Welcome to the Folks on Forks Family!!

When sitting on a bike should your feet touch the ground?

Correct seat height; You can only touch the ground with your toes. Many bicycle commuters will stop and use the curb since they can’t reach the ground without a “boost.”

"Usually, you cannot touch the ground with both feet when sitting on the saddle - but you should be able to reach the floor with the ball of one foot"

— The Long Distance Cyclist’s Handbook

Proper saddle height is very important.

Too low of a saddle is hard on your knees and is very inefficient. Too high of a saddle and you can’t get any leverage on the pedal cranks and is very uncomfortable.

Either way, a saddle that is too far up or down is bad, uncomfortable, inefficient, and will eventually lead to injuries or pain.

Should my feet touch the ground on a bicycle when I’m sitting in the seat/saddle?

For most styles of bicycles, including road, gravel, and mountain bikes, you’re at the CORRECT saddle height when you can only touch the ground with the TIPS of your toes while your ankles are flexed with your toes pointed downward (see pic below).

If you can sit on your bike seat with your feet flat on the ground, then your saddle is much too low.

Notice this mountain biker can only touch with the tips of his toes while reaching down with his foot. This cyclist is riding with a correct saddle height

Above are the instructions from the Specialized Bicycle Owner’s Manual.

Basically, your crotch should be 2 to 6 inches higher than the frame when straddling the bike. Once you go from straddling the frame to straddling the saddle, you should only be able to reach the ground while being on your tippy-toes.

BICYCLE SEAT TOO LOW

It’s very common for beginner and intermediate cyclists to ride with their seat too low since they feel more comfortable being able to reach the ground.

However, riding with a saddle that is too low reduces pedal efficiency and overtime causes knee problems.

“Biker’s Knee” or Patellofemoral Pain Syndrome (PFPS) is the most common knee injury to cyclists and is caused in part, by riding with the saddle too low.

Saddle Too Low & Problems

Pain in the front of the knee or on the kneecap (patella)
- More common in recreational riders than amateur or professional cyclists
- Caused from riding with too low of a saddle or sitting too far forward in the saddle
- Saddle Too Low = Knee is more flexed = causes compression of the patella against the underlying surfaces = excessive amount of shear forces pulling the patella = anterior knee pain
Limited knee extension = reduced pedal efficiency and power
- Reduced Efficiency - You will have “smaller” pedal strokes, which means you will need to pedal more to maintain the same speed as your friends
- Less Power - It’s hard to generate any serious power when you’re essentially turning your long legs (levers) into short legs (levers)

Seat too high. Zero bend in my knee and can barely reach pedal even when scooting up on the saddle

BICYCLE SADDLE TOO HIGH

Riding with a saddle that is too high is just as bad as riding with one that’s too low, but for different reasons.

Saddle Too High & Problems

Saddle sores: Hips rock back and forth against the saddle causing sores (and a waste of energy)
Causes pain behind the knee from overextending
Uncomfortable from over-reaching and excessive rubbing on the seat
Not a very powerful position as your trying to spin the pedals from a very weak position

You know the seat is too high when your riding and your hips are rocking back and forth.

In the above picture, this cyclist has a saddle that is too high as he has excessive hip motion or rocking. However, you don’t want to eliminate all hip motion, since the ideal amount of pelvis movement transfers more power to your legs.

OPTIMAL SADDLE HEIGHT

There are numerous formulas and techniques for finding your proper saddle height, such as the Hamley, Lemond, Holmes, Pruitt, and heel-toe methods.

Finding Your Seat Height Quickly & Easily: Heel-Toe Method

The heel-toe method is the quickest and easiest way to find your approximate ideal saddle height and also requires no specialized equipment.

The heel-toe method:

Sit on the bicycle with both feet on the pedals
Prop yourself up (hang onto a wall, use a trainer, or ask a friend to help)
Pedal backward until:
- The bottom pedal is in the 6-o’clock position
- The top pedal is in the 12-'o’clock spot
Place your heel on the low pedal and your leg should be fully extended
Go for a ride. When you spin the pedals your leg should have a slight bend (25 - 40 degree knee angle) while in the bottom position
- This is just an approximate starting point and you can make adjustments up or down, from this position

Final Thought

Of all the bike fit adjustments, saddle height is considered the most important.

Optimal seat height allows you to maximize every spin of the pedals while keeping your knees healthy. You will make over 7,200 pedal revolutions in just a leisurely 2-hour bike ride. If your seat isn’t set properly, your body will let you know.
