 - Cycling Shoes - Max Ankle Angle Max available leg extension with cycling shoesS4 - Flexible Shoes - On toes Max available leg extension with flexible shoesS5 - Optimum crank - Expert New crank length 155 knee angle at bottom + 70 at topS6 - Optimum crank - Beginner New crank length 145 knee angle at bottom + 70 at topThe METHODS are:M1 - Greg LeMond Saddle Height 88.3% your inseamM2 - Hamley-Thomas Saddle Height 109% your inseam minus crank lengthM3 - Heel Heel with the pedal at the bottom and knee lockedM4 - Holmes-Pruitt Knee angle 155 degrees with the pedal at 6o clockThe 6 setups and 4 methods will give you the following 7 Outputs:O1 - Saddle HeightO2 - Maximum Frame SizeO3 - 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 BottomO7 - HJCR (Hip Joint Center of Rotation) to BB (bottom bracket)You can use this info to set your ideal saddle height, but remember that everyones 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.
Youll 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!
